The mother of the husband of Erato was set among the stars as what constellation?
Erato (dryad) In Greek mythology, Erato ( ; Ancient Greek: Ἐρατώ "desired" or "lovely") was a dryad. She was the priestess and prophetess of the god Pan, verses were attributed to her at an ancient oracle of the god, located at Megalopolis near Acacesium. Erato was married to Arcas, the son of Zeus and Callisto, and bore him three sons, Azan, Apheidas, and Elatus.
Catasterismi Catasterismi (Greek Καταστερισμοί "Katasterismoi", "placings among the stars") is an Alexandrian prose retelling of the mythic origins of stars and constellations, as they were interpreted in Hellenistic culture. The work survives in an epitome assembled at the end of the 1st century CE, based on a lost original with some possible relation to the work of Eratosthenes of Cyrene; thus the author is alluded to as Pseudo-Eratosthenes. The pseudepigraphic attribution to Eratosthenes presumably was meant to bolster the work's credibility, but while the "Catasterismi" describes constellations, it is more concerned with the mythological narrative attached to each than with the mathematical tradition of astronomy. Although there is no absolute distinction between astronomy and astrology in antiquity, intellectual circles in Alexandria during the 1st BCE began to distinguish between astrology for making predictions and astronomical observation for scientific conjecture.
