Maria Sibylla Merian

Cumaean Sibyl
Although she was a mortal, the Sibyl lived about a thousand years. She attained this longevity when Apollo offered to grant her a wish in exchange for her virginity; she took a handful of sand and asked to live for as many years as the grains of sand she held. Later, after she refused the god's love, he allowed her body to wither away because she failed to ask for eternal youth. Her body grew smaller with age and eventually was kept in a jar ("ampulla"). Eventually only her voice was left ("Metamorphoses" 14; compare the myth of Tithonus).
