Cycnus (son of Ares)

For other uses, see Cycnus.

In Greek mythology, Cycnus (Ancient Greek: Κύκνος means "swan") or Cygnus was a bloodthirsty and cruel man who dwelt either in Pagasae, Thessaly or by the river Echedorus in Macedonia.

Zeus parts Athena and Ares, while Kyknos flees in a chariot (right) as Heracles arrives (left), on an Attic black-figured volute-krater, c. 540–510 BCE signed by Nikosthenes (British Museum).

Family

Cycnus was the son of Ares by Pelopia or Pyrene. He married Themistonoe, daughter of King Ceyx of Trachis.

Mythology

Cycnus killed all of his guests until he was slain by Heracles. According to Pausanias, one of the men murdered by him was Lycus of Thrace.

Pseudo-Apollodorus wrote of Cycnus the Thessalian, the son of Pelopia, and Cycnus the Macedonian, the son of Pyrene, as two distinct encounters of Heracles, mentioning them separately. The Thessalian Cycnus, he relates, challenged Heracles to single combat and was killed by him; the same is recounted by Diodorus. The Macedonian Cycnus, according to the Bibliotheca, also challenged Heracles to single combat; Ares attempted to avenge his son's death, but a thunderbolt was hurled by Zeus between the combatants, causing them to part.

Heracles fights Cycnus, from the Treasury of the Athenians at Delphi.

In the Shield of Heracles, Heracles and his nephew, Iolaus, are traveling through Thessaly on their way to Trachis when they are encountered by Cycnus and Ares, each pair riding a chariot; it is mentioned that Heracles was directing to the court of King Ceyx.

Apollo, whose Pagasaean sanctuary was next to the place where the characters meet, is said to have stirred Heracles up against Cycnus.

Heracles accepts Cycnus' challenge and as he puts on his armor to prepare for battle, Athena appears before him, and tells Heracles that, should he kill Cycnus in the ensuing battle, he is to not take his armor as spoils, but instead focus his attention on Ares, as he will surely attack Heracles to avenge Cycnus' death.

Heracles and Cycnus then clash in single combat; Cycnus hurls his spear at Heracles' shield, but fails to penetrate it, after which Heracles drives his spear through Cycnus' neck, killing him. Ares is enraged by his son's death and moves to kill Heracles when Athena appears before him, urging him to check his anger and cease fighting. Ares refuses to listen, however, and again charges at Heracles, hurling his spear at his shield; Athena, however, turns his spear aside.

Ares then draws his sword and leaps at Heracles, who, seeing an opening, thrusts his spear into Ares' thigh, causing the god to fall to the ground; Ares' twin sons, Phobos and Deimos, appear to rescue him and take him back to Mount Olympus.

Heracles then strips Cycnus of his armor, after which he and Iolaus continue on their journey to Trachis; Cycnus was buried by his father-in-law Сeyx and people of the neighboring cities, but Apollo, still angry over Cycnus' actions, has the river Anaurus flood the area and wash Cycnus' tomb away.

According to Euripides, Heracles shot Cycnus with his arrows, and this took place in Amphanae near the river Anaurus.

Eustathius of Thessalonica informs that Ares changed Cycnus into a swan rather than let him die by the hand of Heracles.
