The Atlantic space referred to until the mid-19th century as the Ethiopic Ocean includes the Southern coast of Senegambia and the Gulf of Guinea, according to historian Luiz Felipe de Alencastro. It was located south of the Meteorological equator, according to the author. It was only with the expansion of steam navigation that the name Atlantic came to encompass both oceanic areas. This is what period maps and nautical references record.
Rio Atlântico thus takes shape as a city that is part of this black ocean. And it was black — or "Ethiopic," a term of Greek origin used to refer to the Black population — because it was Africans, above all moved by compulsion, who most circulated within this oceanic space. And the most intense connections across this sea were linked to the African coast, even when conducted by European vessels.

The intensity of these connections would drive American intellectual Paul Gilroy's formulation of the concept of the Black Atlantic, and this key idea began to shed new light on the subject. The Black Atlantic is a territory in which the histories and culture of this city develop and express themselves, linking up with other shores of the Afro-diasporic Americas.
