List of Celtic deities
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 deities" and "local deities". "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" that embodied 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. Gaelic deities and characters. Note: Alternative names are shown in brackets. Gaulish and Brythonic deities. The Gaulish Celts inhabited the region corresponding to modern-day France, Switzerland, southern  and western Germany, Belgium, Netherlands, Luxembourg and northern Italy. The Brythonic Celts, or Britons, inhabited most of the island of Great Britain and later migrated to Brittany. Brythonic deities and characters. The Welsh and Cornish are the Britons that inhabit modern-day Wales and Cornwall (). After the Anglo-Saxons invaded Britain, many Brythonic territories came under Anglo-Saxon influence; in Wales, however, Brythonic Celtic religion was largely retained. Many Welsh and especially Cornish myths were later Christianized so it is sometimes difficult to determine if their characters were originally gods, mortals, or historical figures. Dalmatian deities. A female deity named  Carvonia is attested in a votive altar found in the Celeia region. Her name is thought to mean "deer" or "doe", based on similar words in Celtic languages.
