 Such a complex disarray of figures was rare in Florentine art, where it would usually only be found in images showing either the Massacre of the Innocents or the Torments of Hell.The relief treatment, in which some of the figures are boldly projecting, may indicate Michelangelo's familiarity with Roman sarcophagus reliefs from the collection of Lorenzo Medici, and similar marble panels created by Nicola and Giovanni Pisano, and with the figurative compositions on Ghiberti's Baptistry Doors.The composition of the "Battle of Cascina" is known in its entirety only from copies, as the original cartoon, according to Vasari, was so admired that it deteriorated and was eventually in pieces.
