King of the Laurentians, a people of Latium. According to Virgil, Latinus opposed Æneas on his first landing, but subsequently formed an alliance with him, and gave him Lavinia in marriage. Turnus, King of the Rutuli, declared that Lavinia had been betrothed to him, and prepared to support his claim by arms. It was agreed to decide the rival claims by single combat, and Æneas being victor, obtained Lavinia for his wife.
