Basque mythology is a collection of ancient beliefs and legends that reflect the region’s deep connection with nature and its unique cultural identity. Rooted in oral tradition, these myths predate the arrival of Christianity and were transmitted through generations, shaping the worldview of the Basque people.
At the core of Basque mythology is Mari, the supreme deity and personification of nature. She is often depicted as a woman who resides in caves or high mountains, such as Anboto and Txindoki. Mari is associated with weather phenomena and justice, rewarding the righteous and punishing dishonesty. She frequently moves between different caves, symbolizing her dominion over the land.

Another significant figure is Sugaar, a serpent or dragon-like being considered Mari’s consort. He is linked to storms and is believed to influence fertility and protection. Together with Mari, he represents the balance of natural forces.
Among the most well-known creatures is the Basajaun, a forest-dwelling giant covered in hair. He is seen as a protector of nature and livestock, warning shepherds of impending danger. The Basajaun is also credited with possessing ancient knowledge of agriculture and blacksmithing, which he indirectly shared with humans.
The Lamia, depicted as beautiful, long-haired women with webbed duck feet, is another key figure. Often associated with rivers and springs, lamias are known for their beauty and supernatural powers. While they can be benevolent, they sometimes test human morality.

The Tartalo, a one-eyed giant similar to the Cyclops of Greek mythology, is a fearsome creature that resides in caves and preys on humans. He is frequently depicted as a symbol of brute force and a challenge to human ingenuity.

Other notable mythological beings include the Galtzagorriak, small mischievous imps that assist in tasks but demand constant work to remain satisfied, and Iratxoak, goblin-like spirits tied to natural elements.
Basque mythology remains an essential part of the region’s folklore, influencing local traditions, place names, and storytelling. While Christianity altered many aspects of these beliefs, the myths have endured, continuing to be celebrated in literature, festivals, and cultural expressions.
