The Ogooué (or Ogowe), some 1,200 kilometres (700 mi) long, is the principal river of Gabon in west central Africa and the fourth largest river in Africa by volume of discharge, trailing only the Congo, Niger and Zambezi. Its watershed drains nearly the entire country of Gabon, with some tributaries reaching into the Republic of the Congo, Cameroon, and Equatorial Guinea.
The Ogooué River rises in the northwest of the Bateke Plateaux near Kengue, Republic of Congo. It runs northwest, and enters Gabon near Boumango. Poubara Falls are near Maulongo. From Lastoursville until Ndjole, the Ogooué is non-navigable due to rapids. From the latter city, it runs west, and enters the Gulf of Guinea south of Port Gentil. The Ogowe Delta is quite large, about 100 km long and 100 km wide.
The Ogooué Basin is 223,856 square kilometres (86,000 sq mi), of which 173,000 square kilometres (67,000 sq mi) or 73 percent lies within Gabon. It mostly consists of undisturbed rainforest with some savanna grassland where the mid-year dry season is longest. It is home to a high biodiversity. All three species of African crocodile, for instance, occur in the river: the Nile crocodile, the dwarf crocodile, and the slender-snouted crocodile. It is also the type locality for the catfish Synodontis acanthoperca.
Ogun or Ogoun (also spelled Oggun or Ogou; known as Ogún or Ogúm in Latin America) is an Orisha, Loa, and Vodun, who is a warrior and a powerful spirit of metal work. In Santería and Palo, Ogún is syncretized with Saint Peter. In Haitian Vodou, Ogoun is syncretized with St. Jacques Majeur (St. James the Greater) in his incarnation as Santiago Matamoros (St. James the Moorslayer). In Candomblé, Ogúm is syncretized with Saint George or Saint Sebastian.
In Yoruba religion, Ogun is a primordial Orisha who first appeared as a hunter named Tobe Ode. He was the husband of Oya. He is said to be the first Orisha to descend to the realm of Ile Aiye, "Earth", to find suitable place for future human life. In commemoration of this, one of his praise names is Osin Imole or the "first of the primordial Orisha to come to Earth". He is celebrated in places like Ekiti, Oyo, and Ondo States. He is believed by his followers to have wo ile sun, to have disappeared into the earth's surface instead of dying, in a place named Ire-Ekiti. Throughout his earthly life, he is thought to have fought for the people of Ire thus is known also as Onire.
