Mary Lou Ridinger (born 1945 in Fort Worth, Texas) is an American archaeologist. She holds a B.A. in Latin American Studies from the University of Colorado Boulder and an M.A. in Archaeology from the University of the Americas [1] After her graduate studies, Ridinger lived in San Miguel de Allende, Mexico and worked on a number of archeological digs in the country, including the excavation preceding the construction of Mexico City's subway system. She is known for her discovery of in-situ jade quarry sites in Guatemala that had been lost since the time of the Spanish Conquest of the Americas, although a previous discovery of another in-situ jadeite quarry in Guatemala was made by others earlier in the mid 20th-century.

Discovery of Guatemalan Jade Sources

Ridinger may be widely regarded among scholars as the first archaeologist to discover the in-situ locations of the pre-Columbian Maya jadeite jade quarry areas. [2] [3] However, in 1952, the first documented discovery of in-situ jadeite in a pre-Columbian Maya jadeite quarry was made by Robert E. Leslie in the Motagua River valley near Manzanal, Guatemala, as documented in a 1955 publication co-authored by Leslie with William F. Foshag, who, at the time, was Head Curator of the Smithsonian Institution Department of Geology. [4] In 1975, In partnership with her late husband Jay Ridinger, Mary Lou Ridinger discovered three distinct sources for jadeite in the Motagua river valley of Guatemala, and also discovered tools and other indications that pre-Columbian Maya artisans had worked the material at the source site. [5]

In years that followed, Ridinger and her husband discovered new types of jade that had previously been unknown, uncovering in 1987 a dark colored jade with pyrite inclusions now dubbed "Galactic Jade" and followed in 1998 by the discovery of a lavender variety of jadeite. [3]

Jade Enterprise in Guatemala

Jadeite crafts and jewelry is now a staple craft industry in Guatemala. In 1975, Mary Lou and Jay Ridinger opened Jades S.A., the first post-conquest jade workshop in the western hemisphere, and began training stone carvers to work with the very dense mineral. She is recognized by such organizations as The Explorers Club and the Marquis Who's Who as the founder of the modern jade business in Guatemala. Notable figures such as President Bill Clinton and actor Robert Redford have visited her business in Antigua Guatemala and commended her work. Jades S.A. is now frequently visited by foreign dignitaries as well as local government officials and houses a sizeable museum wing illustrating the history and timeline of the use of jadeite by the Maya and pre-Maya inhabitants of Central America.

Public Recognition

She has been featured in National Geographic (Sept 1987 Vol. 172 no.3), [6] the Discovery channel (June 5, 1999, "The Mystery of Jade"), [7] and numerous other publications and media appearances. She and her late husband Jay Ridinger's story has been featured in a recent book, Stone of Kings (2012) by Gerard Helferich. [8]

Philanthropy

In 2008, upon a successful campaign to divert a highway project from running through portions of the Izapa archeological site, Ridinger and her sister Georgeann Johnson founded The Maya Conservancy, [9] a 501c non-profit organization with the stated mission "to aid in the preservation and protection of Maya and Pre-Maya archaeological sites throughout Central America and Mexico, in the preservation and conservation of Maya Cultural Heritage, and in educational guidance and financial assistance to private and governmental bodies in these countries." The Maya Conservancy has notable Maya scholars on its board, such as Dr. David Sedat from the Copan project and Dr. Robert Sitler.

<span class="mw-page-title-main">Jade</span> Ornamental stone, commonly green

Jade is an umbrella term for two different types of decorative rocks used for jewelry or ornaments. Jade is often referred to by either of two different silicate mineral names: nephrite, or jadeite. Nephrite is typically green, although may be yellow, white or black. Jadeite varies from white or near-colorless, through various shades of green, to lavender, yellow, orange, brown and black. Rarely it may be blue. Both of these names refer to their use as gemstones, and each has a mineralogically more specific name. Both the amphibole jade (nephrite) and pyroxene jade are mineral aggregates (rocks) rather than mineral species. Nephrite was deprecated by the International Mineralogical Association as a mineral species name in 1978. The name "nephrite" is mineralogically correct for referring to the rock. Jadeite, is a legitimate mineral species, differing from the pyroxene jade rock. In China, the name jadeite has been replaced with fei cui, the traditional Chinese name for this gem that was in use long before Damour created the name in 1863.

<span class="mw-page-title-main">Jadeite</span> Pyroxene mineral

Jadeite is a pyroxene mineral with composition NaAlSi2O6. It is hard (Mohs hardness of about 6.5 to 7.0), very tough, and dense, with a specific gravity of about 3.4. It is found in a wide range of colors, but is most often found in shades of green or white. Jadeite is formed only in the subduction zones of continental margins, where rock undergoes metamorphism at high pressure but relatively low temperature.

Nakbe is one of the largest early Maya archaeological sites. Nakbe is located in the Mirador Basin, in the Petén region of Guatemala, approximately 13 kilometers south of the largest Maya city of El Mirador. Excavations at Nakbe suggest that habitation began at the site during the Early Formative period and continued to be a large site until its collapse during the Terminal Formative period. The fall of Nakbe and El Mirador took place at roughly the same time.

<span class="mw-page-title-main">Jade use in Mesoamerica</span>

The use of jade in Mesoamerica for symbolic and ideological ritual was highly influenced by its rarity and value among pre-Columbian Mesoamerican cultures, such as the Olmec, the Maya, and the various groups in the Valley of Mexico. Although jade artifacts have been created and prized by many Mesoamerican peoples, the Motagua River valley in Guatemala was previously thought to be the sole source of jadeite in the region.

Sierra de las Minas is a mountain range in eastern Guatemala which extends 130 km west of the Lake Izabal. It is 15–30 km wide and bordered by the valleys of the Polochic River in the north and the Motagua River in the south. Its western border is marked by the Salamá River valley which separates it from the Chuacús mountain range. The highest peak is Cerro Raxón at 3,015 m. The Sierras (Chuacús) rich deposits of jade and marble have been mined for centuries. The small scale mining activities explain the name of the mountain range.

<span class="mw-page-title-main">Talgua caves</span>

Talgua Cave is a cave located in the Olancho Valley in the municipality of Catacamas in northeastern Honduras. The misnomer “The Cave of the Glowing Skulls” was given to the cave because of the way that light reflects off of the calcite deposits found on the skeletal remains found there. The site has gained the interest of archaeologists studying cave burials of Central America and of Mesoamerica as one of the most extensive Early to Middle Pre-Classic ossuary cave sites currently known to have been in contact with the Maya societies of nearby Mesoamerica. It provides many valuable clues to how the inhabitants of the Talgua Cave may have been an important link between Pre-Columbian Mesoamerica and parts further south and east in Central America and extending into those societies in northern South America, a region known as the Isthmo-Colombian Area.

Maya belt plaques were decorative and functional pendants worn by ancient Maya ajawob (rulers) to validate their rulership through referencing major deities and important ancestors. They can be seen as significant elements of the costumes of rulers on stelae and in other representations found in ancient Maya art. These plaques, which hung from belts, were used during rituals to memorialize important events and dates.

Economy is conventionally defined as a function for production and distribution of goods and services by multiple agents within a society and/or geographical place An economy is hierarchical, made up of individuals that aggregate to make larger organizations such as governments and gives value to goods and services. The Maya economy had no universal form of trade exchange other than resources and services that could be provided among groups such as cacao beans and copper bells. Though there is limited archeological evidence to study the trade of perishable goods, it is noteworthy to explore the trade networks of artifacts and other luxury items that were likely transported together.
