Maria Valtorta and the Holy Shroud: the Problem of the Covering Hand (29 December 1943)

Context of the vision

In the night of 28 to 29 December 1943, Valtorta receives a joint vision of the adult Jesus and the Virgin Mary, near her bed. She recites her rosary while contemplating the sorrowful mysteries and wonders inwardly: she has never clearly seen the wounds of Christ's hands, which always seem closed or veiled by the sleeve. Later that day, Jesus dictates to her the precise anatomical explanation which Valtorta records in her Notebooks. The dictation is addressed to her spiritual director, Father Romualdo Migliorini, OSM, who at the time required that everything be put in writing^[3].

The excerpt is known under the internal title "The wounds in the palms". It takes the form of a monologue of Jesus to Valtorta. Its apparent interest: to explain why the visionary has never seen these wounds, although she regularly sees the pierced side, the thorn-crowned forehead and the feet. Jesus combines two reasons (habit, clothing) with a third, more unexpected datum: an anatomical detail fixing the relative position of the hands on the Shroud of Turin.

Full text of the dictation

The central passage, in the French reference translation of the Notebooks of 1943 published by the French Valtortan publisher, reads as follows.

"The wounds in the palms, which you have not seen because I rarely move my left hand — both from a habit contracted at work and because it is the most wounded —, were inflicted in the following way.

The executioners' idea was to suspend me by the wrists, immediately above the joint of the pulse, to make the suspension more solid. And indeed, after laying me out on the cross, they pierced my right hand at that point.

But, since the builder of the scaffold had marked the hole on the left farther from the point my wrist could reach, it was decided, after stretching my arm until the tendons tore, to drive the nail into the centre of the palm, between two metacarpal bones. It cannot be seen in the shroud because the right hand covers the left hand." — Jesus to Maria Valtorta, The Notebooks of 1943, dictation of 29 December 1943^[4]

The dictation continues immediately with a description of the differential effects of the nailing on each hand.

"The wound to the limbs, which I suffered in my lifetime, was greater because, once the cross had been raised, when the weight of the body shifted downward and forward, the nail made a large laceration toward the thumb, widening the hole more than in the right hand, where the wrist resisted the suspension better than the metacarpal. […] The left hand truly closed into a fist because of the spasm and the severing of the cut nerves. […] The wound in the right hand is almost completely hidden by the sleeve, and it is smaller and more regular." — Jesus to Maria Valtorta, ibid.^[5]

Valtorta's three anatomical claims

The dictation contains three factual claims to be isolated very precisely, for each will be confronted with the testimony of the Shroud:

1. Position of the nail in the right hand: "the right hand" is "pierced" at the wrist (carpus) — the first nail driven in, in line with the executioners' initial plan.
2. Position of the nail in the left hand: "the left hand" is pulled "until the tendons tore" — the rope stretched the arm — and the nail is driven "into the centre of the palm, between two metacarpal bones". Hence the palm.
3. Relative position of the hands on the Shroud: "the right hand covers the left hand" — so the right is on top, the left underneath, and it is the double asymmetrical wound (right wrist + left palm) that the overlapping makes invisible.

These are the three claims that must now be compared with the actual image of the Shroud.

A contact imprint, hence a laterally mirrored image

The Shroud of Turin is not an ordinary photograph taken from a distance. It is a contact imprint (or a very-short-range emanation imprint, according to the physical models of John Jackson, Eric Jumper and William Ercoline developed within the STURP framework in 1978-1981)^[6]. The linen cloth was laid over the body and covered it: the upper half was folded back over to wrap the front, the lower half remained in contact with the back. The image printed itself on the superficial fibrils of the linen fibres, chiefly through a phenomenon of localized oxidation and dehydration which contemporary science is still unable to reproduce identically^[7].

A fundamental geometrical consequence: the body's anatomical right (for example, Christ's right cheek) comes into contact with an area of the cloth which, when that cloth is laid out flat and photographed, appears on the observer's left. And vice versa. Everything that follows in this case rests on this simple lateral inversion.

An optical consequence: the resulting image is laterally reversed with respect to a body seen in normal view, exactly as a fingerprint or a wax seal is with respect to its source. This is what Dan Porter sums up in a formula that has become classic on the English-language reference forum:

"Your right-hand side will be projected onto the left side of the blanket image, and vice versa…just as looking in a mirror." — Dan Porter, Getting the Left and the Right Right, shroudstory.com, 26 December 2012^[8]

The term "mirror" is metonymic here: it is not a luminous reflection in the strict optical sense, but a lateral inversion produced by the very mode of formation of the image. Werner Bulst and Heinrich Pfeiffer, in their German reference monograph Das Turiner Grabtuch und das Christusbild (Knecht, 1991), phrase it in more cautious terms but reach the same conclusion: the positive image must be read as a reversed projection of the real body^[9].

