In an earlier post – When Leonardo was ‘murdered’ by Moses (and Botticelli) in the Sistine Chapel – I wrote:
“Another narrative is that Leonardo was perhaps at odds with himself, battling with his sexuality and experiencing his nature to be in conflict with the law that threatened not only his existence but also his way of life, hence the reason why Botticelli depicted Leonardo as both of the Hebrew men.”
After further research I can now add more to this conflict narrative between the two Hebrew men. They also represent two artists, one being Leonardo da Vinci falling under the sword of Moses and the Law (still to be received); the other, portrayed under the protection of Florentina, is Domenico Ghirlandaio, a contemporary of Leonardo and one of the Florentine group of artists responsible for frescoing the walls of the Sistine Chapel.
More details on this at a later date.
