Praamžius holds a central role in Lithuanian mythology, especially within the creation myths and the structure of the ancient pantheon. His name, translating to "Eternal" or "Primordial", underscores his foundational status in the cosmos and existence. Unlike anthropomorphic depictions common to many mythologies, Praamžius is conceptual, representing universal principles rather than a defined form.

He is often portrayed as the originator of all life, determining destinies while allowing beings to shape their external attributes through their will. In mythological narratives, Praamžius is depicted contending with dark forces like devils (Velnias), nymphs (Laumės), witches, and the selfish, reflecting his role as a guardian of order against chaos.

The mythology situates him as the head of a divine hierarchy, influencing stories about the Sun, his son Perkūnas (the thunder god), the Moon, winds, giants, and other figures. These tales extend into folk traditions such as legends, fairy tales, and songs, revealing Praamžius as the axis of Lithuanian mythological cycles.

Original narratives about Praamžius often incorporate Christian influences, showcasing the syncretism between indigenous beliefs and later religious traditions. He remains a profound symbol of cosmic order and creation in Lithuanian cultural memory.
