There is a founding trajectory in the novels of A. Carpentier: the crossing of the Atlantic. The journey from the old to the new world frames a primordial dynamic: a dialogue of cultures, the interculturalism at the center of the novelist’s reflection and imaginary. This paper is an analysis of the fictional characters, particularly the female ones, who, on their Atlantic crossings, undergo a metamorphosis; it focuses, as well, on the black characters who are the protagonists of these crossings. Special attention is given to the ideas which, too, cross the Atlantic, in particular the Baroque, which offered the American continent a new identity and new means of expressing its universality.
