Abstract
Andrea del Verrocchio was a leading artist in Renaissance Italy. Best known today as the teacher of Leonardo da Vinci, Verrocchio was a celebrated artist in his own right. Born in Florence c. 1435 to a family of artisans and laborers, Verrocchio spent most of his career in that city. He died in Venice in 1488, two years after he had moved there to make a bronze equestrian monument of the mercenary general Bartolommeo Colleoni. Verrocchio worked in an unusually wide variety of media. In sculpture he produced works in marble, wood, bronze, terracotta, and wax. He was also a draftsman, painter, and goldsmith. Most studies on the artist tend to focus on his art in sculpture and few consider his work in different media in dialogue. Yet the artist frequently used the tools and techniques from one medium in another. A closer look at Verrocchio’s tendency to work between and across media reveals an artist who is among the most experimental in 15th-century Florence, itself a major European center of artistic innovation. Verrocchio influenced many of the leading artists of the next generation, especially painters, some of whom trained with him. These included Leonardo da Vinci, Pietro Perugino, and Domenico Ghirlandaio, among many others. Verrocchio initiated many formal, stylistic, and technical innovations that were taken up by artists of the next generation and in succeeding centuries. His Christ and Saint Thomas shows the figures in dynamic and carefully choreographed poses. Thomas is positioned on a step outside the niche in which Christ is placed and turns to reach forward as if to touch Christ’s wound but does not. The careful placement of the figures in relation to each other and to the niche around them anticipates formal developments taken up by Baroque artists, such as Gianlorenzo Bernini. Verrocchio’s Putto with a Dolphin has an equally dynamic pose, with the putto positioned so that it spirals around a central axis, its twisting body inviting the viewer to move around it. This pose came to be known as figura serpentinata (literally “serpentine figure”), a compositional device of enormous influence adopted by leading artists of the sixteenth century, including the painter Leonardo and the sculptor Giambologna. Verrocchio recognized the tonal potential for drawing in black chalk and used it to create areas of sfumato (areas of smokiness) in his drawings, a technical innovation commonly attributed to his pupil Leonardo.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
