The Pyramid of the Magician (Spanish: Pirámide del adivino) is a Mesoamerican step pyramid located in the ancient, Pre-Columbian city of Uxmal, Mexico. The structure is also referred to as the Pyramid of the Dwarf, Casa el Adivino, and the Pyramid of the Soothsayer. The pyramid is the tallest and most recognizable structure in Uxmal. The Pyramid of the Magician (El Adivino) is the central structure in the Maya ruin complex of Uxmal. The Pyramid of the Magician is also referred to as the Pyramid of the Soothsayer. Uxmal is located in the Puuc region of Mexico and was one of the largest cities on the Yucatán Peninsula. At its height, Uxmal was home to about 25,000 Maya. Like other Puuc sites, the city flourished from 600-1000 AD, with the great building period taking place between 700 and 1000 AD. The name Uxmal means 'thrice-built' in the Mayan language, referring to the many layers of construction of its most imposing structure. The city of Uxmal was designated a UNESCO World Heritage Site in 1996 as it is considered that the ruins of the ceremonial structures represent the pinnacle of late Maya art and architecture in their design, layout and ornamentation. The Pyramid of the Magician dominates the center of the complex and is located at the tourist entrance to the central court. It is positioned on the eastern side of the city, with its western face overlooking the Nunnery Quadrangle and is situated so that its western stairway faces the setting sun at the summer solstice. Construction of the first pyramid temple began in the 6th century AD and the structure was expanded over the next 400 years. The pyramid fell into disrepair after 1000 A.D. and was thereafter looted during the Spanish Conquest of Yucatán. The first detailed account of the rediscovery of the ruins was published by Jean-Frederic Waldeck in 1838. Waldeck’s account of Uxmal inspired John Lloyd Stephens and his illustrator friend, Frederick Catherwood, to make two extended visits to the site in 1839-1841, to record and sketch the layout of the complex. From his notes, Stephens published his now famous Incidents of Travel in the Yucatan. Restoration efforts began in Uxmal in the mid-19th century. The Pyramid of the Magician was regularly repaired and maintained during this period. In the early 1970s, a major conservation project was undertaken by archaeologists from the National Institute of Anthropology and History (INAH). The aim of this effort was to consolidate the sides and flat terraces of the pyramid, and to improve the structural integrity of the temples. In 1988, Hurricane Gilbert swept across the Yucatán Peninsula, bringing high winds and abundant rainfall to the area which caused extensive damage to exterior of the pyramid. A post-hurricane examination of the structure revealed cracks that had developed in the walls of the south side, on both sides of the west stairway. Damage to the vertical walls at the base of the pyramid, on the west side, was also noted. Archaeologists and conservators with the INAH immediately began the process of developing a strategy for conservation and stabilization. The plan called for the strengthening the West façade, monitoring of any structural changes, and implementing emergency measures where needed. The cavity under the base of the stairway was filled with stonework, mortared with concrete and plaster. Movement monitors were placed at critical locations to detect failing integrity. The immediate measures taken to stabilize the pyramid had prevented a catastrophic collapse, but late in 1997, archaeologists noted additional small cracks had developed in the walls of the pyramid (Desmond). Conservation efforts are still underway and, as with El Castillo in Chichen Itza, visitors to the site are now prohibited from climbing the pyramid.
