The Atlas of Ancient Rome : biography and portraits of the city
edited by Andrea Carandini with Paolo Carafa ; translated by Andrew Campbell Halavais.
Princeton, New Jersey : Princeton University Press, 
Main Library DG63 .A8513 2017 Vols. 1-2
"The Atlas of Ancient Rome provides a comprehensive archaeological survey of the city of Rome from prehistory to the early medieval period. Lavishly illustrated throughout with full-color maps, drawings, photos, and 3D reconstructions, this magnificent two-volume slipcased edition features the latest discoveries and scholarship, with new descriptions of more than 500 monuments, including the Sanctuary of Vesta, the domus Augusti, and the Mausoleum of Augustus. It is destined to become the standard reference for scholars, students, and anyone interested in the history of the city of Rome. The Atlas of Ancient Rome is monumental in scope. It examines the city's topography and political-administrative divisions, trade and economic production, and social landscape and infrastructure--from residential neighborhoods and gardens to walls, roads, aqueducts, and sewers. It describes the fourteen regions of Rome and the urban history of each in unprecedented detail, and includes profiles and reconstructions of major monuments and works of art. This is the only atlas of the ancient city to incorporate the most current archaeological findings and use the latest mapping technologies."

Map Library Supersize Atlas Case (3 West) G1033 .B3 2000
In 99 full-color maps spread over 175 pages, the Barrington Atlas recreates the entire world of the Greeks and Romans from the British Isles to the Indian subcontinent and deep into North Africa. It spans the territory of more than 75 modern countries. Its large format (13 x 19 ins or 33 x 48 cm) has been custom-designed by the leading cartographic supplier MapQuest.com, Inc., and is unrivalled for range, clarity and detail. Over 70 experts, aided by an equal number of consultants, have worked from satellite-generated aeronautical charts to return the modern landscape to its ancient appearance, and to mark ancient names and features in accordance with the most up-to-date historical scholarship and archaeological discoveries. Chronologically, the Barrington Atlas spans archaic Greece to the Late Roman Empire, and no more than two standard scales (1:500,000 and 1:1,000,000) are used to represent most regions.

The Barrington Atlas includes a CD-ROM Map-by-Map Directory. A separate 1,500 page two-volume print edition of the Directory is also available at $150 / £95. The Directory is designed to provide information about every place or feature in the Barrington Atlas. The section for each map comprises:
(1) a concise text drawing attention to special difficulties in mapping a region, such as extensive landscape change since antiquity, or uneven modern exploration.
(2) a listing of every name and feature on the map, with basic data about the period of occupation, the modern equivalents of ancient placenames, the modern country within which they are located, and brief references to relevant ancient testimony or modern studies.
(3) a bibliography of works cited.
The Map-by-Map Directory is an essential accompaniment to the Barrington Atlas. As a uniquely rich, comprehensive, up-to-date distillation of evidence and scholarship, it has no match elsewhere and opens the way to an immense variety of further research initiatives.
