Narrative bas-reliefs are bas-reliefs depicting stories from mythology or history. Until about the 11th century, the Angkorian Khmer confined their narrative bas-reliefs to the space on the tympana above doorways. The most famous early narrative bas-reliefs are those on the tympana at the 10th-century temple of Banteay Srei, depicting scenes from Hindu mythology as well as scenes from the great works of Indian literature, the Ramayana and the Mahabharata. By the 12th century, however, the Angkorian artists were covering entire walls with narrative scenes in bas-relief. At Angkor Wat, the external gallery wall is covered with some 12,000 or 13,000 square meters of such scenes, some of them historical, some mythological. Similarly, the outer gallery at the Bayon contains extensive bas-reliefs documenting the everyday life of the medieval Khmer as well as historical events from the reign of King Jayavarman VII.
