A unique bas-relief, which might be the first known self-portrait of Michelangelo, has emerged from a private collection, art historians announced in Florence this week.
The sculpture, a white marble round work attached to a flat piece of marble, with a diameter of 14 inches depicting a bearded man, was lent by a noble Tuscan family to the Museo Ideale in the Tuscan town of Vinci for a study on the relationship between Michelangelo and Leonardo…
The bas-relief would have been sculpted around 1545, when 70-year-old Michelangelo Buonarroti (1475-1564) had already completed masterpieces such as the David, the Pietà in the Basilica of St. Peter, the Medici chapels in Florence and the Last Judgement in the Sistine Chapel.
