Ptolemy Hephaestion, New History Bk7 (as summarized in Photius, Myriobiblon 190)
Those who dive from the top of the rock [of Leukade on the island of Leukos in Western Greece] were, it is said, freed from their love and for this reason: after the death of Adonis, Aphrodite, it is said, wandered around searching for this. She found it in Argos, a town of Kypros, in the sanctuary of Apollon Erithios and ‘ l’emporta’ after having told Apollon in confidence the secret of her love for Adonis. And Apollon brought her to the rock of Leukade and ordered her to throw herself from the top of the rock; she did so and was freed from her love. When she sought the reason of this, Apollon told her, it is said, in his capacity as a soothsayer, he knew that Zeus, always enamoured of Hera, had sat on this rock and been delivered from his love.
