The Achilleid is the third and unfinished work by the Roman poet Publius Papinius Statius. In its introduction, it promises to present the life of the hero Achilles from his youth as a pupil under the centaur Chiron to his death at Troy. The author died however before writing most of the poem, leaving only one and a half books completed. The part that remains though holds interest for being unusual, bringing an account of the hero's early life and an episode in which his mother, Thetis, disguised him as a girl on the island of Scyros before he joined the Greek expedition against Troy.
