Masterpiece of the week

Narcissus, c1500, Follower of Giovanni Antonio Boltraffio
Leonardo da Vinci loved young men with long hair in ringlets, wrote his biographer Giorgio Vasari in 1550. He was twice accused of sodomy before a Florentine tribunal. In modern times the father of psychoanalysis Sigmund Freud wrote a biography of Da Vinci that saw him as a gay artist. This painting by one of his imitators shows that a consciously androgynous, subversive subculture surrounded the great artist and inventor. In Greek myth, Narcissus falls in love with his own reflection. This painting makes that an image of aestheticism among the young Leonardesque dudes.
• National Gallery, London.
