 Part of the Tithonus poem was originally published in 1922 on a fragment of papyrus from Oxyrhynchus . This fragment preserved part of 27 lines of Sappho 's poetry , including the Tithonus poem . The papyrus appears to be part of a copy of Book IV of the Alexandrian edition of Sappho 's poetry , as all of the poems appear to be in the same metre . From the handwriting , the papyrus can be dated to the second century AD . Today the papyrus is part of the collection of the Sackler Library in Oxford University .
