The city was a center of industry, home to many potters, jewelers, and craftsmen. Teotihuacan is known for producing a great number of obsidian artifacts. No ancient Teotihuacano non-ideographic texts are known to exist (or known to have existed). Inscriptions from Maya cities show that Teotihuacan nobility traveled to, and perhaps conquered, local rulers as far away as Honduras. Maya inscriptions note an individual nicknamed by scholars as "Spearthrower Owl", apparently ruler of Teotihuacan, who reigned for over 60 years and installed his relatives as rulers of Tikal and Uaxactun in Guatemala.
