Little is known of female homosexuality in antiquity. Sappho , born on the island of Lesbos , was included by later Greeks in the canonical list of nine lyric poets . The adjectives deriving from her name and place of birth ( Sapphic and Lesbian) came to be applied to female homosexuality beginning in the 19th century.   Sappho's poetry centers on passion and love for various personages and both genders. The narrators of many of her poems speak of infatuations and love (sometimes requited, sometimes not) for various females, but descriptions of physical acts between women are few and subject to debate.
