In Greek mythology, Aretus (Ancient Greek Ἄρητος) is a name shared by several figures. The atlas node aretus-nestor is the Pylian prince — son of Nestor and Eurydice (or Anaxibia) — one of the brothers who come forth with their father when Telemachus visits sandy Pylos for the dawn sacrifice to Athena.

I.Son of Nestor at Pylos
Homer names Aretus among Nestor's sons in the Odyssey when the old king leads the sacrifice at dawn; Apollodorus lists him with Thrasymedes, Pisidice, Polycaste, Perseus, Stratichus, Peisistratus, Echephron, and Antilochus. He is a household presence in the Telemachy rather than a battlefield protagonist.
Homonym care: not Aretus son of Bias and Pero; not Priam's Trojan son slain by Automedon; not the Bebrycian who binds Amycus' gauntlets. The atlas id is Nestor's Pylian son alone.
