summary: The passage explains the mythic combat between Hercules and the river Acheloüs
as an allegory for controlling destructive floods and unifying river channels.
It then summarizes and begins the episode in which Hercules returns with Deïanira,
entrusts her to the centaur Nessus at the swollen Evenus, and the later chain
of Nessus’ attempted abduction, poisoned tunic, Hercules’ death by fire, and translation
to the gods.

warfare caused by flooding and boundary disruption.

combat rather than as the poetic narrative itself.

basis: The river god Acheloüs transforms into serpent and bull forms during combat
with Hercules.

and overflowing force.

the river.

not a separate narrated serpent episode in the excerpt.

variant accounts include an exchange involving Amalthea’s horn, the Nymphs, and
Acheloüs.

a violent taking of a horn with variant exchange traditions.