The decisive test: the lance wound

The mirror inversion is not a mere theoretical intuition. It is verified by an independent consistency test which the whole Christian tradition supplies: the lance wound. According to the fourth Gospel, "one of the soldiers pierced his side with a lance, and immediately there came out blood and water" (John 19:34). The unanimous iconographic tradition, the Christian art of the first two millennia, Greek and Latin patristics, and nearly all recognized private revelations place this blow on the right side of the chest. Maria Valtorta herself, in the Poem of the Man-God, describes the scene thus:

"Longinus stands facing the Crucified One, studies his blow carefully and strikes. The broad lance penetrates deeply from below upward, from right to left. […] From the wound oozes much water and a thread of blood already tending to clot." — Maria Valtorta, The Gospel as Revealed to Me, vol. IX, chap. 609^[10]

The direction of the blow "from right to left" means: from the soldier's right toward his left, which corresponds, when striking the Crucified One face to face, to Christ's anatomical right side. The wound is therefore on the right. On the Shroud of Turin, by contrast, the observer clearly sees it on the left of the positive image (in the photographs of Secondo Pia, 1898, and of Giuseppe Enrie, 1931). This apparent discrepancy is not an anomaly: it is direct proof of the mirror inversion.

"On Enrie's positive photographs, the side wound appears on the left of the image — which corresponds, after correction of the mirror inversion, to the anatomical right fifth intercostal space." — Pierre Barbet, A Doctor at Calvary, 1950^[11]

Pierre Barbet locates the wound precisely at the right fifth intercostal space, a position confirmed by Robert Bucklin (the STURP's forensic pathologist) during his 1978 virtual autopsy and by Frederick T. Zugibe in The Cross and the Shroud (Angelus Books, 1988, pp. 122-128)^[12]. The sindonological consensus is complete.

The other converging markers: right cheekbone and "epsilon"

The lance-wound test does not stand alone. Two other major anatomical markers converge and confirm the mirror inversion.

The main swelling of the face. On the positive image of the Shroud face, one observes a voluminous swelling and a triangular mark under the eye, located on the observer's left. Anatomically, after mirror correction, this is Christ's right cheekbone. This right lateralization is confirmed by the STURP forensic pathologists and by the whole iconographic tradition (the servant of Annas strikes Christ in the face, and most Fathers place the blow on the right cheek)^[13].

The frontal flow "in epsilon shape". On Christ's forehead, one of the most famous blood flows, observed in detail by sindonologists, has the characteristic shape of a "reversed 3" or of the Greek letter epsilon (ε). This flow lies on the observer's left on the positive image. Anatomically, after mirror correction, this is Christ's right forehead. The "reversed" shape of the 3 is precisely what confirms the mirror effect: the original flow on Christ's forehead had the shape of a normal 3, which appears flipped on the imprint image^[14].

"The most prominent of these crown of thorns bloodflows is on the man's left forehead — shaped like a reversed "3", or the Greek letter epsilon (ε)." — Stephen E. Jones, The Shroud of Jesus: 2.5 The Bloodstains, theshroudofturin.blogspot.com, 2013^[15]

Three major anatomical markers thus all converge toward the same side of the image (the observer's left) and toward the same anatomical laterality (Christ's right). The mirror inversion is not one hypothesis among others: it is the only coherent framework able to unify all the data.

What this implies for the hands

Now on the Shroud, the hand visible on top, whose wrist with its typical bloody nail mark is clearly seen, lies on the same part of the image as the three preceding markers: on the observer's left. By the same mirror-correction operation, it therefore corresponds anatomically to Christ's left hand. And the visible mark — the subject of anatomical debate between Barbet (Destot's space) and Zugibe (deep palm, base of the metacarpal) — lies at the wrist or wrist base of Christ's left hand.

This is exactly the point that creates the difficulty with the dictation of 29 December 1943. Valtorta claims the reverse on both parameters: the right hand on top, and the nail at the wrist of the right hand. The table in the next section summarizes the situation.

Which hand covers the other on the Shroud?

On the positive image of the Shroud, the hand visible on top is the one whose wrist and back are clearly seen, crossed by a flow of blood coming out of the nail mark. This hand is positioned on the observer's left, on the same vertical line as the lance wound higher up. Anatomically, after mirror correction, it is therefore Christ's left hand which rests over the right hand.

