This dissertation analyses Jorge Luis Borges’ essay Las kenningar. Looking on his reflexions about the kenningar - a resource typical to the icelandic medieval poetry -, a discussion on language, in general, and on metaphor, in particular, arises. It is shown specifically that an angle explored by Borges allows to think metaphor in a very close way to anthropologist Eduardo Viveiros de Castro’s perspectivism definition as found in his works on Amerindian people life and mind. Such an affinity is fomented by amusing encouters, e.g. if blood in the kenningar can be crows’ beer, to Amerindian people it can be jaguar’s cauim. In both cases, it will be shown that a certain perspective is privileged and that becoming relationships are dominant. All this ocurrs in a specially radical way that promises to subvert the logocentric penchant - which becomes “old stuff” in the contemporary western perceptions about language. It also tries to show how Borges’ essay along with Amerindian perspectivism call for a rethinking of the metaphor/alterity game.
