Raptor imagery was used to reflect military might in Mesoamerica. A mirror back in the exhibit sports a dart-armed owl found at Teotihuacan. A war shield featuring a similar emblem has been connected to Spearthrower Owl, a Mayan warrior who enjoyed military success in the takeover of Tikal, the catalog reveals.
Karen Petersen published a pictographic dictionary in her book about Plains Indian Art from Fort Marion. She includes a pictograph of an undulating line used to indicate the path taken by a sacred or mysterious object, person, or phenomenon by Fort Marion ledger artists. The Storm God with power over rainfall is depicted in a stucco painting in the Teotihuacan exhibition holding a lightning bolt which similarly undulates. There may be a convention for abstraction that relates the symbols.
