Note: "Sappho of Lesbos (c. 620-570 BCE) was a lyric poet whose work was so popular in ancient Greece, and beyond, that she was honored in statuary and praised by figures such as Solon and Plato. Very little is known of her life and of the nine volumes of her work which were widely read in antiquity only fragments survive. Contrary to popular opinion on the subject, her works were not destroyed by closed-minded Christians seeking to suppress lesbian love poetry but were lost simply through time and circumstance." Source: Ancient History Encyclopedia.
The popular image of Sappho as the "original lesbian" is relatively modern. According to the Oxford Classical Dictionary (2rd ed. revised), "Her sexual inclinations have occasioned much speculation from antiquity to the present. From Attic comedy onwards she was credited with an implausible selection of male lovers. She is described as a lover of women only in post-Classical times, and in later European tradition was often regarded as heterosexual." The truth is that hardly anything is known about her personal life or her work other than the fact that she was highly regarded during her time. As for her supposed lesbianism, the truth may have been far different:
"Even Sappho’s sexuality, which for modern readers is the most famous thing about her, has been controversial from the start. However exalted her reputation among the ancient literati, in Greek popular culture of the Classical period and afterward Sappho was known primarily as an oversexed predator—of men. This, in fact, was the ancient cliché about 'Lesbians': when we hear the word today we think of love between women, but when the ancient Greeks heard the word they thought of blow jobs. In classical Greek, the verb lesbiazein—'to act like someone from Lesbos'—meant performing fellatio, an activity for which inhabitants of the island were thought to have a particular penchant."
