Elizabeth Abbott, in her "History of Celibacy", contends that, although Leonardo was probably homosexual, the trauma of the sodomy case converted him to celibacy for the rest of his life. A similar view of a homosexually inclined but chaste Leonardo appears in a famous 1910 paper by Sigmund Freud, "Leonardo da Vinci, A Memory of His Childhood", which analysed a memory Leonardo described of having been attacked as a baby by a bird of prey that opened his mouth and "stuck me with the tail inside my lips again and again". Freud claimed the symbolism was clearly phallic, but argued that Leonardo's homosexuality was latent, and that he did not act on his desires. However, Freud's premise was based on an erroneous translation of the bird as a vulture, leading him in the direction of Egyptian mythology, when it was actually a kite in Leonardo's story.
