JADE, OBSIDIAN AND SHELL TREASURES FROM ANCIENT MEXICO

- HELEN SERRAS-HERMAN

TEOTIHUACAN

Imperial green jadeite beads were on display separately as well as on figurines.

Teotihuacan: City of Water, City of Fire was an amazing traveling exhibit with artifacts from the ancient city of Teotihuacan, which is located just outside of Mexico City, in Mexico. The exhibit was held at the Phoenix Museum of Art, from October 2018, through January 27, 2019. It was organized by the de Young Fine Arts Museum in San Francisco and the Los Angeles County Museum of Art, in collaboration with the National Institute of Anthropology and History of Mexico (INAH).

My husband, Andrew and I, took a day trip to Phoenix to witness this fabulous exhibit, which brought together more than 200 artifacts recently discovered, along with others found over a century ago. Exhibited were large-scale sculptures, reliefs, friezes, masks, brightly-colored murals, ceramic vessels, and gemstone carvings crafted in jade and other greenstones, obsidian, alabaster onyx and shell, and stunning jewelry. All these amazing artifacts offered comprehensive insight into the art, everyday life, and religion of Teotihuacan, as well as its trade and influence on other regions of Mexico.

Water and fire were the essential elements that contributed to the power and devastation of the city, and the Teotihuacan art represents manifestations of these natural forces. Hence the exhibit’s name Teotihuacan: City of Water, City of Fire.

Is Earth's Magnetic Field Linked to Atmospheric Oxygen?

The scientists making the observation were surprised. A time series analysis of geological records over the past 540 million years of Earth history seems to show a highly correlated link between oxygen levels in the Earth's atmosphere and the strength of the planet's magnetic field, and both seem to be slowly increasing in sync.

From Waste to Rock in No Time Flat!

Is Subduction “Infectious?”

Earth’s surface is composed of huge plates of relatively stable continental crust and oceanic crust that are constantly forming and recycling. Where they meet, subduction frequently occurs, with ocean crust plunging beneath continents. Thus oceans open and close, appear and disappear.
