The Calakmul Epigraphic Research Project, started by the Instituto Nacional de Antropología e Historia (INAH), the primary Mexican archaeological body, in 1993, successfully unearthed an array of Mayan wall murals in Calakmul, Campeche, in south-eastern Mexico, in 2004. This new set, replete with hieroglyphic captions, for the first time offers a glimpse into the daily routine of the Mayan commoners, in and around the time period of 620 to 700 A.D.
