The Celtic deities are known from a variety of sources such as written Celtic mythology, ancient places of worship, statues, engravings, religious objects, as well as place and personal names.
Celtic deities can belong to two categories: general and local. General deities were known by the Celts throughout large regions, and are the gods and goddesses called upon for protection, healing, luck, and honour. The local deities from Celtic nature worship were the spirits of a particular feature of the landscape, such as mountains, trees, or rivers, and thus were generally only known by the locals in the surrounding areas.
After Celtic lands became Christianised, there were attempts by Christian writers to euhemerize or even demonize most of the pre-Christian deities, while a few others became Saints in the church. The Tuatha Dé Danann of Irish mythology, who were commonly interpreted as divinities or deified ancestors, were downgraded in Christian writings to, at best "fallen angels", or mere mortals, or even portrayed as demons.
The Gauls inhabited the region corresponding to modern-day France, Belgium, Switzerland, southern and western Germany, Luxembourg and northern Italy. They spoke Gaulish. The Celtic Britons inhabited most of the island of Great Britain and spoke Common Brittonic or British.
