Freyre's most widely known work is "The Masters and the Slaves" (Casa-Grande & Senzala, 1933). This is a revolutionary work for the study of races and cultures in Brazil, written in a quite personal and impressionistic tone. The book is a turning point in the analysis of the black heritage in Brazil, which is highly extolled by Freyre. His effort both to rehabilitate the black culture and identify Brazil as a conciliatory country is comparable to the ones of other Latin American writers, such as Fernando Ortiz in Cuba ("Contrapunteo Cubano de Tobacco y Azúcar", 1940), and José Vasconcelos in Mexico ("La Raza Cosmica", 1926).
