When was the first recorded divorce in Roman history?
According to Cato the Elder, clan custom required a husband to divorce an adulterous wife. The consequences were much worse if the infidelity was witnessed by the husband: "If you find your wife in the act of adultery, the law permits you to kill her without trial. If by chance she surprises you in the same condition, she must not touch you even with the tips of her fingers; the law forbids her." Cato quoted by Aulus Gellius, Noctes Atticae, 10.23.2-5. (Attic Nights).
