A powerful Celtic people in Gallia Belgica, inhabiting the country since called Franche
Comté and Burgundy. In the later division of the provinces of the Empire the
country of the Sequani formed a special province under the name of Maxima
Sequanorum. They derived their name from the river Sequana, which had its source in the
northwestern frontiers of their territory. Their chief town was Vesontio (Besançon)
i. 1, 3, 10-12; Lucan, i. 425).
