Tikal Report 27 presents artifacts and associated unworked materials recovered by the University of Pennsylvania Museum's Tikal Project of 1956-1969.

TR27A reports on goods used as markers of social status and goods used in ritual. It describes the splendid ornaments and insignia of jade, shell, pearls, and inscribed bone shown in representations on monuments and pottery vessels and recovered from the burials of Tikal's elites. Each artifact is described in the text, tabulated, and richly illustrated with drawings and photographs. An accompanying CD-ROM includes updated databases for all recovered objects, enabling the reader to discover detailed relationships between artifact, date, and context. It also includes William R. Coe's drafts of reconstructions of destroyed offerings and typologies for ceremonial lithics and shell "Charlie Chaplin" figurines.

This volume draws attention to recent obsidian studies in the Americas and acts as a reference for archaeologists and scholars interested in material culture and exchange. Moreover, it provides a wide range of case studies in obsidian characterization, material application, and theoretical interpretations in the Americas.

A comprehensive series of reconstructed views rendered in colors approximating the original finishes of polished plaster and paint, with 42 different stages of development in three-dimensional form, show what the Acropolis looked like at various times from ca. 330 BCE to CE 600. On an accompanying CD-ROM 112 color plates include constructions of individual structures and some photos of Acropolis fabric at the time of excavation and consolidation. The text accompanying the color plates provides a rationale for the sequences illustrated and an interpretation of ancient Maya intentions in developing the architectural forms that were found, including ideas of rulership and monumental architecture.

The primary question addressed in this book focuses on how the ancient Maya in the northern Petén Basin sustained large populations during the Late Classic period.

This volume describes and illustrates the ceramic figurines excavated at the Maya site of Tikal, Guatemala, from 1956 through 1969. The collection includes both hand modeled and mold-made figures, human and animal, as well as related ceramic objects including figurine molds, flutes, and panpipes. The figurines are classified by subject matter, and the site distribution and dating discussed. These figurines are the largest excavated collection of ceramic figurines from a Maya site, and one of the major artifact categories from the site of Tikal. Most of the classifiable pieces are illustrated at a scale that allows comparison with similar objects from other Maya sites. The purpose of this volume is the presentation of the material from the site of Tikal; comparative material is limited.
