Which Maya ruler's elaborate tomb was found in Palenque's Temple of the Inscriptions?

The Maya ruler whose elaborate tomb was found in Palenque’s Temple of the Inscriptions was Pakal the Great. His full name is often given as K’inich Janaab’ Pakal, and he ruled the city of Palenque in present-day Chiapas, Mexico, for much of the 7th century.

Pakal became king in 615 CE, when he was only about 12 years old, and ruled until his death in 683 CE. During his reign, Palenque experienced major architectural and artistic development. The Temple of the Inscriptions was completed by his son, K’inich Kan Bahlam II, and served as Pakal’s funerary monument.

Archaeologists discovered Pakal’s richly decorated sarcophagus and burial chamber beneath the temple in 1952. The famous lid shows Pakal in symbolic imagery connected with Maya beliefs about death and rebirth. The tomb is sometimes confused with monuments associated with Lady K’abel, Yax K’uk’ Mo’, or Jasaw Chan K’awiil, but those rulers belonged to other Maya centers or burial traditions.
