A look at the sophisticated astronomical knowledge of a pre-Columbian civilization is the topic for the first fall semester talk in Pima Community College’s Speakers’ Series.
Donna Gifford, vice president of online development and instruction, will discuss the solar movement and archeoastronomy in Zapotec ruins in the Oaxacan region of southern Mexico.
The free session on Oct. 2 begins at 6 p.m. in the Community Board Room at the PCC District Office (Building C), 4905 E. Broadway Blvd. Light refreshments will be available.
Gifford will also show slides from a research trip to verify summer solstice markers in Monte Albán and other sites.
