Two urns on Jove's high throne have ever stood, the source of evil one, and one of good; from thence the cup of mortal man he fills, blessings to these, to those distributes ills; to most he mingles both.
HomerRage - Goddess, sing the rage of Peleus' son Achilles, murderous, doomed, that cost the Achaeans countless losses, hurling down to the House of Death so many sturdy souls, great fighters' souls, but made their bodies carrion, feasts for the dogs and birds, and the will of Zeus was moving toward its end. Begin, Muse, when the two first broke and clashed, Agamemnon lord of men and brilliant Achilles.
