Who was the most famous female poet in ancient Greece?

Sappho was a Greek lyric poet greatly admired in all ages for the beauty of her writing style. She ranks with Archilochus and Alcaeus, among Greek poets, for her ability to impress readers with a lively sense of her personality. Her language contains elements from Aeolic vernacular speech and Aeolic poetic tradition, with traces of epic vocabulary familiar to readers of Homer. Her phrasing is concise, direct, and picturesque. She can stand aloof and judge critically her own ecstasies and grief, and her emotions lose nothing of their force by being recollected in tranquillity.
