According to legend, Psyche was a beautiful young girl—so lovely, in fact, that Venus herself was jealous of the girl’s comeliness. Thus, she sent her son Eros (Cupid to the Romans), god of love, to sabotage the girl and make her fall in love with a hideous creature. However, the fumbling young god was himself taken with the girl’s beauty and stuck himself with his own arrow, thereby causing his scheming mother’s plan to backfire. The young lovers have been the subject of artists for nearly as long as the myth itself has existed. Some artists portrayed the two as adolescents and others have depicted them as children. Among the oddest of these portrayals are the ones which show Psyche as a young woman while keeping Eros in the form of a small boy. Among the oldest of artworks featuring Eros and Psyche the two seem to be of ambiguous age.
