Statue in white marble, attributed to Nanni di Banco and dated around 1404-1409, depicting a smaller-than-life size young adolescent, traditionally identified with a Prophet and coming from the right pinnacle of the tympanum of the door of the Cathedral called "della Mandorla (side north), where it was a companion to a second similar one, referring to Donatello and with the one included in the iconographic program with a Marian subject of the decorations of the portal.

The statue represents a young man with a full, oval face, large eyes, small nose, tight lips and hair gathered high. He wears a shirt tightened at the hips with a belt, and a tunic that covers his legs with wide drapes down to his feet, without shoes. The figure is imagined in a standing pose balanced on the left leg, the left hand at the side and the right hand holding a small unrolled scroll.

The attribution to Nanni di Banco is almost unanimous: Donatello's youthful and less talented companion, he was the author of various parts of the portal, including the large relief of the tympanum with the Assumption of Mary. The iconographic identification with a prophet is established by the attributes of the ancient dress, the bare feet and the scroll with the prophecies open in the right hand, but it remains difficult to establish the exact identity and explain the young age.

The presence of two prophets at the sides of the representation of the Assumption of Mary was fully part of the iconographic tradition: prophets and sibyls were often placed in these corollary positions with respect to the stories of Mary and Christ, because the Christian tradition had reread their prophecies in the light of New Testament.
