Celtic mythology originates from the ancient Celtic peoples of Europe and is preserved through myths, legends, and later medieval literature. These stories emphasize a deep connection to nature, the spirit world, and the cycles of life. Gods, heroes, fairies, and otherworldly realms play central roles, often blending the human and supernatural. Celtic myths reflect the values, social structures, and spiritual beliefs of early Celtic cultures. Today, they are studied to explore pre-Christian European traditions and their enduring influence on folklore and modern fantasy.
