Two 15th-century Spanish Jewish scholars, Don Isaac Abravanel and Solomon ibn Verga, gave an explanation now considered folkloric. Both men wrote in two different published works that the first Jews to reach Spain were brought by ship by Phiros who was confederate with the king of Babylon when he laid siege to Jerusalem. Phiros was a Grecian by birth, but who had been given a kingdom in Spain. Phiros became related by marriage to Espan, the nephew of king Heracles, who also ruled over a kingdom in Spain. Heracles later renounced his throne in preference for his native Greece, leaving his kingdom to his nephew, Espan, from whom the country of ''España'' (Spain) took its name. Based upon their testimonies, this eponym would have already been in use in Spain by c. 350 BC.
