Sappho's poetry survived longer than that of her contemporaries such as Alcaeus. Only approximately 650 lines of Sappho's poetry still survive, of which just one poem – the "Ode to Aphrodite" – is complete, and more than half of the original lines survive in around ten more fragments. Many of the surviving fragments of Sappho contain only a single word – for example, fragment 169A is simply a word meaning "wedding gifts", and survives as part of a dictionary of rare words. The two major sources of surviving fragments of Sappho are quotations in other ancient works, from a whole poem to as little as a single word, and fragments of papyrus, many of which were rediscovered at Oxyrhynchus in Egypt. Other fragments survive on other materials, including parchment and potsherds. The oldest surviving fragment of Sappho currently known is the Cologne papyrus that contains the Tithonus poem, dating to the third century BC. Until the last quarter of the 19th century, only the ancient quotations of Sappho survived. In 1879, the first new discovery of a fragment of Sappho was made at Fayum. By the end of the 19th century, Grenfell and Hunt had begun to excavate an ancient rubbish dump at Oxyrhynchus, leading to the discoveries of many previously unknown fragments of Sappho. Fragments of Sappho continue to be rediscovered. Most recently, major discoveries in 2004 (the "Tithonus poem" and a new, previously unknown fragment) and 2014 (fragments of nine poems: five already known but with new readings, four, including the "Brothers Poem", not previously known) have been reported in the media around the world. Style Sappho worked within a well-developed tradition of Lesbian poetry, which had evolved its own poetic diction, metres, and conventions. Prior to Sappho and her contemporary Alcaeus, Lesbos was associated with poetry and music through the mythical Orpheus and Arion, and the seventh-century BC poet Terpander. The Lesbian metrical tradition in which Sappho composed her poetry was distinct from that of the rest of Greece as its lines always contained a fixed number of syllables – in contrast to other traditions that allowed for the substitution of two short syllables for one long or vice versa. Sappho was one of the first Greek poets to adopt the "lyric 'I'" – to write poetry adopting the viewpoint of a specific person, in contrast to the earlier epic poets Homer and Hesiod, who present themselves
