Here's a longer, more comprehensive article with a translation of the poem in question. It turns out that this poem, a poignant and philosophical look at aging in the presence of youth, was completed by combining it with another fragment of the same poem already extant. The newly discovered papyrus comes from the cartonnage of an Egyptian mummy and was copied in the 3rdc. bce.

The poem is indeed very lovely and moving.
