It is sometimes possible to identify regional, tribal, or sub-tribal divinities.Specific to the Remi of northwest Gaul is a distinctive group of stone carvings depicting a triple-faced god with shared facial features and luxuriant beards.
He was worshipped at a number of Treveran sanctuaries, the most splendid of which was at the tribal capital of Trier itself.
Yet he was also exported to other areas: Lenus has altars set up to him in Chedworth in Gloucestershire and Caerwent in Wales.
In all, several hundred names containing a Celtic element are attested in Gaul.
The majority occur only once, which has led some scholars to conclude that the Celtic gods and their cults were local and tribal rather than national.
Not infrequently, their names are coupled with native Celtic theonyms and epithets, such as Mercury Visucius, Lenus Mars, Jupiter Poeninus, or Sulis Minerva.
Unsyncretised theonyms are also widespread, particularly among goddesses such as Sulevia, Sirona, Rosmerta, and Epona.He says that Mercury was the most honoured of all the gods and many images of him were to be found.Mercury was regarded as the inventor of all the arts, the patron of travellers and of merchants, and the most powerful god in matters of commerce and gain.Among the divinities transcending tribal boundaries were the Matres, the sky-god and Epona, the horse-goddess, who was invoked by devotees living as far apart as Britain, Rome and Bulgaria.A distinctive feature of the mother-goddesses was their frequent depiction as a triad in many parts of Britain, in Gaul and on the Rhine, although it is possible to identify strong regional differences within this group.The gods and goddesses, or deities of the Celts are known from a variety of sources, these include written Celtic mythology, ancient places of worship, statues, engravings, cult objects and place or personal names.
