In order to produce a profile of the Celtic deities of Hispania based on the study of votive altars, a rigorous critique of the inscriptions must be implemented, eliminating those that are not reliable due to their poor condition or because they were lost before systematic analysis could be carried out on them. First all the areas in which certain groups of gods were worshipped are located in order to establish a scheme of the way their pantheon functioned. Next groups of theonyms are analyzed to detect possible relationships between them and the areas occupied by the different Hispanic populi. Finally, the main characteristics of the different deities are established.
