Temple I (also known as the Temple of Ah Cacao or Temple of the Great Jaguar) is a funerary pyramid dedicated to Jasaw Chan K'awil, who was entombed in the structure in AD 734, the pyramid was completed around 740–750. The temple rises 47 metres high. The massive roofcomb that topped the temple was originally decorated with a giant sculpture of the enthroned king, although little of this decoration survives. The tomb of the king was discovered by Aubrey Trik of the University of Pennsylvania in 1962. Among items recovered from the Late Classic tomb were a large collection of inscribed human and animal bone tubes and strips with sophisticated scenes depicting deities and people, finely carved and rubbed with vermilion, as well as jade and shell ornaments and ceramic vessels filled with offerings of food and drink. The shrine at the summit of the pyramid has three chambers, each behind the next, with the doorways spanned by wooden lintels fashioned from multiple beams. The outermost lintel is plain but the two inner lintels were carved, some of the beams were removed in the 19th century and their location is unknown, while others were taken to museums in Europe. Tikal Temple I is the designation given to one of the major structures at Tikal, one of the largest cities and archaeological sites of the pre-Columbian Maya civilization in Mesoamerica. It is located in the Petén Basin region of northern Guatemala. It also is known as the Temple of the Great Jaguar because of a lintel that represents a king sitting upon a jaguar throne. Another name is the Temple of Ah Cacao, for the ruler buried in the temple. Temple I is a typically Petén-styled limestone stepped pyramid structure that is dated to approximately 732 AD. Situated at the heart of a World Heritage Site, the temple is surmounted by a characteristic roof comb, a distinctive Maya architectural feature. Building Temple I on the eastern side of the Great Plaza was a significant deviation from the established tradition of building funerary temples just north of the plaza in Tikal's North Acropolis.
