Adelphoe (also written Adelphoi and Adelphi, English: The Brothers) is a play by Roman playwright Terence, adopted partly from plays by Menander and Diphilus. It explores the best form of child-rearing. It was first performed in 160 BC at the funeral games of Aemilius Paulus. It inspired Moliere's The School for Husbands.
Demea, father to Aeschinus and Ctesipho, decides to separate his children and raises Ctesipho while allowing his brother Micio to raise Aeschinus. Demea is a strict authoritarian father, and Micio is permissive and democratic. Ctesipho falls in love and Aeschinus decides to steal the girl away, accepting all blame for the affair. Demea and Micio spar over who did a better job at raising their sons. At the end of the play, Ctesipho marries the music girl and Aeschinus marries Pamphila.
