The retake of the studies about baroque mobilized great part of the Brazilian literary criticism since the 50ths of the Twentieth Century. Through this debate, it is possible to grasp meaningful divergences in the critical and historiographic models, as well as the interested choices involving the oblivion or the valorization of baroque. As long as Antonio Candido silences the baroque in his historiographic landscape of the Brazilian literature formation, due to a certain inappropriate notion of a literary system, Haroldo de Campos lines baroque poetic procedure in a synchronic perspective with the concretist vanguard as a movement of rupture able of renewing the methods of literary composition and reception. The polemic provoked by the sequestration of baroque, therefore, leads to a wider analysis of Antonio Candido and Haroldo de Campos projects of literary historiography, in which to the former it was important to recognize a tradition founded in the self reflected dimension of the author, while to the second one the tradition was settled in a kind ruptures inventory.
