Many Celtic divinities were extremely localised, sometimes occurring in just one shrine, perhaps because the spirit concerned was a genius loci, the governing spirit of a particular place. In Gaul, over four hundred different Celtic god-names are recorded, of which at least 300 occur just once. Sequana was confined to her spring shrine near Dijon, Sulis belonged to Bath. The divine couple Ucuetis and Bergusia were worshipped solely at Alesia in Burgundy. The British god Nodens is associated above all with the great sanctuary at Lydney (though he also appears at Cockersand Moss in Cumbria). Two other British deities, Cocidius and Belatucadrus, were both Martial gods and were each worshipped in clearly defined territories in the area of Hadrian's Wall. There are many other gods whose names may betray origins as topographical spirits. Vosegus presided over the mountains of the Vosges, Luxovius over the spa-settlement of Luxeuil and Vasio over the town of Vaison in the Lower Rhône Valley.