This reading is confirmed by all reference sindonologists since Barbet: Robert Bucklin, Frederick T. Zugibe, John Jackson, Mario Latendresse (who produced the 3D Shroud Scope mapping from the Durante 2002 high-resolution photographs), Jean-Christian Petitfils (Tallandier, 2022), Giulio Fanti and Pierangelo Basso (University of Padua, ScienceDirect, 2016)^[16].

"The hands are crossed just below the umbilicus at the hip level with the left hand over the right one." — G. Fanti, P. Basso, Body Image Characteristics on the Shroud of Turin, ScienceDirect, 2016^[17]

Where is the visible wound: wrist or palm?

The wound visible on Christ's left hand (= the hand on top in the image) lies, according to sindonology:

• According to Barbet (1950, A Doctor at Calvary): in Destot's space, at the carpus — hence at the wrist^[18].
• According to Zugibe (1988, The Cross and the Shroud): at the base of the deep palm, between the 2nd and 3rd metacarpals — hence still broadly at the wrist or palm base, but slightly more distal than Barbet^[19].
• According to Mario Latendresse (Shroud Scope, 2002): on the high-resolution images, the mark itself clearly appears at wrist level, at the lower boundary of the forearm and the palm^[20].

In all cases, the visible mark lies at the wrist or at the immediate base of the palm, never clearly at the centre of the metacarpus in Valtorta's sense.

Valtorta / Shroud consistency table

To visualize the gap between the Valtortan claims and the observed image, here is the summary table of the three claims of the dictation of 29 December 1943.

Of the three claims, two are in direct discordance with the mainstream sindonological verdict. The third (nail at the wrist of the right hand) can be neither confirmed nor refuted, since the right hand, according to the Shroud, is hidden by the left hand.

📖 See the specialized article: Was Jesus nailed through the palms or through the wrists? — for the complete Barbet / Zugibe debate file and the harmonious theory compatible with Anne Catherine Emmerich.

Contradiction 1 — Which hand is on top

This is the most direct contradiction. Valtorta claims the right on top, the Shroud shows the left on top. Since one cannot be both A and non-A, a choice must be made among four options:

1. Valtorta is right and the whole of sindonology has been mistaken for a century.
2. Sindonology is right and Valtorta was mistaken on this point.
3. The Shroud is not authentic, so nothing obliges it to agree with a mystical dictation.
4. The word "covers" in Valtorta has a different meaning from the naive reading (linguistic interpretation).

Option 3 is excluded: Valtorta herself, in several other passages, affirms the authenticity of the Shroud ("the Shroud on which the sweat of my death printed the mark of my sorrow", Notebooks of 1943, 22 July 1943; "there lies the history of my Passion written with the ink of my divine Blood on the linen", Notebooks of 1943, 23 October 1943)^[21]. It would be strange to dismiss the Shroud in order to save Valtorta on this point, when Valtorta affirms and defends that same Shroud.

Option 4 (linguistic interpretation) is hardly plausible: the dictation is written in ordinary modern Italian, and the verb "ricoprire" (to cover) admits no ambiguity. "La mano destra ricopre la sinistra" means strictly "the right hand covers the left hand". No serious Valtortan commentator has upheld any other reading.

There remain options 1 and 2. Option 1 would suppose that Barbet, Bucklin, Zugibe, Jackson, Petitfils, Fanti, Latendresse and all Catholic sindonologists (often themselves favourable to the Shroud's authenticity) had all made the same lateral-reading error. Possible, but highly improbable, especially given the perfect convergence with the other markers (lance, cheekbone, epsilon). Option 2 — an inaccuracy by the visionary on this point — is intellectually the simplest and most economical: it corresponds to the human mediation known to the theology of private revelations, and described by the Dicastery in 2025 under the formula of "literary forms".

Contradiction 2 — Location of the nail in the visible hand

If the visible hand on the Shroud is anatomically the left (according to sindonology), and its mark is at the wrist or at the immediate base of the palm, then the left hand is nailed through the wrist. Yet Valtorta claims exactly the reverse: the left hand is nailed "into the centre of the palm, between two metacarpal bones", and it is the right hand that is at the wrist.

This contradiction is independent of the first: even supposing, out of interpretive charity, that Valtorta had inadvertently swapped "right" and "left" when speaking of the relative position of the hands, the absolute location of the nails in each hand would remain incompatible with the Shroud. The Shroud shows a mark at the wrist, not in the deep palm in Valtorta's sense.

