Caucas or Kavkasos was the supposed ancestor of Vainakh peoples according to The Georgian Chronicles. His story is narrated in the compilation of the medieval Georgian chronicles, Kartlis Tskhovreba, taken down from oral tradition by Leonti Mroveli in the 11th century. The legend has it that he was a son of Targamos and, thus, brother of Hayk, Movakos, Lekos, Heros, Kartlos, and Egros.
