Lampetia

In Homeric and later traditions Lampetia is presented as a daughter of Helios associated with his household and cattle on Thrinacia. Some accounts name Neaera as her mother; in alternate genealogies she is grouped among the Heliades (daughters of Helios and Clymene) and in a fragmentary, later tradition (Hermippus' Trimeters) she is said to have borne children by Asclepius. Sources therefore vary; the most consistent element is her role as Helios's attendant and keeper of his herd.

Ancient sources give minimal physical description. Her name (Λαμπετίη, 'shining') evokes light and her filial association with the Sun. She is described in summary accounts as a herdswoman who is sometimes said to carry an orichalcum staff; beyond this functional motif—staff and herding role—no consistent bodily portrait (clothing, age, facial features) is supplied in the cited materials.

Lampetia's demonstrable powers in the sources are custodial and social rather than magical: she watches and tends Helios's sacred cattle and sheep and, when those animals are violated in the Odyssey, she and her sister run to inform their father, prompting Helios to demand divine punishment. Homer characterizes the herd as not aging or breeding in his account; Lampetia's active agency is to guard and to report infringements. Some later or alternative genealogical fragments attribute other familial roles (e.g., motherhood to Asclepius's children) but these are disputed and do not add documented supernatural powers.
