Out of these deities, some, it is true, in the process of evolution, gained a wider field of worshippers, while others, like Lugus, may even have been at one time more widely worshipped than they came to be in later times.
Occasionally a name like Lugus (Irish _Lug_), Segomo (Irish, in the genitive, _Segamonas_), Camulos, whence Camulodunum (Colchester), Belenos (Welsh _Belyn_), Maponos (Welsh _Mabon_), Litavis (Welsh _Llydaw_), by its existence in Britain as well as in Gaul, suggests that it was either one of the ancient deities of the Aryan Celts, or one whose worship came to extend over a larger area than its fellows.

Apart from a few exceptional considerations of this kind, however, the local character of the deities is most marked.
A very considerable number are the deities of springs and rivers.

In Noricum, for example, we have Adsalluta, a goddess associated with Savus (the river Save).

In Britain 'the goddess' Deva (the Dee), and Belisama (either the Ribble or the Mersey), a name meaning 'the most warlike goddess,' are of this type.

We have again Axona the goddess of the river Aisne, Sequana, the goddess of the Seine, Ritona of the river Rieu, numerous nymphs and many other deities of fountains.
