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.

Recently declassified photographs taken by U2 spy planes in the 1950s and 1960s provide an important new source of historical aerial imagery useful for Eurasian archaeology. Like other sources of historical imagery, U2 photos provide a window into the past, before modern agriculture and development destroyed many archaeological sites. U2 imagery is older and in many cases higher resolution than CORONA spy satellite imagery, the other major source of historical imagery for Eurasia, and thus can expand the range of archaeological sites and features that can be studied from an aerial perspective. However, there are significant barriers to finding and retrieving U2 imagery of particular locales, and archaeologists have thus not yet widely used it. In this article, we aim to reduce these barriers by describing the U2 photo dataset and how to access it. We also provide the first spatial index of U2 photos for the Middle East. A brief discussion of archaeological case studies drawn from U2 imagery illustrates its merits and limitations. These case studies include investigations of prehistoric mass-kill hunting traps in eastern Jordan, irrigation systems of the first millennium BC Neo-Assyrian Empire in northern Iraq, and twentieth-century marsh communities in southern Iraq.

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.

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.

The 2001 excavations in Area H on Hamoukar's lower town produced a wealth of information on a residential neighbourhood of a late third-millennium BC city. The excavations were intended to address several issues, including chronology, urban form and the final abandonment of the site. Toward these ends, a broad exposure of over 400 m2 was opened, revealing a prosperous neighbourhood that had been sacked and abruptly abandoned. This report addresses two aspects, its architecture and ceramic assemblage, in detail. The architecture demonstrates broadly shared principles in spatial patterning and planning, as well as similarities in construction, with variations connected to socioeconomic status. The ceramics represent a snapshot of the assemblage of the late or post-Akkadian period, including many whole or reconstructable forms. Contrary to the expectations of abrupt climatic change models, Hamoukar remained settled and urbanised after the proposed 2200 BC Akkadian collapse, and its abandonment was the result of a sudden and violent military event.

The 2003–2006 Suburban Survey at Tell Brak investigated the spatial dimensions of the city's urban origins and evolution via intensive systematic surface survey. This report places this research in the broader context of research on Near Eastern urban origins and development, describes the survey and remote sensing methods and summarises the results, which challenge several long-held models for the timing and geographical origins of urbanism in the Near East. Urbanism at Brak coalesced over the course of several centuries in the late fifth and early fourth millennia BC, when it evolved from a series of spatially discrete settlement zones into a 130-hectare city, without the benefit of irrigated agriculture. Other urban phases occurred in the late third millennium (70 hectare) and in the Late Bronze Age (45 hectare), all with different urban morphologies. Brak's final settlement occurred in the Abbasid period, when a 14-hectare town grew around the Castellum. In addition to the timing, growth and variability of urban form at the site, the Suburban Survey also documented well preserved off-site ancient landscapes of tracks, field systems and irrigation canals.

For many years, the southern Mesopotamia of Ur and Uruk, ancient Sumer, has been seen as the origin centre of civilisation and cities: ‘The urban implosion of late-fourth- and early-third-millennium Mesopotamia resulted in a massive population shift into large sites’ said Nissen in 1988. ‘These new city-states set the pattern for Mesopotamia as the heartland of cities’ (Adams 1981; Yoffee 1998). And for Stone & Zimansky (2005) ‘Remains of the world's first cities are the most noteworthy feature of the landscape in southern Iraq’. But at Tell Brak Joan Oates and her team are turning this model upside down. A long campaign of study, culminating in the new discoveries from 2006 reported here, show that northern Mesopotamia was far along the road to urbanism, as seen in monumentality, industrialisation and prestige goods, by the late fifth millennium BC. The ‘world's earliest cities’ are as likely to have been in north-eastern Syria as southern Iraq, and the model of a core from the south developing a periphery in the north is now ripe for revision.

CORONA satellite photography taken in the 1960s continues to reveal buried ancient landscapes and sequences of landscapes – some of them no longer visible. In this new survey of the Mughan Steppe in north-western Iran, the authors map a ‘signature landscape’ belonging to Sasanian irrigators, and discover that the traces of the nomadic peoples that succeeded them also show up on CORONA – in the form of scoops for animal shelters. The remains of these highly significant pastoralists have been virtually obliterated since the CORONA surveys by a new wave of irrigation farming. Such archaeological evaluation of a landscape has grave implications for the heritage of grassland nomads and the appreciation of their impact on history.

In discussions of the agricultural economies of ancient Mesopotamia, scholars commonly make a sharp distinction between intensive irrigation in the south and extensive rain-fed farming in the north (Weiss 1986; Bagg 2000: 283). In popular as well as academic publications Babylonia is strongly associated with canals, and when one thinks of large state-sponsored initiatives the massive integrated network of canals built by the Sasanian rulers of southern Mesopotamia (Adams 1978) normally springs to mind first. However, since the mid-nineteenth century archaeology and epigraphy have documented the great irrigation schemes of the Neo-Assyrian kings. The inscriptions of Sennacherib in particular refer proudly to his great network of canals, and often describe them in the context of luxurious gardens and parks. The inscriptions make mention of the waters' use for vegetable garden plots and, less frequently, for grain fields above and below Nineveh.

Middle-eastern archaeologists are winning new information from declassified military photographs taken 25 years ago. This study shows how pictures of north-eastern Syria are revealing the routeways, and by inference the agricultural systems of Mesopotamia in the early Bronze Age.

In 1999, the joint expedition of the Syrian Directorate General of Antiquities and the Oriental Institute of the University of Chicago initiated excavations and surface reconnaissance at the site of Tell Hamoukar in the northeastern corner of Hassekeh Province (Figs. 1–2). We need to acknowledge, with gratitude, the help and encouragement rendered by Dr Sultan Muhesen, then Director General of Antiquities, and by Sayyid Abdul Messieh Bagdo, of the Antiquities office in Hassekeh.

McGuire Gibson arrived in Damascus on August 24, 1999 and began to implement logistical arrangements with the co-director, Muhammad Maktash. Actual excavation of the site of Hamoukar began on September 9 and ended on October 31.

Hamoukar has been a subject of interest to a number of scholars through the years because of its size and surface pottery, which includes southern Uruk IV types. The presence of even earlier 4th millennium local Late Chalcolithic pottery as well as Ninevite V and mid-3rd millennium types makes the site crucial in addressing a number of important questions. The complexity of settlement in the early 4th millennium, the nature of the Late Uruk occupation and its relation to other sites with similar material in Syria and Turkey, and the history of the site in the Akkadian and post-Akkadian periods can all be elucidated by excavation here.

The new program of excavations of the Syrian-American Expedition to Tell Hamoukar, Hassake province, northeastern Syria, began with an initial season in Fall 1999. The project includes among its goals the study of the expansion and contraction of settlement on the site, as well as the relationship of the urbanization process on Hamoukar to regional settlement trends. Our initial step was to document the chronology and scale of this process through a controlled surface collection on Tell Hamoukar itself. In addition, we made some initial attempts at documenting the archaeological landscape near the site by recording traces of ancient roads (hollow ways) and making controlled collection of field scatters.
