Location details
“The original chapel, which was very small, was enlarged in the 14th century with the addition of the dentil-decorated section; in the 15th century, the portico was added, which was later filled in. The decoration of the portico’s vaulted ceiling was executed by the school of the Biazaci brothers and depicts, across the four ribs, the story of Saint Sebastian, commander of Diocletian’s First Cohort, who was martyred in the 4th century”.
The painting on the four ribs is divided into seven scenes (the central one is unique, dedicated to the martyrdom), which narrate the saint’s life; the story is taken from Jacopo da Varagine’s Golden Legend. Of particular intensity is the second scene, where the saint’s face, rendered with great sensitivity, reveals the hand of Tommaso Biazaci. The cartouches in the vernacular are typical of this chapel, which differs from the Chapel of St Stephen, where the cartouches are in Latin.
