Bright as that star amid the stars in the night sky
star of the evening, brightest star that rides the heavens,
so fire flared from the sharp point of the spear Achilles
brandished high in his right hand, bent on Hector’s death.

– Homer

The Iliad, Book 22, lines 374-377. Charging Hector and bent on killing him, Achilles’s spear tip glitters like the brightest star in the sky, according to Homer’s extended simile.
