Iarbas
In Roman mythology, Iarbas or Hiarbas was the son of Jupiter Hammon (Hammon was a North African god associated by the Romans with Jupiter, and known for his oracle) and a Garamantian nymph. He became the king of Gaetulia. According to Virgil's Aeneid, he fell in love with the Carthaginian queen Dido, who rejected his advances in favour of Aeneas. Variations of the story were narrated by Ovid, Macrobius, and Pompeius Trogus; in Justin's epitome of Pompeius he is king of the Maxitani.
There was also a historical king of Numidia called Hiarbas who reigned from 84-82 BC.
