Work considered by Bronzino in the early twentieth century and subsequently assigned to Alessandro Allori, it is then attributed to an anonymous Frenchman, the latter hypothesis being considered the only correct one. The young man in armor with his hand resting on his helmet has a posture that mirrors the much more famous portrait of Cosimo I de 'Medici made by Bronzino around 1545 and replicated in numerous copies. Precisely the position of the character could suggest the hypothesis that it may be a pendant. Interesting is how the shape of the plumed headdress and the armor with golden parts and rivets also of gold are treated, but with a systematic abundance of decorations and figures that today are enigmatic. The seal under the schooner of the armor depicts what looks like a Minerva inside a laurel wreath supported by two winged characters. Below, on the belly, a man in armor with a plumed helmet, sword at his side and spear. Precisely the armor, so rich and complex, together with the bearing of the character, introduces the theme of the transformation of the figure of the fifteenth-century gunman, who in the sixteenth century tends to become a man of the court and confidant, for example as the well-known Baldassare Castiglione (Casatico, 1478 - Toledo, 1529).
