is a 1977 French romantic and erotic drama film, which was directed by photographer David Hamilton (1933-2016) with a music score by Francis Lai. It starred Patti D'Arbanville and Mona Kristensen as the title character Bilitis and Melissa, respectively.
The film was loosely based on a poem cycle by Pierre Louÿs entitled The Songs of Bilitis set in ancient Greece, although the film is set in modern Europe. The poems were meant to be autobiographical poems by the title character.
A teenage schoolgirl spends the summer with a couple whose marriage is on the rocks, and develops a lesbian crush on the wife. Meanwhile, she pursues a local teenage boy and tries to find a "suitable male lover" for the wife.
Although Bilitis can be best described as a coming of age film the title character, Bilitis, ends up returning to school at the end of the film, realizing that she is not yet ready for adulthood.
