Aplustre (Latin aplustre), or aphlaston (Greek), is a decorative extension of a ship sternpost, usually resembling a rooster tail. Besides rooster-tail forms, aplustres could also resemble the head of a goose or swan; this gave rise to another name, anserculus (Latin for "little goose"). Aplustres, like ship hulls, were brightly painted. Homer, for example, called the ships of Odysseus "red-cheeked" (Homer, Iliad, II,637) and "black" (Homer, Iliad, II,644; 652).
The stern ornament could become a war trophy, symbolising the capture or defeat of an enemy vessel. Juvenal (Satires X.134–136) includes ship ornaments among the signs of military glory. This does not make the aplustre literally the standard of an infantry century: the comparison concerns the symbolic significance of part of the ship.
