The history of her poems is as speculative as that of her biography. She was known in antiquity as a great poet: Plato called her “the tenth Muse” and her likeness appeared on coins. It is unclear whether she invented or simply refined the meter of her day, but today it is known as “Sapphic” meter. Her poems were first collected into nine volumes around the third century B.C., but her work was lost almost entirely for many years. Merely one twenty-eight-line poem of hers has survived intact, and she was known principally through quotations found in the works of other authors until the nineteenth century. In 1898 scholars unearthed papyri that contained fragments of her poems. In 1914 in Egypt, archeologists discovered papier-mâché coffins made from scraps of paper that contained more verse fragments attributed to Sappho.
