AGLAWROS. Aglauros was the daughter of Cecrops, the Athenian king. Mercury fell in love with her sister Herse and asked Aglauros to help him. Aglauros demanded gold, and Pallas Athena, patroness of Athens, was displeased with her cupidity, sending Envy to infect Aglauros's heart. Then Aglauros forbade Mercury to visit Herse. The god touched her with his magic wand, and Aglauros slowly turned to stone (Met II.722-832; OM II.3777-3898, 4044-4076).
Troilus invokes Mercury's help for the love of Hierse, because of which Pallas was angry with Aglawros, Tr III.729-735. [Hierse: Mercurie: Pallas]
The spelling Aglawros suggests that the form is derived through pronunciation.
