In Greek mythology, Aegle (Ancient Greek Αἴγλη, "brightness / evening light") is one of the Hesperides who tend Hera's golden apples beside Ladon. Apollodorus names her with Erythia, Hesperia, and Arethusa; Apollonius has shining Aegle lament the slain dragon and speak from a willow trunk.

I.Among the apple-guardians
Apollodorus lists four sisters at Ladon's watch: Aegle, Erythia, Hesperia, and Arethusa. Apollonius prefers three — Aigle, Erytheis, and Hespere — and after Heracles has already killed the serpent the Argonauts hear Aegle's lament; changed into trees, she becomes a willow's sacred trunk and directs the thirsty heroes to a spring.
Hyginus places Aegle among Hesperides born of Night. Parentage of the whole brood (Nyx, Atlas, Phorcys, etc.) stays on the collective hesperides node.
II.Homonym care
The atlas id aegle-hesperid with kinds hesperid is this evening nymph alone. Distinct from Aegle daughter of Helios in the Phaethon tale, from the Hyacinthid maiden at Athens, and from other Aegle namesakes.
