Focus on Bearded Slave and analyze the Description and style.
The Bearded Slave is the most finished of the Florentine Prigioni and gets his name from his thick, curly beard. The way his muscular torso twists indicates a deep knowledge of anatomy, typical of the best works of Michelangelo; his legs, slightly bent and separated, are covered by a band of fabric. His right arm is raised to hold his bent head, while his left hand remains unfinished, but seems to hold the band of fabric.
The whole surface retains many traces of the various chisels and scrapers used on the sculpture. Along his hips there is a repaired fracture, whose cause is unknown.
Its unfinished state creates an extraordinary energy (already noted by Bocchi in 1591), with the figure caught in a sort of primordial act of freeing himself from the cage of the rough stone, an epic battle with the forces of chaos. The iconographic meaning of the figures was probably linked to the motif of the captivi in Roman art, and indeed Vasari identified the Prigioni as personifications of the provinces controlled by Julius II. For Condivi, however, they symbolised the Arts, made "prisoners" by the death of the pontif. Other scholars have made proposals of a philosophical/symbolic character or connected to the artist's personal life and his "torments".
