of a horse, although not without a certain amount of grumbling. Tyndareus chose Menelaus. Menelaus was a political choice on her father's part. He had wealth and power. He had humbly not petitioned for her himself, but instead sent his brother Agamemnon on his behalf. He had promised Aphrodite a hecatomb, a sacrifice of 100 oxen, if he won Helen, but forgot about it and earned her wrath. Menelaus inherited Tyndareus' throne of Sparta with Helen as his queen when her brothers, Castor and Pollux, became gods, and when Agamemnon married Helen's sister Clytemnestra and took back the throne of Mycenae. Paris, under the guise of a supposed diplomatic mission, went to Sparta to get Helen and bring her back to Troy. Before Helen could look up to see him enter the palace, she was shot with an arrow from Eros, otherwise known as Cupid, and fell in love with Paris when she saw him, as promised by Aphrodite. Menelaus had left for Crete to bury his uncle, Crateus. According to one account, Hera, still jealous over the judgement of Paris, sent a storm. The storm caused the lovers to land in Egypt, where the gods replaced Helen with a likeness of her made of clouds, Nephele. The myth of Helen being switched is attributed to the 6th century BC Sicilian poet Stesichorus, while for Homer the Helen in Troy was one and the same. The ship then landed in Sidon. Paris, fearful of getting caught, spent some time there and then sailed to Troy. Paris' abduction of Helen had several precedents. Io was taken from Mycenae, Europa was taken from Phoenicia, Jason took Medea from Colchis, and the Trojan princess Hesione had been taken by Heracles, who gave her to Telamon of Salamis. According to Herodotus, Paris was emboldened by these examples to steal himself a wife from Greece, and expected no retribution, since there had been none in the other cases. Gathering of Achaean forces and the first expedition According to Homer, Menelaus and his ally, Odysseus, traveled to Troy, where they unsuccessfully sought to recover Helen by diplomatic means. Menelaus then asked Agamemnon to uphold his oath, which, as one of Helen's suitors, was to defend her marriage regardless of which suitor had been chosen. Agamemnon agreed and sent emissaries to all the Achaean kings and princes to call them to observe their oaths and retrieve Helen.
