TCAS 2019

On Tuesday, May 7th, TCAS is fortunate to have Ron Barber back with us.  The title of Ron’s presentation is:

“Chasing the Plumed Serpents of the Southwest

Ron was born and raised in the oil fields of South America, in small isolated backcountry oil camps.

His parents hauled their kids though the mountains, deserts and jungles; always in search of new adventures.

Encountering indigenous cultures and ancient sites has led to a long-term interest and curiosity about ancient civilizations.

Ron is an explorer by nature, an engineer by profession. He is a mechanical engineer with 39 years at the national laboratories in California and New Mexico.

“Chasing the Plumed Serpents of the Southwest”

The Stone Calendar Project has been studying rock art sites throughout the Southwest and northern Mexico identifying glyphs that record specific times of the year using unique sun light and shadow interactions. We encounter a wide range of glyph images at all of the sites, helping us to identify the cultural origin of the rock art. The plumed and/or horned serpent is found at many sites, up and down the Rio Grande corridor, down into Mexico, and in the Four Cornia region. In some locations the crested serpents appear to have horns, while in others they have both horns and plumes, and in some cases the crest is unclear. The plumed serpent appearance in the southwest has largely been attributed to infusion of the Mesoamerican plumed serpent such as Quetzalcoatl, from the highlands of Mexico. Horned serpents appear early in the Southwest and may have fused together with the plumed serpent to form the horned and plumed serpents seen at discrete locations in the southwest. This presentation will summarize the crest- ed serpent rock art locations and regional styles, and compare them to other mural and ceramic images. Religious practices in the Pueblo World still include the crested ser- pents, and ethnographic records also provide contemporary images for comparisons to prehistoric rock art images.
