Ovid was lax in his geography, not least over Paeonia (in fact roughly coextensive with the present F.Y.R.O.M.).
Lysimachus conducted Ariston, son of Autoleon, to his father's kingdom in Paeonia; under pretence that the royal youth might be acknowledged by his subjects, and treated with due respect. But as soon as he had bathed in the royal baths in the river Arisbus, and they had set before him an elegant banquet, according to the custom of his country, Lysimachus ordered his guards to arm. Ariston instantly mounted his horse and escaped to the land of the Dardani; and Lysimachus was left in possession of Paeonia.
