Cycnus of Troy- Greek DemigodDemigod"King of Colonae"

Lineage and Kingship

Cycnus was a son of Poseidon, granted invulnerability by his divine father so that no weapon of bronze or iron could pierce his flesh. He ruled as king of Colonae, a city on the Troad coast near the Hellespont. By his first wife, he fathered two children: Tenes, who would become the eponymous ruler of Tenedos, and Hemithea. After his first wife's death, Cycnus married Philonome, who conceived a passion for her stepson Tenes. When Tenes rejected her, Philonome accused him before Cycnus of assault. Believing his wife, Cycnus sealed Tenes and Hemithea in a chest and cast them into the sea. The chest washed ashore on the island of Leucophrys, which Tenes renamed Tenedos and ruled as king. Cycnus later discovered Philonome's deception and had her buried alive, then sailed to Tenedos seeking reconciliation. Apollodorus says Tenes refused him, cutting the mooring ropes of his father's ship with an axe.

Death at the Trojan Shore

When the Greek fleet arrived at the Troad, Cycnus marshaled his forces on the beach to repel the landing. He strode into the surf-line battle untouched by every spear and arrow that struck him. Achilles, confronting this immovable defender, hurled his javelin and watched it glance harmlessly off Cycnus's chest. Realizing no blade could harm the son of Poseidon, Achilles drove him to the ground with the boss of his shield, knelt upon his chest, and strangled him with the leather straps of his own helmet. When the Greeks came to strip the body, they found only a white swan rising from the fallen armor. Poseidon had transformed his son at the moment of death.
