This refined marble statue, depicting a young man, probably a prophet, is attributed to the young Donatello (ca. 1404-1409). It comes from the right pinnacle of the tympanum of the Porta della Mandorla, on the north side of the Cathedral, where it was paired with another similar statue, sculpted by Nanni di Banco. Both were part of the rich decoration of the portal. The statue is made of white marble, sculpted in the round, and portrays a smaller-than-life-size young man in an upright, striding pose. He is dressed in ancient-style garments, with a crown of leaves woven into his thick hair, and his resolute gaze directed toward the horizon. The attribution to the young Donatello is suggested both by its stylistic quality—evidencing a knowledge of classical statuary, excellent plastic mastery, and a strong ability to render psychological depth—and by its resemblance to the so-called Marble David, executed by Donatello for the Cathedral in the same years (now in the Bargello Museum). Identifying the figure with certainty is more challenging. Several clues suggest he may be a prophet. First, his attire is in the ancient style, and his companion holds a scroll, a common attribute of prophets. Their position in relation to the tympanum is also significant, as it features Marian-themed decorations in bas-relief and mosaic. According to iconographic tradition, prophets and sibyls are placed in the frames and peripheral areas of narratives about Mary and Christ, as Christian exegesis reinterpreted their prophecies in light of the Gospel. It is impossible to determine his identity with certainty or to explain his youthful appearance. However, the vegetal crown, the forward movement of his leg and gaze, and his ephebic features have led some scholars to hypothesize that he was originally conceived as an Annunciation angel and later repurposed.
