Norax was the son of Hermes and Erythea. He led a colony to Sardinia and there founded Nora, the island's oldest city. As it stands, his name has no obvious meaning at all.

Robert Graves suggests it may be a miswriting of 'Norops', meaning 'sun face', literally 'flashing', this being some kind of complimentary or belligerent name ('face too bright to look at').
