The English translation of this standard work of an anthrologist on Brazilian society deviates in title from the exact translation,- ""Big House and Slave Quarters"". In its original, this has gone through four revisions. As a reference tool for students of race and culture, it is an important contribution, but solely, one would think, in that field. Even today there are inescapable traces of the 16th century feudalism, rooted in a slave culture, the outgrowth of harmonious union of culture with culture,- the native, the Portuguese colonist with his mixed antecedents, the Negro. In minute detail, Freyre surveys the contribution made by each,- physical, social, economic. His data is based on study of primary sources; the result, an essay in genetic sociology and social history, as evidenced in significant aspects of the formation of the Brazilian family unit.
