Rustic chivalry (Cavalleria rusticana)

Turiddu, a young villager, is the son of Lucia, and the lover of Lola, (who is the wife of Alfio; having married the latter during Turiddu's prolonged absence in military service). Turiddu wins the affections of Santuzza, whom he wrongs; while, in the meantime, he is intimate with Lola. On Easter morning, (the opening of the opera), Alfio is incidentally informed, by Santuzza, of his wife's unfaithful actions. He challenges Turiddu (biting the ear, as was the rustic Sicilian custom). Turiddu, though regretting his past evil course, accepts the challenge and is killed by Alfio.
