CREON became king of Thebes during the war of the Seven Against Thebes, after Etiocles and Polynices, sons of Oedipus, killed each other during the battle. He refused burial for the bodies of the enemy, but Theseus intervened with an army, killed Creon, and allowed the dead warriors to be buried (Thebaid XII.773-781; Roman de Thèbes, 10003-10172).

Theseus rides out to fight Creon, his pennant embroidered with the figure of the Minotaur borne before him, KnT 979-980; he expects to slay Creon as he had killed the Minotaur. He fights and slays Creon, KnT 986-988, 1002. The incident also appears in Tes II.10-66. When Creon of Thebes sees how the royal families of Thebes have been decimated by the wars, he invites the nobility of the region to dwell in the city, Anel 64-70. Jason chooses the daughter of King Creon as his third wife, LGW 1660-1661. [Jason: Theseus]

Creon appears five times in medial positions, KnT 938, 961, 963, 1002; Anel 64; and once in final rhyming position, LGW 1661.
