Abstract
This article seeks to present the foundations in Foucault’s thought that led him to elaborate the concept of archeology and, in addition, try to recognize its limits. To achieve this, we present his main theoretical dialogues at the beginning of his investigations and the reasons that made necessary to reframe that concept later. Among the conclusions of this study, we suggest that the allegorical conception of language, that was sustained over the period, is formally similar to the structure of metaphysical thought and, as such, is abandoned by Foucault as an attempt to create an original philosophical reflection
