In the conception of Bluteau, the study it identifies to umsignificativo addition in relation the construction of the literary activity comoforma of knowledge and the entailing of the term literature to a set deobras, not yet congregated for aesthetic or formal affinities, but sobretudopor its nature of territorial and secular, resultant production in movement, however, the definition continued vacant and ample. Following the studies of Barbosa Axe, author dBiblioteca Lusitana, Abreu (2000) it puts for reflection the thought of the mencionadoautor and defender of the idea of that ' ' optimum literary work is that one quecompila, pointing that the library is, par excellence, great produtoraliterria' '. Its work was basically based at its time noagrupamento of printed matters in specific categories, such as: rhetoric, oratria, poetical, philosophy and history. Thick way, we can conclude that, nBiblioteca Lusitana, did not blunt no study of bigger impact or same more appropriate umareflexo on the construction of a conceptual base for aliteratura. According to Abreu (2000), the author of the Lusitana Library anchors seutrabalho in them pillars of a recognized tradition that only intervenes of formaequivocada and confused, data the classification criteria and organization dasprodues in general. All these attempts to appraise literature do not foramem go in view of that the moment of its constitutions was momentosvoltados for history, until understood there as the history of the customs, daslegislaes, of the illustrious men, the religion, etc. Slowly the literature concept go if tornandoespecfico of the aesthetic compositions, the example of the conceived poetry as privileged linguistic umamodalidade for the proper form, content, improvement, election and refinement to vocabular. The movement of history starts to be enclosed and absorvidopela literature during successive centuries of productions writings without, noentanto, to provide concern to become specific the grouping of obrassegundo proper characters of artistic making as they perceive some tericoscom passing of the time, still by means of a process of indefinies eimprecises given the form as, of beginning, were understood.
