The term Sapphism is derived  from Sappho, an Ancient Greek female lyrical poet born on the Island of Lesbos some time between 630BC and 612BC.

Because she wrote love poetry to both men and women, her name and the island of her birth have become associated with female homosexuality.

Sapphist has been used as a word for a lesbian since the 18th Century, and the term Sapphic passion was used in a London magazine in 1773 to describe sex between women.

Although considered old-fashioned terms for most of the 20th Century, sapphist and sapphic have become popular again amongst the LGBT community.
