Eighteen Rabbit was one of the last rulers of Copán, the thirteenth of a dynasty of sixteen rulers. He was taken as a captive by the ruler of another city. Soon after, between 800 and 900 CE, the population of Copán drifted away and the city was abandoned, much like many other Mayan cities. Mayan hieroglyphs consisted of human, animal, plant, and abstract forms. Where the name of the ruler is not apparent, a prominent feature of the hieroglyphics designates the ruler. This ruler was named for the appearance of a rabbit below the Mayan symbol for the number eighteen among the hieroglyphics on the back of the stele.
