The Celts were polytheists, believing in multiple gods and goddesses. Regional deities were known throughout the Celtic regions, and usually included the deities of protection, healing, luck, and honour. Local deities were centered around nature worship, usually a local landscape feature, such as mountains, trees, or rivers. The Celtic pantheon can be roughly divided into the older Gaulish/Brythonic deities, mostly described by Greco-Roman sources, and the Welsh and Irish deities, found in Celtic mythology.
