 The papyrus is part of an anthology of poetry , with poems on similar themes grouped together . Along with the Tithonus poem , two others are preserved on the papyrus published by Gronewald and Daniel : one in the same metre , one written in a different hand and in a different metre . The metre of this last poem has characteristics which do not appear in any known metre used by the Lesbian poets . It also contains word forms which appear not to be in the Aeolic dialect used by Sappho , and refers to the myth of Orpheus in a form not known to have existed in Sappho 's time . For these reasons , the poem cannot be by Sappho .
