Aglaurus, Daughter of Cecrops. Aglaurus or Agraulus was in Greek mythology, an Athenian princess. Aglaurus was the daughter of Cecrops and another Aglaurus, daughter of Actaeus. She had two offspring by two different gods, Alcippe and Ceryx. There were numerous versions of her myth. Taking the earliest first, Euripides Ion, lines 22-23; 484-485, mentions her, but in the Moses Hadas and John Mclean 1960 Bantam Classics translation they have Euripides say respectively: gave Erichthonius to Aglaurus' daughters to keep. and later, speaking ofa haunt of Pan : There the daughters of Aglaurus still tread the measures of their dance, on the green lawns before the shrine of Pallas. According to the Bibliotheca, Hephaestus attempted to rape Athena but was unsuccessful. His semen fell on the ground, impregnating Gaia. Gaia did not want the infant Erichthonius, so she gave the baby to the goddess Athena. Athena gave the baby in a box to three women, Aglaurus and her two sisters Herse and Pandrosus, and warned them to never open it. Aglaurus and Herse opened the box. The sight of the infant caused them both to go insane and they threw themselves off the Acropolis, or, according to Hyginus, into the sea. An alternative version of the same story is that, while Athena was gone bringing a limestone mountain from the Pallene peninsula to use in the Acropolis, the sisters, minus Pandrosus again, opened the box. A crow witnessed the opening and flew away to tell Athena, who fell into a rage and dropped the mountain. Once again, Herse and Aglaurus went insane and threw themselves to their deaths from a cliff. Another legend represents Agraulos in a totally different light. Athens was at one time involved in a long and protracted war, and an oracle declared that it would cease if someone would sacrifice himself for the good of his country. Agraulos came forward and threw herself off the Acropolis. The Athenians, in gratitude for this, built her a temple on the Acropolis, in which it subsequently became customary for the young Athenians, on receiving their first suit of armor, to take an oath that they would always defend their country to the last. According to Ovid, Mercury loved Herse but her jealous sister, whom he calls Aglaurus, stood between them, barring Mercury's entry into the house and refusing to move. Mercury was outraged at her presumption and turned her to stone. One of the Attic demes derived its name from this heroine, and a festival and mysteries were celebrated at Athens in honor of her. According to Porphyry, she was also worshiped in Cyprus, where human sacrifices were offered to her down to a very late time. Mythographers believe Aglaurus to have an origin distinct from that of her sisters, due in part to the fact that she had her own sanctuary near the Acropolis, and unlike her sister Pandrosus, was more associated with young men or soldiers than with infants. She was particularly associated with the festival of Athena called the Plynteria.
