Of the gods identified with Hercules, the most interesting name is Ogmios (the god of the furrow) given by Lucian, but not found on any inscription.

The following gods too, among others, are identified with Jupiter: Aramo (the gentle), Ambisagrus (the persistent), Bussumarus (the large-lipped), Taranucus (the thunderer), Uxellimus (the highest).

It would seem from this that in historic times at any rate Jupiter did not play a large part in Celtic religious ideas.
There remains another striking feature of Celtic religion which has not yet been mentioned, namely the identification of several deities with Apollo.

These deities are essentially the presiding deities of certain healing-springs and health-resorts, and the growth of their worship into popularity is a further striking index to the development of religion side by side with certain aspects of civilisation.

One of the names of a Celtic Apollo is Borvo (whence Bourbon), the deity of certain hot springs.
