Sappho was an ancient Greek lyric poet from the island of Lesbos. She wrote around 10,000 lines of poetry, only a small fraction of which survives. Only one poem is known to be complete; in some cases as little as a single word survives. Modern editions of Sappho's poetry are the product of centuries of scholarship, first compiling quotations from surviving ancient works, and from the late 19th century rediscovering her works preserved on fragments of ancient papyri and parchment. Along with the poems which can be attributed with confidence to Sappho, a small number of surviving fragments in her Aeolic dialect may be by either her or her contemporary Alcaeus. Modern editions of Sappho also collect ancient "testimonia" which discuss Sappho's life and works.
