Plutarch, Parallela minora
Frank Cole Babbitt, Ed.

Through the wrath of Aphroditê, Smyrna, the daughter of Cinyras, fell in love with her father, and revealed to her nurse the all-compelling force of her love. The nurse led on her master by a trick ; for she declared that a neighbouring maiden was in love with him and was too modest to approach him openly ; and Cinyras consorted with her. But on one occasion, wishing to learn the identity of his mistress, he called for a light ; but when he saw her, sword in hand he pursued this most wanton woman. But by the foresight of Aphroditê she was changed into the tree that bears her name.¹ So Theodorus in his Metamorphoses.

Through the wrath of Venus, Valeria Tusculanaria [p. 291] fell in love with her father Valerius, and imparted her secret to her nurse. The nurse deceived her master by a trick, saying that there was someone who was too modest to consort with him openly, but that she was a maiden of the neighbourhood. The father, sodden with wine, kept calling for a light; but the nurse was quick enough to wake the daughter, who went to the country, since she was with child. Once on a time she threw herself down from a cliff, but the child still lived. Returning home, she found her pregnancy inescapable, and in due time gave birth to Aegipan, called in the Roman tongue Silvanus. But Valerius, in a fit of despair, hurled himself down from the same cliff. So Aristeides the Milesian in the third book of his Italian History.
