A small room in Xult\u00c3\u00ban indicates that the Mayan calendar goes well beyond 2012.<\/strong><\/p>\n

In 2008, William Saturno, who works at the Archaeology Department at Boston University, US, began a systematic archaeological investigation in the Maya ruins of Xult\u00c3\u00ban, northeastern Guatemala.<\/p>\n

Xult\u00c3\u00ban<\/a> was first reported in 1915, and it is considered the largest unexcavated Maya city. It was until 2010 that a mural painting was found in a structured designated as 10K-2. “Max Chamberlain, one of my undergraduate students found remnants of paint in a looters’ excavation during his lunch hour while doing survey and mapping in the residential areas of Xult\u00c3\u00ban. It was most definitely not a temple. It is a room in what seems a residential context,” says Saturno.<\/p>\n

The archaeologist believes the room might have been used by scribes or calendar priests, the official record keepers of the community who were tightly connected to the kings. According to\u00a0David Stuart, Schele Professor of Mesoamerican Art and Writing at the University of Texas, who deciphered the glyphs, the walls can be compared to a whiteboard in an office where people write possible solutions to problems yet to be resolved.<\/p>\n

This is the first time that archaeologists find a Maya house containing artwork on its walls. The paintings depict men in black uniforms as well as calendrical cycles such as the 260-day ceremonial calendar, the 365-day solar calendar, the 584-day cycle of the planet Venus and the 780-day cycle of Mars.<\/p>\n

“There are tiny glyphs all over the wall, bars and dots presenting columns of numbers. It’s the kind of thing that only appears in one place \u2014 the Dresden Codex, which the Maya wrote many centuries later. We’ve\u00a0never seen anything like it,”\u009d says Stuart.<\/p>\n

The small room (roughly 2 x 2 metres) was built in the 9th century. Its paintings, astronomical tablets created by the local scribe, try to seek harmony between the sky events and sacred rituals.<\/p>\n

“Xult\u00c3\u00ban numbers may have been devised to create schemes for synchronising predictable events connected with the movements of Mars, Venus, the Moon and possibly Mercury. Why these four particular numbers were used, which range in duration from 935 to 6703 years, is uncertain,”\u009d wrote the researchers in a paper published in the May issue of the journal Science<\/a> \u2014 their research was supported by the National Geographic Society.<\/p>\n

The Dresden Codex, a manuscript consisting of 39 sheets inscribed on both sides that contains astronomical calculations, is perhaps the most-well known Maya calendar, but it ends after 13 baktuns<\/a>\u00a0(a baktun is a 144,000-day cycle).\u00a0The codex has caused a lot of speculation about the end of the world, but there is no sign that the Mayan calendar ends in December 2012.<\/p>\n

The numbers painted in Xult\u00c3\u00ban, which predate the codices by some 500 years, reach well beyond 2012. “It’s like the odometer of a car, with the Maya calendar rolling from the 120,000 to 130,000,”\u009d said co-author Anthony Aveni, professor of astronomy and anthropology at Colgate University. “The car gets a step closer to the junkyard as the numbers turn over; the Maya just start over.”\u009d<\/p>\n

Four long numbers on the north wall of the ruined house relate to the Maya calendar and computations about the Moon, Sun and possibly Venus and Mars; the dates stretch some 7,000 years into the future. These are the first calculations Maya archaeologists have found that seem to tabulate all of these cycles in this way. Although they all involve common multiples of key calendrical and astronomical cycles, the exact significance of these particular spans of time is not known.

The 2012 end-of-the-world prediction has caused much controversy. “One number on the wall relates a period of more than 6,700 years, of that is counting forward from the date of the painting then, yes [this paintings contain information well beyond 2012]. The year 2012 doesn’t figure into ancient Maya thought in any way. This is a pop culture phenomenon, not one that would be recognised by the Maya,” says the archaeologist.<\/p>\n

Archaeologist Sylvanus Morley (1833-1948) mapped Xult\u00c3\u00ban, whose name means “\u02dcend rock,’ in the 1920s, and thousands of structures still remain uncounted. “It’s weird that the Xult\u00c3\u00ban finds exist at all”\u00a6 Such writings and artwork on walls don’t preserve well in the Maya lowlands, especially in a house buried only a meter below the surface,”\u009d says Saturno.<\/p>\n

There are many other structures at Xult\u00c3\u00ban, and the Mayanists hope to further explore the structures in the future. Xult\u00c3\u00ban is not as big as Tical, but 99 per cent of its buildings, according to Stuart, are yet to be excavated.<\/p>\n