Contradiction 3 — The "stretched" arm and arm length

Valtorta further claims a fascinating detail shared by several mystics: Christ's left arm was stretched with a rope until the tendons tore, because the hole in the cross had been badly measured. This datum converges with the vision of Anne Catherine Emmerich (The Dolorous Passion, chap. XXXIV), who adds the effective dislocation of the shoulder^[22].

If this mystical detail is anatomically true, then Christ's left arm should appear longer than the right arm on the Shroud image. And this anomaly should be measurable.

Yet the two reference scientific studies on the comparative length of the arms on the Shroud — Ercoline-Downs-Jackson (1982) and Gilbert R. Lavoie (1989) — both conclude that the upper arm (on the positive image) appears longer than the lower arm^[23][24]. The upper arm, on the positive image, being anatomically Christ's left hand (by the mirror effect), this coincides precisely with the Valtortan prediction and with Emmerich's vision. But only on condition of accepting that the visible hand on top is the left hand.

This is a deeply interesting point: the scientific studies' datum on arm length would confirm Valtorta on the stretching of the left arm — on condition of accepting the standard sindonological interpretation of laterality. Yet that same interpretation contradicts Valtorta on the relative position of the hands. The dictation presents here an internal tension: for the stretching argument to hold, the visible hand must be the left; but Valtorta claims it is the right.

Lavoie strongly qualifies the scope of the observation: according to him, the difference in length between the two arms is only an optical illusion due to distortions in the drape of the burial cloth over the body, not a real anatomical difference.

"The difference in the length of the two arms on the Shroud of Turin is an optical illusion. When the distortions of the drape are taken into account, the two forearms measure as equal in length." — Gilbert R. Lavoie, The Difference in the Length of the Arms is an Optical Illusion, Shroud Spectrum International no. 30, 1989^[25]

Ercoline and Jackson reach a similar conclusion: the measured lateral deformations correspond to those expected of a shroud falling naturally over a reclining body. No major anatomical anomaly^[26]. Lorenzo Ferri (1902-1975), the Italian sculptor who produced a three-dimensional clay reconstruction in the 1950s, defended on the contrary the thesis of a real difference of about 4 to 8 cm, which he interpreted as the signature of a dislocation of the right shoulder (not the left)^[27]. His position is a minority one in contemporary sindonology, but it survives among defenders of Emmerich's vision.

In short: the stretching argument, to carry any weight in the debate, presupposes a standard sindonological reading (visible hand = left). But that standard reading contradicts the Valtortan dictation on the relative position of the hands. The anatomical detail therefore contributes less to reconciliation than it seems.

Hypothesis A — The Shroud image is not mirrored

This is the most radical defence, explored by some Valtortan apologists. It runs: "The Shroud image is in direct view, not mirrored. The visible hand on the observer's left is therefore indeed Christ's right hand, which confirms Valtorta."

This hypothesis has a local advantage: it resolves contradiction 1 (relative position of the hands). But it immediately creates three others, far more serious:

• The lance wound would end up on Christ's left side — contradicting the Gospel, the unanimous tradition, and Valtorta herself, who describes the lance entering "from right to left" from the soldier toward Christ's right side.
• The swollen cheekbone would be on the left cheek — contradicting the traditional iconography.
• The frontal flow "in epsilon shape" would be on the left forehead — with no particular significance, since the reversed 3 would no longer exist as a mirror effect.

At the price of half a sentence of the dictation of 29 December 1943, this hypothesis sacrifices three of the most solid converging results of sindonology. Taken seriously, the three converging markers (lance, cheekbone, epsilon) leave no room for this reading: it cannot be maintained.

Hypothesis B — A mysterious double inversion

A subtler variant: "The Shroud image supposedly underwent a double inversion (for example, the image would form from inside the shroud, pass through the cloth, and be visible from the other side). So in the end it is like a non-mirrored direct view."

This hypothesis is physically unfounded. The Shroud image is superficial: the altered fibres are only those on the side that touched the body, never those on the opposite side. This is one of the STURP's most solid results: no image passed through the cloth; the visible image is strictly on the inner face (contact side)^[28]. Any hypothesis of the cloth being "seen through" is refuted by direct physical examination of the Shroud since 1978.

Above all, this hypothesis meets exactly the same problem as hypothesis A: it destroys consistency with the lance, the cheekbone and the epsilon. No gain in internal consistency.

Hypothesis C — Ferri and arm length

A hypothesis internal to sindonology: follow Lorenzo Ferri's reading rather than Lavoie's and Ercoline's. The upper arm would then anatomically be the right arm (not the left), because it is the right arm that was dislocated and lengthened.

