Narrative
When Helen reached marriageable age, suitors from all Greece gathered at the house of Tyndareus (or of her brothers) in Sparta—men of rank including Odysseus, Ajax, Diomedes, and many others later famous at Troy. Tyndareus feared that choosing one would make enemies of the rest. Odysseus proposed a solution (in exchange for Tyndareus’s help winning Penelope): all the suitors should swear to defend whoever became Helen’s husband if any man wrongfully took her. They swore over the severed pieces of a horse (or other solemn rite). Tyndareus then gave Helen to Menelaus; Agamemnon already had Clytemnestra.
Years later, when Paris took Helen, Menelaus remembered the oath. With Agamemnon he traveled through Greece calling the former suitors and their allies to arms. The *Cypria* and Apollodorus show the muster assembling toward Aulis in Boeotia: kings and contingents answer because of the sworn bond, kinship, and Agamemnon’s overlordship. Those who hung back were fetched by force or cunning (next entry: Odysseus). The oath is the legal-mythic engine of the pan-Achaean expedition: without it, Helen’s seizure is a Spartan private wrong; with it, it becomes a collective war.
