quote: ''
summary: Acheloüs recounts how, after taking serpent form, he was mocked and overpowered
by the Tirynthian, who cited his earlier victories over serpents and the Lernaean
monster. Acheloüs then changed into a bull, but his opponent threw him down, broke
off one horn, and the Naiads consecrated that horn as an abundance vessel associated
with Plenty. At dawn the young men depart, while Acheloüs hides his mutilated
horn and rustic features in the waves, covering the injury with willow branches
or reeds.

consecrated by Naiads, enriches Plenty, and carries autumn produce.

evidence_refs:
- ev:11
confidence: medium
cautions: The concealment is literal in this passage; broader symbolic meaning would
require external evidence.
comparison_claims:
- id: claim:1
claim: The passage explicitly compares Acheloüs' assumed serpent form with earlier
serpent opponents of the Tirynthian, especially the Lernaean monster, while also
stressing that Acheloüs is only one serpent and unlike the multiplying Hydra.
claim_level: same_function
target: Heraclean serpent-combat pattern, including cradle serpents and the Lernaean
Hydra
evidence_refs:
- ev:2
- ev:3
- ev:6
- ev:7
counter_evidence_refs:
- ev:2
confidence: medium
limitations: The comparison is made inside the speech as a taunt; it supports shared
function as serpent opponents of Hercules, not identity or full equivalence between
Acheloüs and the Hydra.