This hypothesis has two major problems:

1. It contradicts mainstream sindonology on the laterality of the hand on top. Yet this laterality does not depend on the choice between Ferri and Lavoie on arm length — it is established independently, by the mirror effect + the three-marker test. Ferri does not propose another lateral reading; he proposes another length measurement. These two questions are distinct.
2. It contradicts Valtorta herself, who claims that it is the left arm that was stretched. So even following Ferri, the dictation is not reconciled thereby: the difficulty merely shifts.

Hypothesis C therefore turns against itself: it forces a choice between Ferri (hence against Valtorta on the stretching) or Valtorta (hence against Ferri on the laterality of the lengthening).

Hypothesis D — The visionary's human mediation

The most sober and most economical hypothesis: the dictation of 29 December 1943, like other passages of the Notebooks and the Poem, bears the trace of the visionary's human mediation. The anatomical account of the Crucifixion, considerable and impressive as it otherwise is, contains on this precise point a claim that does not match the observed image, most likely stemming from Valtorta's visual memory of the Shroud.

This hypothesis is convergent with the position of the Dicastery for the Doctrine of the Faith in its communiqué of 22 February 2025: the Valtortan dictations are "not of supernatural origin" in the strict sense, but must be received "as literary forms"^[29]. It does not require rejecting the whole work, which contains remarkable theological and historical intuitions. It simply invites us not to absolutize anatomical details against the converging sindonological sciences.

It is the simplest hypothesis (Ockham's razor), the most respectful of mainstream sindonology, the most consistent with the current canonical status of the Valtortan work, and the least costly intellectually.

Anne Catherine Emmerich: compatible with the Shroud

Blessed Anne Catherine Emmerich (1774-1824), stigmatized Augustinian nun beatified on 3 October 2004 by Saint John Paul II, received for her part very detailed visions of the Crucifixion, transcribed by the poet Clemens Brentano and published under the title The Dolorous Passion of Our Lord Jesus Christ (Sulzbach, 1833; Téqui edition 2005)^[30].

Emmerich's account describes the nailing of the right hand in the palm (not at the wrist, against Valtorta), then the violent stretching of the left arm with ropes until the dislocation of the shoulder, because the hole in the cross had been badly measured. The nail is then driven into the left hand in a position naturally displaced toward the wrist or carpal area due to the forced extension of the arm.

"They perceived that the other hand could not reach the hole bored in the left arm of the cross; then they tied ropes to the left arm of Jesus, and, bracing their feet against the cross, they pulled it until the hand reached the place of the nail. His arms were dislocated, his chest was convulsively heaved, and his whole body was in anguish." — Bl. Anne Catherine Emmerich, The Dolorous Passion, chap. XXXIV, Téqui ed., pp. 229-230^[31]

Observe carefully: Emmerich's account is mechanically compatible with what the Shroud shows. The right hand is nailed in the palm first (normal anatomical configuration); it is hidden behind the left hand in the Shroud position. The left hand is pulled with a rope and nailed in the wrist area because of the forced extension. On the Shroud, it is precisely the left hand that is visible on top, with its mark at the wrist. Emmerich agrees with the Shroud; Valtorta does not.

This comparison does not disqualify Valtorta — Emmerich is no more a dogmatic norm — but it shows that the difficulty raised by the dictation of 29 December 1943 is not a problem common to all mystics: it is a difficulty proper to this precise passage of Valtorta.

Saint Bridget of Sweden

Saint Bridget of Sweden († 1373), in her Revelations (book I, chap. 10), reports having seen Christ's hands nailed "where the bone was strongest"^[32]. The wording is neutral as between the wrist and the deep palm, since both areas offer satisfactory bony resistance (carpus for the wrist, metacarpals for the deep palm according to Zugibe). But it contradicts neither of the two anatomical scenarios compatible with the Shroud.

Padre Pio and the stigmata: light shed

Saint Padre Pio (1887-1968), Capuchin stigmatized since 20 September 1918, presents extensively documented stigmata. Several physicians (Luigi Romanelli, 1918; Georg Festa, 1920; Ezio Saltamerenda, 1954) examined his wounds and noted their constant position in line with the index and middle fingers, in the deep palm, between the second and third metacarpals^[33]. Frederick Zugibe stresses that this position corresponds exactly to his own anatomical theory of the deep palm — as opposed to Barbet's wrist^[34].

