ABSTRACT Identifying ancient patterns of trade, exchange, and social relations through the tracking of the origin point and final place of deposition of objects is an integral part of archaeological research. Using such information, scholars have constructed elaborate interpretive models to explain the interactions of past societies. The key to success is the correct identification of the original material. In this project, we have undertaken the sourcing of the pipestones utilized by native people living in the Mississippian era in the region between Greater Cahokia and Aztalan in southern Wisconsin to make ear spools. For this research we employed near-infrared spectroscopy, x-ray florescence, and color measurement technology. Our research revealed that the primary source for regional Mississippian ear spools were two distinct variants of Baraboo pipestone from quarries in west-central Wisconsin. The analysis of the Aztalan ear spools and the recent discovery of an ear spool workshop area at the East St. Louis Mound Precinct have expanded our understanding of regional pipestone ear spool manufacture, distribution, and context. Our findings suggest that while Aztalan was enmeshed in a regional network of Baraboo pipestone exchange, Cahokia employed practices that focused on selective targeting for the acquisition of distant exotics.

Pipestones of the midcontinental U.S. have a long history of use by native peoples to craft high status and religious objects, especially pipes, that were often widely exchanged. In this research we describe native use of west central Wisconsin Baraboo Range pipestone as well as identify chemical and mineralogical variation within that formation. The pipestone variants are Baraboo A (dominated by kaolinite, muscovite, and pyrophyllite) and Baraboo B (dominated by pyrophyllite with minor quartz). The recognition of Baraboo pipestone variation allows us to identify previously unsourced pipestone objects. This sourcing project modifies assumptions of Cahokia-centric patterns of earspool manufacture and exchange during the Mississippian period (CE 1000-1400). It demonstrates that Baraboo pipestone Mississippian earspools were quarried, produced, and circulated among a small group of contemporaneous Mississippian societies located in the northern Upper Mississippi River valley — quite outside the Cahokia exchange network. This work establishes that employing rigorous, scientifically sound, and reproducible methodologies to identify the geological source of objects is essential to the interpretation of native interactions.

The Middle Mississippian component at Aztalan was a mixed, Late Woodland / Mississippian occupation sited within a heavily fortified habitation and mound center that is located on a tributary of the Rock River in Wisconsin. It represents the northernmost large Cahokian-related village recorded. The Oneota Lake Koshkonong Locality of the Rock River drainage is located approximately 20 km south of Aztalan, and it consists of a 25 km2 area along the northwest shore with a small cluster of habitation settlements. Sixty-eight radiocarbon measurements have been obtained from Aztalan, and 52 from Oneota settlements in the Lake Koshkonong Locality. We discuss how to best interpret this dataset, and we use Bayesian chronological modeling to analyze these dates. The results suggest that (1) Aztalan's Late Woodland (Kekoskee phase) occupation began in the AD 900s or early AD 1000s, (2) Aztalan's Mississippian occupation ceased in the AD 1200s, (3) Oneota occupations at Lake Koshkonong began after AD 1050 and were established by the AD 1200s, and (4) Oneota occupations at Lake Koshkonong continued after Aztalan's Mississippian abandonment until at least the late AD 1300s. Additionally, the results demonstrate that Aztalan was fortified with a palisade with bastions for much of the Mississippian occupation, suggesting a contested presence in a multiethnic landscape.

Cahokia’s northern hinterland can be conceptualized as extending north from the central Illinois River valley into the western and upper Great Lakes region. The northern tier of this hinterland can be thought of as a region north of the Apple River area of northwest Illinois and south of a line extending east from the mouth of the St. Croix River to the western shore of Lake Michigan. This area includes a wide range of landscapes, biotas, and cultures and this diversity is mirrored in the Cahokia-related manifestations found throughout the region. This chapter provides a brief comparison of three northern tier sites/complexes including Trempealeau, Fred Edwards, and Aztalan in order to highlight the diversity of Mississippian-related occupations in the area.

Altichiero was the dominant north Italian painter of the later Trecento. In Padua, in the 1370s and early 1380s, he worked for patrons close to Petrarch and his circle and perhaps in direct contact with the poet himself. By the time of the second edition of Vasari’s Vite (1568) the memory of Altichiero’s work had suffered significant occlusion, and Vasari’s account of him is little more than an appendix to his life of Carpaccio. Only since the later nineteenth century, and particularly in the last fifty or so years, has Altichiero’s reputation been restored. It is the purpose of this paper to examine aspects of that reputation throughout the century or so after the painter’s death (by April 1393).

Abstract The histories of maize utilization in eastern North America have been substantially revised recently, primarily because of the analysis of charred cooking residues encrusted on pottery. A multifaceted research strategy of bulk δ13C assays coupled with accelerator mass spectrometry radiocarbon data and microbotanical evidence can yield coherent regional maize use histories. Bulk δ13 C assay interpretation complications include (1) variations among vessels by site, (2) a potential for false negatives, and (3) a wide range of variation potentially present for any given time period. Regional histories using this approach can be quite variable without appropriate use of multiple lines of evidence.
