In this article we discuss the archaeological landscapes of the Erbil plain during the Hellenistic period (late fourth century BCE–mid second century BCE) based on the data collected during the Erbil Plain Archaeological Survey (EPAS) between 2012 and 2019. We use a landscape archaeology approach to trace patterns of habitation, migration, land exploitation, and water management from the Iron Age to the early first millennium CE. Over the course of the first millennium BCE, the Erbil plain was transformed from an urbanized core region to a rural area of the vast Seleucid world through a moment of depopulation in the post-Assyrian period. These transformation processes continued after the end of the Hellenistic period, but with a different pattern. Urbanization resumed, peaking during the Parthian (Arsacid) era, when the region was part of the kingdom of Adiabene. Ultimately, our analysis shows how the planned landscape of Assyria was transformed in the centuries that followed the collapse of the empire and how the proximity of political power was the critical variable in the settlement patterns of this part of northern Mesopotamia under the empires of the first millennium BCE.¹

Over the past 25 years, CORONA satellite imagery has become an integral part of archaeological research, especially for arid, sparsely vegetated regions such as the Middle East. Since 2020, a new archive of satellite imagery gathered by the US spy satellite programme that succeeded CORONA—HEXAGON—has become widely available for download via the United States Geological Survey. This photographic archive has enormous potential for archaeological research. Here, the authors seek to lower the barriers to accessing and using this imagery by detailing the background, technical specifications and history of the HEXAGON archive. Four case studies illustrate the benefits and limitations of HEXAGON imagery for archaeological and historical research in the Middle East and beyond.

The Erbil Plain Archaeological Survey (EPAS) investigates settlement and land use from the Neolithic to the present in the Erbil Governorate of the Kurdistan Region of Iraq, which includes a large portion of the core of the Assyrian Empire. In seven field seasons, it has documented a broad settlement landscape in a region of great social and political importance, especially in the Bronze and Iron Ages, including 728 archaeological sites. Its field methodology combines traditional surface collection with the use of historical aerial and satellite photographs, mobile GIS, and UAV (drone) photogrammetry. Preliminary results show some unexpected patterns: a high density of culturally Uruk settlements in the fourth millennium B.C., variable urban morphologies in the Early Bronze Age; and large but low-density settlements at the end of the Sasanian period or the early Islamic period. The project is explicitly testing several hypotheses about centralized Neo-Assyrian landscape planning in the imperial core. These hypotheses appear to be confirmed, although the situation was more complex than in surrounding provinces, probably due to the longer history of continuous settlement.

In this paper, we report the results of our work on automated detection of qanat shafts on the Cold War-era CORONA Satellite Imagery. The increasing quantity of air and space-borne imagery available to archaeologists and the advances in computational science have created an emerging interest in automated archaeological detection. Traditional pattern recognition methods proved to have limited applicability for archaeological prospection, for a variety of reasons, including a high rate of false positives. Since 2012, however, a breakthrough has been made in the field of image recognition through deep learning. We have tested the application of deep convolutional neural networks (CNNs) for automated remote sensing detection of archaeological features. Our case study is the qanat systems of the Erbil Plain in the Kurdistan Region of Iraq. The signature of the underground qanat systems on the remote sensing data are the semi-circular openings of their vertical shafts. We choose to focus on qanat shafts because they are promising targets for pattern recognition and because the richness and the extent of the qanat landscapes cannot be properly captured across vast territories without automated techniques. Our project is the first effort to use automated techniques on historic satellite imagery that takes advantage of neither the spectral imagery resolution nor very high (sub-meter) spatial resolution.

The world's first cities emerged on the plains of Mesopotamia (modern Iraq and Syria) in the fourth millennium bc. Attempts to understand this settlement process have assumed revolutionary social change, the disappearance of kinship as a structuring principle, and the appearance of a rational bureaucracy. Most assume cities and state-level social organization were deliberate functional adaptations to meet the goals of elite members of society, or society as a whole. This study proposes an alternative model. By reviewing indigenous terminology from later historical periods, it proposes that urbanism evolved in the context of a metaphorical extension of the household that represented a creative transformation of a familiar structure. The first cities were unintended consequences of this transformation, which may seem ‘revolutionary’ to archaeologists but did not to their inhabitants. This alternative model calls into question the applicability of terms like ‘urbanism’ and ‘the state’ for early Mesopotamian society.

InThe Economy of Cities, Jane Jacobs conjectured that the world's first cities preceded the origins of agriculture, a proposition that was most recently revived by Peter Taylor in the pages of this journal. Jacobs' idea was out of line with extant archaeological findings when first advanced decades ago, and it remains firmly contradicted by a much fuller corpus of data today. After a review of how and why Jacobs formulated her ‘cities first’ model, we review current archaeological knowledge from the Near East, China and Mesoamerica to document the temporal precedence of agriculture before urbanism in each of these regions. Contrary to the opinions of Jacobs and Taylor, archaeological data are in fact sufficiently robust to reconstruct patterns of diet, settlement and social organization in the past, and to assign dates to the relevant sites. Our response illustrates how generations of archaeological discoveries have yielded solid empirical foundations for the evaluation of wider social scientific debates.

In 2012, the Erbil Plain Archaeological Survey (EPAS) conducted its first season of fieldwork. The project's goal is the complete mapping of the archaeological landscape of Erbil, with an emphasis on the Neo-Assyrian and Hellenistic periods. It will test the hypothesis that the Neo-Assyrian landscape was closely planned. This first report emphasizes the project's field methodology, especially the use of a variety of satellite remote sensing imagery. Our preliminary results suggest that the plain was part of the urbanized world of Mesopotamia, with new cities of the Bronze Age, Iron Age, and Sasanian era identified.
