There were altars all around and the priestess with hair streaming called with a voice of thunder upon three hundred gods, Erebus, Chaos, triple Hecate, and virgin Diana of the three faces. She had also sprinkled water to represent the spring of Lake Avernus. She also sought out potent herbs with a milk of black poison in their rich stems and harvested them by moonlight with a bronze sickle. She found, too, a love charm, torn from the forehead of a new-born foal before the mare could bite it off. Dido herself took meal in her hands and worshipped, standing by the altars with one foot freed from all fastenings and her dress unbound, calling before she died to gods and stars to be witnesses to her fate and praying to whatever just and mindful power there is that watches over lovers who have been betrayed.
Virgil, Aeneid, 4.509-522.
