Astronomical magnitudes in the Santa María la Asunción codex

Abstract

Abstract:-In this document are the results of the research to the codex Santa María la Asunción y Vergara, it contains the plots of land that are located in the acolhua region of Texcoco, Mexico. The plots show their perimeter size in T units. It is important that the size of length and area correspond both to the astronomical dimensions of the planet movements that astronomical acolhuas people observed regularly. The planetary revolutions establish correlations between them, which determine a control of their own movements. It also presents the twentieth-thirteenth numeric system, which supports the activities that allowed the measurement of lots, astronomical observations and building monuments. This research was developed from a multidisciplinary vision highlighting astronomy, mathematics (arithmetic and elementary geometry) and surveying.
