Giampietrino and The Painting: Convergences and Divergences
The versions attributed to Giampietrino show a compositional proximity to The Painting that is too close to be accidental. The decisive point lies not only in the overall impression, but in the comparison of the structural lines, examined more precisely on the Shared Cartoon page.
This relationship is clarified by the derivation of Giampietrino’s Christs from Leonardo’s Venice Drawing, acknowledged by several historians and presented on the Art Historians page. The Painting belongs to the same field of reference, but the most significant differences appear elsewhere: in the X-ray image, the structure of the cross, the halo, certain morphological details and, more broadly, in the logic of execution.
Compositional and Measurement Convergences
- Very close compositions, despite the addition of a figure in The Painting;
- Similar dimensions and largely concordant tracings;
- Strong indication of a shared cartoon;
- Derivation of Giampietrino’s Christs from the Venice Drawing, acknowledged by art historians;
- The London and Budapest versions would depend on the same cartoon, according to the National Gallery, London.
Structural, Technical and Morphological Divergences
Although the works belong to the same prototype, they do not proceed in the same way. Several material and formal indications show that The Painting follows a distinct logic of execution.
X-ray: Different Contrasts and Execution
The X-ray image marks a first clear difference. In the London and Budapest versions, the image of Christ and the cross remains more diffuse. That of The Painting is more legible and shows more clearly the areas rich in lead white.
It also reveals reworkings in the forehead and beard, interpreted as pentimenti made during execution.

Technical Divergences
Spolvero: in The Painting, the presence of spolvero attests to a structured preparatory transfer. No comparable device is documented, in the present state of observation, for the versions attributed to Giampietrino.
Pentimenti: infrared imaging of The Painting reveals several structural pentimenti, absent or less legible in the compared versions.
Painting technique: according to the technical data cited in the study, the technique of The Painting does not correspond to Giampietrino’s known practice.

Morphology: Localised but Significant Differences
The general structure of the head remains close, but certain details cease to coincide. Two points are particularly revealing: the forearm and the parting of the hair.
In The Painting, the forearm appears more tense and more strongly constructed. The parting of the hair remains consistent with a three-quarter view; in Giampietrino, it tends towards a more frontal construction.

Halo: A Secondary Addition in The Painting
The halo constitutes a clear divergence. In The Painting, it was added a posteriori. In Giampietrino’s versions, by contrast, it was present from the outset.
See also: the dedicated page “Halo: Addition and Impact”.
Assembly of the Cross: A Solution Specific to The Painting
The assembly of the two arms of the cross does not follow the same logic. In The Painting, the short arm is placed beneath the long arm. In the compared versions by Giampietrino, the arrangement is reversed. The study concludes that The Painting is the only composition in the group to present this configuration.

Wood Grain: An Inverted Motif
Multispectral images make it possible to observe, around Christ’s head, wood-grain lines that are now almost erased. This area was partially repainted, most probably when the halo was added. In the upper part, however, the direction of the grain observed in Giampietrino’s versions is reversed in relation to that of The Painting.

Scope and Limits of the Comparison
The Painting and the versions attributed to Giampietrino very probably depend on the same prototype. But the differences observed in the X-ray image, the halo, the assembly of the cross and the wood grain exclude any simple assimilation: compositional proximity does not imply identity of execution.
