One of the four Hesperides whom Apollodorus names beside Ladon at the golden-apple tree — in his text Erythia, the radiant 'Red One' of sunset — not to be confused with Erytheia the island home of Geryon's cattle in the western labour.1
Apollodorus, recounting Heracles' eleventh labour, lists the nymphs who guarded the apples with the hundred-headed dragon offspring of Typhon and Echidna: Aegle, Erythia, Hesperia, and Arethusa. The Perseus translation prints 'Erythia'; the standard Greek form Erytheia names the evening nymph of the western garden, distinct from the far western cattle-land of Geryon.2
Apollonius' Argonautica preserves a shorter roll of three names at the same garden — Hespere, Erytheis, and Aegle — and shows Erytheis changed into an elm when the sisters took tree-form after Ladon's death. The atlas treats Erytheis and Apollodorus' Erythia as the same evening nymph under the id `erytheia-hesperid`, while the collective `hesperides` node still carries Hesiod's fatherless brood of Night.3
