The Lord of Sipán (El Señor de Sipán) is the name given to the first of several Moche mummies found at Huaca Rajada, Sipán, Peru by archaeologist Walter Alva. The site was discovered in 1987.
Some archaeologists consider this find to be one of the most important archaeological discoveries in South America in the last 30 years, as the main tomb was found intact and untouched by thieves. By 2007, fourteen tombs had been located and identified at Huaca Rajada.
The Royal Tombs Museum of Sipán was constructed in nearby Lambayeque to hold most of the artifacts and interpret the tombs. It opened in 2002 and Dr. Alva is director.
The Moche tombs at Huaca Rajada are located near the town of Sipán in the middle of the Lambayeque Valley. Sipán is in the Zaña district in the northern part of Peru. Close to the coast, it is about 20 miles east of the city of Chiclayo and about 30 miles away from Lambayeque.
Huacas like Huaca Rajada were built by the Moche and other South American cultures as monuments. The Huaca Rajada monument consists of two small adobe pyramids plus a low platform. The platform and one of the pyramids were built before 300 CE by the Moche; the second pyramid at Huaca Rajada was built about 700 CE by a later culture. Many huacas were looted by the Spanish during and after the Spanish conquest of the Inca Empire; the looting of huacas continues to be a problem in many locations.
In early 1987, looters digging at Huaca Rajada found several objects made of gold. A disagreement among the looters caused the find to be reported to the local police. The police raided the site, recovering a number of items, and alerted Dr. Alva.
Scientific analysis of the skeleton of the Lord of Sipán show that he was approximately 1.63 meters tall and was about 35–45 years old at the time of his death. His jewelry and ornaments, which included headdresses, a face mask, a pectoral, (the pectoral was gold and had the head of a man and the body of an octopus) necklaces, nose rings, ear rings and other items, indicate he was of the highest rank. Most of the ornaments were made of gold, silver, copper and semi-precious stones.