If one follows the harmonious theory developed in the specialized article Palms or wrists — right hand in the deep palm + left hand pulled toward the wrist according to Emmerich — then Padre Pio's stigmata on the palms correspond to Christ's right hand (the first nailed, in the palm), and the rarity of wrist stigmata corresponds to the left hand (rarer cases in mystical history). This configuration is compatible with the Shroud. It is not compatible with the Valtortan dictation, which places the palm on the left side and the wrist on the right.

Claims of authenticity

To measure the scope of the problem correctly, it must be stressed that Valtorta affirms the authenticity of the Shroud of Turin in several other dictations, without the slightest ambiguity. This excludes any hypothesis that she might, by design or distrust, have wanted to introduce a detail contradicting the Shroud in order to dismiss it.

"The relics of my life and of my death: the house of Nazareth […] and the Shroud on which the sweat of my death printed the mark of my sorrow, suffered for humanity." — Jesus to Maria Valtorta, The Notebooks of 1943, dictation of 22 July 1943^[35]

"This Piedmont, where there lies a testimony of God in no way inferior to that of the Mosaic Tabernacle […] there lies the history of my Passion written with the ink of my divine Blood on the linen which pity offered to wrap my nakedness as a victim." — Jesus to Maria Valtorta, The Notebooks of 1943, dictation of 23 October 1943^[36]

The French publisher explicitly notes (note 202) that this is the "Holy Shroud, kept in the Cathedral of Turin". Valtorta thus defends the Shroud as a major relic "in no way inferior to the Mosaic Tabernacle" — a formula placing the Shroud at the highest rank of material testimonies of Revelation.

Valtortan attempt at describing the imprinting process

In the Notebooks of 1944, Valtorta also receives explanations about the chemical process of the cloth's imprinting: Christ's kidneys no longer functioning in the agony, a particular sweat laden with urea and salts supposedly impregnated the cloth and caused the image. This explanation is an old one and has been discussed by sindonologists: the precise chemical mechanism remains debated, but the localized-oxidation component was confirmed by the STURP. The Valtortan description is neither absurd nor refuted, but it does not settle the question of the image's formation^[37].

Synthesis of the Valtortan position on the Shroud

Valtorta therefore holds simultaneously:

• The Shroud is authentic;
• On this Shroud, the right hand covers the left;
• The nail positions are right wrist + left palm.

The second and third propositions, as seen, are in discordance with mainstream sindonology. The first proposition (authenticity) is unaffected by this discordance: one may affirm the Shroud's authenticity while recognizing that a given mystical dictation on a given anatomical detail is inaccurate.

To synthesize the whole case transparently, it is useful to present side by side the two rival readings the Shroud image can receive, and to confront them point by point with all available data: Gospel, iconographic tradition, sindonological science, compatible mystics, comparative anatomy. This grid is the practical heart of the article: a hurried reader may stop here and find the essentials.

Definition of the two readings

Reading A — Standard sindonology (mirror effect). The Shroud image is a contact imprint which necessarily produces a lateral inversion with respect to the real body. On the positive image (Pia 1898, Enrie 1931), the hand visible on top, on the observer's left, therefore corresponds anatomically to Christ's left hand. The right hand, underneath, is hidden. This is the reading defended by Barbet, Bucklin, Zugibe, Jackson, Petitfils, Fanti, Latendresse and the whole of mainstream sindonology since 1950^[38].

Reading B — Strict Valtorta (direct view without mirror). The Shroud image is read as a non-inverted direct view, as required by the dictation of 29 December 1943 ("the right hand covers the left hand"). On the positive image, the hand visible on top, on the observer's left, then corresponds anatomically to Christ's right hand. The left hand, underneath, is hidden. This reading is intellectually mandatory if the Valtortan dictation is taken literally, but it is defended by no reference sindonologist^[39].

Complete comparative grid

Each row of the table evaluates one observed or attested fact. The corresponding column receives ✅ (consistent), ❌ (discordant) or 🟠 (ambiguous). The final total gives a measure of the degree of consistency of each reading.

Commented reading of the table

On the three converging markers (lance, cheekbone, epsilon). These three anatomical elements all lie at the same place in the image (the observer's left on Enrie's 1931 positive photograph) and all designate, according to the unanimous iconographic tradition and according to Valtorta herself, Christ's anatomical right side. This is exactly the expected result of a mirror-reversed image. No non-mirror explanation has been proposed by any sindonologist to make these three markers converge without lateral inversion. Reading B must therefore, to remain consistent, either deny the convergence (but it is measurable and confirmed by all scientific groups) or deny the tradition (but Valtorta herself confirms it).

