In Yoruba mythology, Aganju is the Orisha of volcanos, the wilderness, and the river. He is associated with Saint Christopher.
As the third Òrìsà said to have come to earth, Aganjú is an Òrìsà of great antiquity. Lukumi followers of this religion believe that Aganjú is a force that, like the sun that is his symbol, is essential for growth, as well as a cultivator of civilizations. Like the volcano with which he is also associated, he forms the foundation upon which societies are built and is the catalyst for the production of vast amounts of wealth and commerce needed for advanced development. He is most highly regarded by Lukumi practitioners for his role in assisting humans in overcoming great physical as well as psychological barriers. Like the volcano, Aganjú is noted for his legendary strength and his ability to bring about drastic change. His significance in Cuba in the past is most probably due in part to the fact that he was said to have delivered people out of bondage and helped one to carry the heaviest of burdens.
Aganju is heavily associated with Shango, with some stating that he is Shango's father, if not at least his brother. Aganju has been associated with Oshun, with whom he had a relationship, as well as with Yemoja. He is associated with the shoulder and has a strong, powerful, and determined character. Being a recognised member of the deified royal family of old Oyo, he is considered "one heart" with Oya and is received by all of Shango, Oshun and Oya's followers.
