Acropolis - Cave of Aglauros

The most easterly of the sacred caves at Acropolis, lying below the House of the Arrhephoroi, is the Cave of Aglauros, in which sacred festivals were celebrated with music and dancing. Here, too, the ephebes swore their oath. The cave is named after Aglauros, one of the three daughters of Kekrops. She and her sister Herse opened a casket which had been entrusted to them by Athena, although they had been forbidden to tamper with it: whereupon they lost their reason and sprang to their deaths from the summit of the Acropolis. The third of the sisters, Pandrosos, escaped this fate and has a sanctuary dedicated to her on the Acropolis.
