The Mother-in-Law (Latin: Hecyra) is a Latin comedy by Terence. It's first performance in 165 BC was a failure, as the audience halting the performance in favour of a boxing match.
The plot centres on the unseen character of Philumela, who flees the home of her husband's parents to conceal the fact that she is pregnant, having been debauched by an unknown assailant. A resolution emerges through a ring stolen during the encounter.
