In Greek mythology, Agelaus or Agelaos (Ancient Greek Ἀγέλαος) is a name of many figures. The atlas node agelaus-lydian is the son of Heracles and Omphale, queen of Lydia, from whom Apollodorus derives the ancestry of Croesus — the genealogical bridge between the hero's Lydian servitude and later Lydian kingship. Other sources call this son Lamus instead.

I.Son of Heracles and Omphale
When the Delphic oracle sold Heracles into bondage, Omphale bought him and he served at her court. Apollodorus counts among his children by Omphale a son Agelaus, ancestor of Croesus' house — though Croesus himself lies outside the seven atlas lenses.
Homonym care: the atlas keeps many other Agelaus figures (Paris' herdsman, Calydonian prince, Penelope's Sameian suitor, Temenid fratricide, Trojan casualties) under distinct ids. This node is the Lydian son alone.
