Illyrius

Illyrius (Ancient Greek: Ἰλλυριός, Illyriós) is the son of Cadmus and Harmonia, who eventually ruled Illyria and became the eponymous ancestor of the Illyrians.

[6] In the Roman period, Illyricum, a term which signified a broader region than Illyria, was used for the area between the Adriatic and Danube.

[4] [7] According to the Bibliotheca, Illyrius was the youngest son of Cadmus and Harmonia who eventually ruled Illyria and became the eponymous ancestor of the whole Illyrian people.

[10] According to the Illyrian Wars of Appian, Illyrius was the son of the Cyclops Polyphemus and his wife Galatea with siblings Celtus and Galas.

[11] This particular genealogy was most likely composed by the ancient Greek founders of Epidamnus (Corinthians and Corcyrans) and preserved in Appian's work.
