Abstract
This paper establishes a relationship between Scorpio and the astronomical group of the Ciudadela at Teotihuacan, linking them to the city's merchant elite. Its argument is based on a brief discussion of the alacrán and the context in which it appears in Prehispanic documents and art. Human figures with a scorpion-tail are emphasized because of their association with the merchant class and Venus. The iconography used to represent this star takes on many shapes, some of which were related to war. The origin of this symbol can be found on the southern coast of Guatemala, from where cacao was distributed to Oaxaca and the highlands. During the Postclassic the Soconusco was one of the most cherished domains of the Aztec, whose pochteca not only carried out long-distance trade but also had the power to solve or promote diplomatic conflicts.
