Marble statue attributed to the young Donatello (ca. 1404-1409), depicting the figure of a young adolescent, traditionally identified with a prophet and coming from the right pinnacle of the tympanum of the Cathedral Door known as the Mandorla (north side), where it was a companion of another similar one, by the hand of Nanni di Banco and where it was an integral part of the rich Marian-themed decoration. The statue is in white marble, worked in the round and depicts a smaller-than-life size young man, in an upright and walking pose, with old-fashioned clothes, with a crown of leaves among his thick hair, his determined gaze turned towards the horizon. The attribution to the hand of the young Donatello is suggested both by the stylistic quality, which shows knowledge of classical statuary, excellent plastic mastery and a marked capacity for psychological rendering, and by the resemblance to the so-called marble David created by Donatello for the Cathedral in the same years (now at the Bargello). Character identification is more difficult. Some clues suggest that he is a prophet. First of all, he is dressed in the old style, and his companion also carries a scroll, an attribute of the prophets. Their position in relation to the tympanum is also significant, which bears decorations (bas-relief and mosaic) with a Marian theme: prophets and sibyls by iconographic tradition are in the frames and in the peripheral areas of the stories of Mary and Christ, because Christian exegesis he reinterpreted the prophecies precisely in the light of the Gospel. It is impossible to identify it exactly and explain its age. However, the vegetal crown, the forward movement of the leg and gaze, the ephebic appearance, have led some scholars to hypothesize that it is an angel of the annunciation, subsequently adapted.
