Ghirlandaio - Tornabuoni Chapel - a Humanist philosopher

(detalj) This portrait is one of four philosophers of the Medici Platonic Academy. It has been associated with Demetrios Chalkokondyles, and was engraved and published as such around 1900. However, it closely resembles other portraits, including one in Benozzo Gozzoli's Procession of the Magi, that are identified as Gentile Becchi. If this is NOT Becchi, where is Becchi in the painting? He was a constant at the Medici court and was politically of greater significance than Chalkondyles. Those who believe it to represent Becchi include E. H. and E. W. Blashfield in their annotations to Vasari's Lives of Seventy of the Most Eminent Painters, Sculptors and Architects, VOL. II (1896) Charles Scribener and Son. [1] and Hugh Ross-Williamson, Lorenzo the Magnificent, Michael Joseph, (p. 179) ISBN 0718112040
