Because the bent proper right arm of this spear-bearing figure is repeated about a centimeter to the right, and the contour lines and forms are rendered with great precision, it is evident that this drawing is a worked-up copy. It replicates the lower left hand corner of Michelangelo’s Martyrdom of St. Peter (1545-1550, The Vatican), a fresco in the Cappella Paolina, in which the artist explored a variety of emotional reactions to the saint’s martyrdom. Interesting, however, is the fact that the copyist did not select any of the more emotionally compelling figures; rather, he opted for the sculptural, strongly muscles figures that were Michelangelo’s trademark.
