quote: ''
summary: The passage gives explanatory interpretations of the Centaurs, their Thessalian
horsemanship, alleged cloud-birth and descent from Ixion, their conflict with
Pirithoüs and the Lapithæ, and later traditions about their retreat. It also summarizes
episodes in which Periclymenus transforms into an eagle and is killed by Hercules,
and Apollo in disguise directs Paris's arrow against Achilles at the heel after
Neptune seeks vengeance for Cygnus.

on horsemanship.

of the hybrid form.

basis: The passage says poets made the Centaurs sons of Ixion and of a cloud substituted

evidence_refs:

cautions: The miraculous-child classification is tentative because the passage treats
the cloud birth as an explained fable rather than narrating births.

cautions: The passage says 'attempt' and does not detail abduction or successful
seizure.
- id: motif:4
label: wild mountain people against town-builders

horse-riding, the other town-founding and more civilized, with the Centaurs driven
back toward mountains.

the passage frames the action as vengeance and disguise, not as formal judgment.
