SUMMARY:Archaeology-Hour Screening: Dating Australia's Oldest Rock Art
DESCRIPTION:Please join us for an in-person screening and informal discussion of the Archaeology Hour talk by Helen Green (University of Melbourne). \nAustralia hosts the world’s oldest continuing culture\, and Aboriginal rock art represents one of its most significant records of knowledge. These paintings and engravings remain of deep importance to Aboriginal people today and provide valuable evidence for researchers seeking to understand long-term human-environment interactions. Yet one of the greatest challenges in rock art research is determining age. Without knowing how old the paintings and engravings are\, it is difficult to understand how the artworks relate to past changes in climate\, environment\, or culture. In this talk\, Dr. Helen Green will outline the latest scientific techniques used to establish the age of Australia’s oldest rock art\, and the innovative\, multi-disciplinary projects that bring together traditional Indigenous knowledge and Western science to deepen our understanding of these remarkable cultural records and how we might protect them into the future. \nThis event is free and open to the public.

SUMMARY:Ancient Cities of Guatemala’s Pacific Coast
DESCRIPTION:Free Hybrid Lecture\nAncient Cities of Guatemala’s Pacific Coast\nThursday\, April 2\, 6:00–7:00 pm ET\, Advance registration recommended for in-person and online attendance \n2026 Gordon R. Willey Lecture \nSpeaker: Oswaldo Chinchilla Mazariegos\, Associate Professor of Anthropology\, Yale University \nOn Guatemala’s western Pacific coast\, the region of Escuintla is home to many ancient cities\, and for thousands of years it has been an important crossroads\, drawing traders\, migrants\, and invaders. In this lecture\, archaeologist Oswaldo Chinchilla Mazariegos will present discoveries from three decades of research at the Classic-period cities of Montana and Cotzumalhuapa (250–900 C.E.)\, highlighting how people moved\, interacted\, and recorded their histories along the Pacific coast. The discovery of causeways\, or raised roads\, has revealed the size and organization of these cities\, while refined dating methods have allowed researchers to trace their connections to other urban centers across Mesoamerica. Close study of Cotzumalhuapa’s monumental sculptures has further illuminated these networks through new readings of their intricate reliefs and hieroglyphic texts. Join us to explore how archaeology is reshaping our understanding of Guatemala’s Pacific coast and its place in Mesoamerican history. \nGeological Lecture Hall\, 24 Oxford Street\, Cambridge\, MA. Free admission. Free event parking at the 52 Oxford Street Garage starting at 5:00 pm. Presented by the Peabody Museum of Archaeology & Ethnology and the Harvard Museums of Science and Culture. \nPhoto of Monument 82 from El Baúl\, Cotzumalguapa by Oswaldo Chinchilla Mazariegos
