This paper addresses the constituent features of the textual type called memoria, in the context of the legal-administrative sphere of the Colonial Era. This textual type is embedded in both the Spanish and the native American legal tradition, so it is of particular interest for the history of the Spanish language, for the textual linguistics studies and for pragmatics studies. The research also aims to demonstrate that in the Peruvian judicial system of the 16th Century there was a particular type of memoria, modeled by the convergence of the Western way of recording data and the use of quipus as Andean recording medium.