On the physical mode of image formation. The STURP, after five days of direct examination of the Shroud in October 1978, established experimentally that the image is strictly superficial (limited to the outer fibrils on the side in contact with the body), that it encodes three-dimensional information (intensities are proportional to body-cloth distance) and that it could only have been produced by contact or very-short-range emanation. Any hypothesis of a non-mirrored direct view contradicts this fundamental experimental result, which has never been refuted in forty-five years.

On the one point where Reading B seems to score. The nail mark visible on the upper hand does indeed lie at the wrist (Destot's space according to Barbet) or at the immediate base of the deep palm (according to Zugibe). If this upper hand were Christ's right (Reading B), this would literally coincide with the Valtortan dictation ("right hand at the carpus"). But this local gain collapses as soon as one notices:

• Under Reading A, the wrist mark corresponds to Christ's left hand, which was "pulled with a rope" according to Emmerich (and according to Valtorta herself, who describes the stretching of the left arm). This hand, stretched to dislocation, could no longer fall back into the hole intended for the palm: it naturally ends up nailed toward the carpus or the immediate palm base. Reading A therefore explains perfectly, via Emmerich, why the visible mark is at the wrist.
• Under Reading A, Zugibe proposes an alternative to Barbet in which the mark is rather at the base of the deep palm (between the 2nd and 3rd metacarpals). The exact anatomical area remains debated to within 1-2 cm, but it is compatible with both nailing scenarios and with Padre Pio's documented stigmata.
• Lorenzo Ferri himself, an ardent defender of a different lateral reading, holds that the visible hand is the left (not the right) and that it is nailed in the palm (not at the wrist). His position therefore paradoxically reinforces Reading A on laterality, while remaining a minority view on arm length.

Overall score. Reading A (sindonological) totals 10 consistencies against 1 contradiction (the strictly read Valtortan dictation, the only point it does not reconcile). Reading B (strict Valtortan) totals 2 consistencies (dictation + wrist mark), 8 contradictions and 1 ambiguity. The gap is clear, and no internal hypothesis closes it entirely. The most sober reading is that the dictation of 29 December 1943, taken literally on the relative position of the hands, would not accommodate the actual image of the Shroud. This is precisely the typical case of human mediation addressed by the Dicastery for the Doctrine of the Faith in its communiqué of 22 February 2025, asking that Valtorta's work be received "as literary forms".

Why this finding does not invalidate all of Valtorta

This finding of discordance concerns half a sentence of the dictation of 29 December 1943 and its immediate anatomical consequences. It does not concern:

• The whole Valtortan corpus, whose Poem of the Man-God contains passages of literary and theological grandeur attested by Bl. Allegra, Fr. Roschini and Msgr. Lattanzi.
• The other dictations on the Passion (right side pierced by the lance, stretching of the left arm, bloody sweat at Gethsemane, etc.), which remain compatible with tradition and with the Shroud.
• The authenticity of the Shroud itself, which Valtorta affirms and defends in several other dictations as a relic "in no way inferior to the Mosaic Tabernacle".
• Valtorta's real mysticism, which can coexist with a human mediation bringing its own approximations on certain anatomical details.

It is the perfect example of what classical theology calls human mediation in private revelations: the visionary receives a supernatural grace, but its formulation passes through her memory, imagination, prior knowledge and limits — which may introduce inaccuracies on observable points.

This is also what the discernment of the three possible sources, the devil, the imagination and God, calls to mind. Here, the criterion of the fruits rules out the diabolical source: a work that leads towards prayer, peace and the love of God does not come from the enemy. There is therefore necessarily a part of divine inspiration, mixed with the visionary's human make-up. What proportion of divine inspiration? The question remains open. In every case, it is a work that does good to the soul, and that is what matters most.

A typical case of human mediation

The tension documented in this article is precisely the kind of difficulty addressed by the Dicastery for the Doctrine of the Faith (DDF) in its communiqué of 22 February 2025.

"The alleged 'visions', 'revelations' and 'communications' contained in Maria Valtorta's writings, or in any case attributed to them, cannot be considered of supernatural origin, but must be considered as literary forms which the author used to recount, in her own way, the life of Jesus Christ." — Dicastery for the Doctrine of the Faith, communiqué of 22 February 2025 (official French text, vatican.va)^[52]

A strictly supernatural revelation should not contain an anatomical error on an observable detail. A literary work carried by a bedridden visionary, who never saw the Shroud of Turin in person, and who could only read partial descriptions of it or see approximate images, may contain this type of inaccuracy — without invalidating the whole.

