AbstractRadiocarbon dates for samples from three buildings at Tikal, Guatemala, the lintel beams of which bear Maya hieroglyphs, are presented. These include dates recently determined at the University of California at Los Angeles and two UCLA and University of Pennsylvania inter-laboratory cross-checks. Two dates from the inner and outer portions of a sapote log have been determined in order to assess the growth rates of the logs from which the temple beams were fashioned and thereby help to explain some of the differences among radiocarbon dates which were previously determined. The dates for samples considered to be reliable continue to support the Goodman-Thompson-Martinez “Correlation B” hypothesis for Temples IV and I, but they also indicate that the previous chronological interpretation of the hieroglyphs of Structure 10 should be revised.

A radiocarbon facility has been installed at the University of California, Riverside (UCR) to support interdisciplinary studies including archaeologic, archaeometric, geophysical, and geologic research. The laboratory was built between 1970 and 1973. Initially, a sample pretreatment and combustion system designed for a proportional CO2 counting system was installed. It was designed after concepts developed at the University of California Los Angeles (UCLA) and New Zealand (Institute of Nuclear Sciences) Laboratories, and began processing samples in November 1972.

The California missions, whose original church spaces and visual programs were produced by Iberian, Mexican, and Native artisans between 1769 and 1823, occupy an ambiguous chronological, geographical, and political space. They occupy lands that have pertained to conflicting territorialities: from Native nations, to New Spain, to Mexico, to the modern multicultural California. The physical and visual landscapes of the missions have been sites of complex and often incongruous religious experiences; historical trauma and romantic vision; Indigenous genocide, exploitation, resistance, and survivance; state building and global enterprise. This Dialogues section brings together critical voices, including especially the voices of California Indian scholars, to interrogate received models for thinking about the art historical legacies of the California missions. Together, the contributing authors move beyond and across borders and promote new decolonial strategies that strive to be responsive to the experience of California Indian communities and nations. This conversation emerges from cross-disciplinary relationships established at a two-day conference, “‘American’ Art and the Legacy of Conquest: Art at California’s Missions in the Global 18th–20th Centuries,” sponsored by the Terra Foundation for American Art and held at the University of California, Los Angeles, in November 2019.
