Ambigatus

king of the Celts in Gaul in the reign of Tarquinius Priscus. He belonged to the Bituriges, the most powerful of the Celtic people. When Ambigatus was advanced in years, he sent out Bellovesus and Sigovesus, the sons of his sister, with large swarms of his people to seek new settlements, in consequence of the great number of the population. Bellovesus and Sigovesus drew lots as to the course they should take; the latter in consequence went to the Hercynian forest and the former into Italy. (Liv. 5.34.)

A king of the Celtae, in the time of Tarquinius Priscus. According to the account given by Livy (v. 34), he sent his two nephews, Sigovesus and Bellovesus, in quest of new settlements, with the view of diminishing the overflowing numbers at home. The two chieftains drew lots respecting their course, and Sigovesus obtianed the route that led towards the Hercynian forest, Bellovesus the road to Italy. What is here stated, however, appears to be a mere legend, owing its origin to the simultaneous emigrations of two hordes of Gallic warriors. See Thierry, Histoire des Gaulois, i. 39.
