It is not Kadmus, but the brothers Amphiôn and Zethus, who are given to us in the Odyssey as the first founders of Thêbes and the first builders of its celebrated walls. They are the sons of Zeus by Antiopê, daughter of Asôpus. The scholiasts who desire to reconcile this tale with the more current account of the foundation of Thêbes by Kadmus, tell us that after the death of Amphiôn and Zethus, Eurymachus, the warlike king of the Phlegyæ, invaded and ruined the newly-settled town, so that Kadmus on arriving was obliged to re-found it.[618] But Apollodôrus, and seemingly the older logographers before him, placed Kadmus at the top, and inserted the two brothers at a lower point in the series. According to them, Bêlus and Agenôr were the sons of Epaphus, son of the Argeian Iô, by Libya. Agenôr went to Phœnicia and there became king: he had for his offspring Kadmus, Phœnix, Kilix, and a daughter Eurôpa; though in the Iliad Eurôpa is called daughter of Phœnix.[619] Zeus fell in love with Eurôpa, and assuming the shape of a bull, carried her across the sea upon his back from Egypt to Krête, where she bore to him Minôs, Rhadamanthus and Sarpêdôn. Two out of the three sons sent out by Agenôr in search of their lost sister, wearied out by a long-protracted as well as fruitless voyage, abandoned the idea of returning home: Kilix settled in Kilikia, and Kadmus in Thrace.[620] Thasus, the brother or nephew of Kadmus, who had accompanied them in the voyage, settled and gave name to the island of Phasus.

[620] Apollodôr. ii. 1, 3; iii. 1, 8. In the Hesiodic poems (ap. Schol. Apoll. Rhod. ii. 178), Phœnix was recognized as son of Agenôr. Pherekydês also described both Phœnix and Kadmus as sons of Agenôr (Pherekyd. Fragm. 40, Didot). Compare Servius ad. Virgil. Æneid. 1. 338. Pherekydês expressly mentioned Kilix (Apollod. _ib._). Besides the Εὐρώπεια of Stesichorus (see Stesichor. Fragm. xv. p. 73, ed. Kleine), there were several other ancient poems on the adventures of Europa; one in particular by Eumêlus (Schol. ad Iliad. vi. 138), which however can hardly be the same as the τὰ ἔπη τὰ εἰς Εὐρώπην alluded to by Pausanias (ix. 5, 4). See Wüllner de Cyclo Epico, p. 57 (Münster 1825).
