Bahian researcher Nina Rodrigues (1862-1906) published seven oral narratives in her book Os africanos no Brasil, published posthumously in 1932, which went on to become a classic. Comparing the folk tales she collected in Salvador and others collected by Sílvio Romero in the state of Sergipe with narratives from the Alfred B. Ellis collection, published in 1894 in the book The Yoruba-Speaking Peoples of the Slave Coast of West Africa, Nina Rodrigues identifies a 'curious equivalence' between many tales from the African tradition and those of European origin (Rodrigues, 1935, p. 315). As was the case with Alexina de Magalhães Pinto's collection, some of the stories recorded by Nina Rodrigues include songs in an African language interlaced with the narrative, as well as a sprinkling of African words in the narrative text itself. At the beginning of the twentieth century, however, not even the storyteller was able to identify the language of the song. As the researcher explains, 'this resulted in a great deal of competition from Creole pronunciation changes' (Rodrigues, 1935, p. 303).
