Abstract
The purpose of this article is to present a historical analysis, the fundamentals of which are found in the concepts of temporality and historicity developed by Martin Heidegger. For this, some aspects of the work Being and Time (Sein und Zeit) are presented and articulated, with the interpretations and considerations of other authors such as Reinhart Kosellek, Hans Ulrich Gumbrecht, Cezar Louis Sebt and Valdei Lopes Araújo. This analysis is intended to contribute to the construction of historiographical categories of temporality and historicity. In the second part of the text, these categories are applied in the analysis of a medieval document of astromagic, translated from Arabic into Spanish and Latin at the court of King Alfonso X of Castile, the Picatrix. It appears that, because it is a "presence-culture” as proposed by Gumbrecht, the medieval society is a rich laboratory for understanding the movement of temporalities and the historical phenomenon of transculturality.
