The city was a center of industry. Many potters, jewelers, and craftsmen lived there. Many obsidian artifacts were produced in Teotihuacán. However, no ancient Teotihuacan non-ideographic texts are known to exist (or known to have existed). Mentions of the city in inscriptions from Maya cities show that Teotihuacán nobility travelled to local rulers, as far away as Honduras. It might have conquered them. Maya inscriptions mention an individual nicknamed by scholars as "Spearthrower Owl". He seems to have been a ruler of Teotihuacán, who reigned for over 60 years. He installed his relatives as rulers of Tikal and Uaxactúnin Guatemala Most of what we infer about the culture at Teotihuacán comes from the murals on the site and others, like the Wagner Murals, found in private collections, and from hieroglyphic inscriptions made by the Maya describing their encounters with Teotihuacan conquerors.