This reading converges with the position of Valtorta's principal historical academic supporters. Bl. Gabriele M. Allegra, OFM, translator of the Chinese Bible and Franciscan theologian beatified in 2012, describes the work in these terms:

"A masterpiece of Italian religious literature, and perhaps of world Christian literature." — Bl. Gabriele M. Allegra, Il mio incontro con l'opera di Maria Valtorta, Bollettino Valtortiano no. 6, September 1972^[53]

Allegra speaks of a literary masterpiece of the highest rank, not of a fifth Gospel. Father Gabriele M. Roschini, OSM, professor of Mariology at the Marianum, recognizes solid theological intuitions in Valtorta, while distinguishing what belongs to inspiration from what belongs to human composition^[54]. Msgr. Ugo Lattanzi, dean of the Lateran theology faculty, phrases his 1951 assessment in similar terms:

"Truths expressed with a fullness exceeding the ordinary capacities of a writer." — Msgr. Ugo Lattanzi, handwritten assessment addressed to Msgr. Fontevecchia, 1951^[55]

Lattanzi's formula recognizes an unusual gift of writing without excluding imperfections of detail — which corresponds exactly to the status of the dictation of 29 December 1943.

Beyond these three voices, the documented ecclesiastical supports deserve to be named, each for what it is: a testimony or a gesture, never an act of the Magisterium. The audience with Pius XII on 26 February 1948, on the sole testimony of Fr. Corrado Berti, who encouraged the priests to publish without pronouncing on the origin of the work^[56] ; Msgr. Giovanni Battista Montini, the future St. Paul VI, giving a complete set of the work to the seminary of Milan when he was archbishop, according to the seminary's archives^[57] ; Msgr. Alfonso Carinci as early as 1952, and his exact formula "Non c'è nulla di contrario al Vangelo"^[58] ; the reported testimony of St. Padre Pio through Elisa Lucchi^[59] ; St. Teresa of Calcutta carrying away a volume of the Poem, according to Fr. Leo Maasburg^[60] ; the letter of encouragement from Pope Francis to the president of the Valtorta foundation on 24 February 2024, reported by the foundation^[61]. The Edifiant.fr page, section on ecclesiastical supports, serves as an index to the underlying sources, never as a sole source^[62]. The full dossier of these supports, and the evolution of Cardinal Ratzinger's position, are to be found in the article Answers to objections about the work of Maria Valtorta.

What this does not call into question

Recognizing that the dictation of 29 December 1943 contains an anatomical claim that does not match the observed image does not call into question:

• The authenticity of the Shroud of Turin itself, which rests on an independent converging scientific case, separate from any private revelation (cf. the article The Holy Shroud of Turin).
• The whole Valtortan corpus, which contains many pages of remarkable theological beauty and soundness.
• The possibility that Valtorta received authentic mystical graces: real mysticism can coexist with a human mediation that colours and sometimes inflects the message.
• The lawfulness of reading Valtorta: the work was placed on the Index in 1959 ; the Index was abolished wholesale in 1966 ; the letter from Cardinal Ratzinger of 31 January 1985 judged the recommendation of the work "inopportune" ; the Dicastery's communiqué of 22 February 2025 asks that the writings be received "as literary forms". No prohibition to read is in force: the Roman position asks for prudence, not prohibition.

Receiving Valtorta in a balanced way

The right use of Valtorta's work, in light of this specific case as of the whole 2025 DDF communiqué, seems to be the following: recognize the work's literary, meditative and theological value; do not use it as an authoritative historical source on precise material facts (anatomy of the Crucifixion, geography, dating) which fall to the profane sciences; do not make it a fifth Gospel in the sense of Valtorta becoming the criterion against which other sources (Gospel, Tradition, Magisterium, sindonological sciences) would be judged.

This is exactly the status assigned to the work by Msgr. Tettamanzi's commission (CEI, 1992), then by the DDF (2025): reading is permitted, literary inspiration recognized, but the claim to strict supernatural revelation is suspended. The dictation of 29 December 1943 provides, on its own, an eloquent practical case of what this prudent reading means.

This remains secondary

To say it by way of conclusion: the problem of the covering hand remains secondary. It concerns a physical detail of the Shroud, not doctrine, nor the fruits, nor the spiritual life the work awakens. Perhaps something to bring down our pride and our human intelligence: we would like everything to be measurable and concordant, and half a detail of dictation is enough to remind us otherwise.

The tension is real, it has its page, it is documented; it settles neither the origin of the work, nor its value for the soul. A Catholic who reads Valtorta finds matter for prayer there; a demanding reader finds a difficulty of detail, and nothing that forces a choice between the Shroud and the Gospel. What matters most is elsewhere: it is a work that does good to the soul, and that is what matters most.
