Ovid.

Herois 5, Oenone to Paris. In this letter the water-nymph Oenone directs her bitterness and desperation at Paris, who abandoned her in favor of the Greek Helen. She recounts the earlier, simpler days when she and he used to live in the country, completely devoted to one another. Her tone is at times deeply moving and intimate, at others utterly desperate to have her love requited.

Herois 6, Hypsipyle to Jason. Hypsipyle, the Queen of Lemnos (the island with no men that was the first stop of the Argonauts), writes to Jason after he has obtained the Golden Fleece and returned home--without returning to Hypsipyle and having picked up the Princess Medea as his new love.
