Oxalá is the chief orixá, depicted as a frail old man who walks with a "pachorô" sceptre as a walking stick. Practitioners commonly believe that Olorun tasked him with creating humanity. In some accounts, all of the junior orixás are the children of Oxalá and one of his two wives, Nanã and Iemanjá. This trio are associated with water; Oxalá with fresh water, Nanã with the rain, and Iemanjá with the sea. Other accounts present this cosmogony differently, for instance by claiming that Oxalá fathered all other orixás alone, having created the world from a mingau pudding. An alternative claim among practitioners is that Nanã is the grandmother of Oxalá and the mother of Iemanjá, the latter becoming both mother and wife to Oxalá.
