Introduction

After regaining the boundaries of the Middle Assyrian period during the ninth century BCE, the Assyrian empire grew inexorably during the following two centuries. The Assyrian kings campaigned almost yearly, conquering all the regions and kingdoms within or at the natural borders of the empire.Footnote 1 The efficient and fearsome Assyrian army functioned like a well-oiled machine, even in difficult terrain like mountain areas or deserts. The defeated enemies could retain a certain independency as vassals or be annexed to the empire as a province under an Assyrian governor. Babylonia, the southern neighbour of Assyria, represented a special case. After Tiglath-pileser III’s conquest, different rule systems were applied thereFootnote 2 and it was necessary to reconquer the region many times. Babylonia was indeed a problem for various reasons. Without doubt, the weight of its cultural heritage and the respect for it played an important role,Footnote 3 but two other factors were as or even more important: the political situation and the geography.Footnote 4 Babylonia was not a monolithic state but consisted on the one hand of the traditional Babylonian cities, and on the other hand of several AramaeanFootnote 5 and Chaldean tribes.Footnote 6 Furthermore, external actors like Elam or Arabian tribes intervened when alliances were built for or against Assyria.Footnote 7 Moreover, Southern Babylonia was mostly a region of marshes and lagoons, an ideal refuge for rebels. The extensive marshes could become a mortal trap for those who entered the area without knowing it well enough. This region, which represented a severe challenge for the Assyrian army, was called Māt-tâmti, the “Sealand” (Fig. 1). The aim of this paper is to show how this particular landscape was perceived by the Assyrians as well as to point out its decisive role in the development of the historical events.

The Sealand (Māt-tâmti) and the Babylonian marshes.

The Sealand

The term Māt-tâmti is first attested in the Kassite periodFootnote 8 and, according to the Babylonian king-lists, three dynasties ruled there—two in the second and one in the first millennium.Footnote 9 The Sealand is best documented in the first half of the first millennium in AssyrianFootnote 10 as well as in Babylonian sources,Footnote 11 at the time when the interests of this region and those of the Assyrian Empire crossed. In fact, most of the attestations of Māt-tâmti come from Ashurbanipal’s Babylonian correspondence. During this period, the Sealand was closely related to the Chaldean tribe Bīt-Jakīn, whose leaders often ruled over the Sealand as governors.Footnote 12 Marduk-apla-iddina, the archenemy of the Sargonides,Footnote 13 is even referred to in Tiglath-pileser’s inscriptions as king of the Sealand.Footnote 14

We know that the Sealand was located in the southernmost part of Babylonia, roughly in the marshy region east of Ur, but the information about its extent is scarce. It is clear from the sources that the Sealand extended to the Arabian Gulf. In the inscription on Shalmaneser’s throne base concerning his Babylonian campaign on behalf of Marduk-zākir-šumi, when his brother rebelled against him, we read: “I received tribute from the kings of Chaldea as far as the sea (and) imposed my powerful might upon the Sealand”.Footnote 15 Furthermore, Ashurbanipal mentions that his brother Šamaš-šumu-ukīn instigated Babylonians, Chaldeans, Aramaeans and people of the Sealand to rebel against Assyria and gives as borders for the alluded region “from Aqaba to Bāb-salimeti”.Footnote 16 According to Sennacherib’s report on his 6th campaign, Bāb-salimēti was a seaport at the head of the Arabian Gulf.Footnote 17

However, the exact location of the head of the Arabian Gulf at that time is still unknown, and the seashore line cannot be ascertained. After a steady rising for about ten thousand years, the sea-level stabilized around 3500 BCE. It was argued in the past that it was 1–2 m above present levels, and that the sea penetrated about 200 km inlandFootnote 18 (see conjectural coastline in Fig. 1). However, geomorphological studies showed no evidence for such a high sea-level and a consequent large marine gulf that would have extended up to modern Nasiriyah,Footnote 19 confirming the evidence from Sumerian sources, which was not compatible with that shoreline.Footnote 20 Once the sea-level rise decelerated, alluvial sedimentation gradually pushed the coastline to the south to its present position. As the lower Mesopotamian plains are almost flat, the Tigris and the Euphrates tended on the one hand to adopt new river beds (avulsion), and on the other hand to branch into a network of channels (anastomosis).Footnote 21 In the marsh region the twin rivers get almost lost in shallow reed swamps.Footnote 22 Furthermore, in the estuarine zone the tidal effect of the Arabian Gulf is important. The Sealand must therefore have been a mosaic of brackish and fresh marshes, lagoons and intertidal flats.

The marshes in Southern Mesopotamia played an important role in the development of early statesFootnote 23 and were up to the end of the twentieth century the largest wetlands in the Middle East and even in Western Eurasia. They covered in the 1970s a surface of about 15,000 to 20,000 km.Footnote 24 This wetland environment was characterized since historical times by a rich biodiversity, providing a great variety of resources to people living there and a habitat for plants, fish, birds, and wildlife.Footnote 25 This ecosystem was severely destroyed in the 1980s during the Iraq-Iran war, but it was in the 1990s when it almost disappeared as a result of systematic desiccation. During the regime of Saddam Hussein the government drained over 90% of the marshes principally with the military goal of crushing people who lived or took refuge there.Footnote 26 The population shrunk from about 500,000 in the 1950s to 20,000 in 2003.Footnote 27 The desiccation of the marshes changed drastically how Marsh Arabs, and especially women, interacted with their environment with the consequent loss of ancient marsh-specific knowledge and skills.Footnote 28 Their huts and boats for instance show amazing similitudes with those attested in the iconography of ancient Mesopotamia. Nowadays, the Mesopotamian marshland is located mainly in southern Iraq and partially in southwestern Iran and Kuwait.Footnote 29 It comprises three separate, but adjacent marshes: the Hawizeh, the Central and the Hammar Marshes (Fig. 2). Iraq joined the Ramsar Convention on WetlandsFootnote 30 in 2007 and since then the Hawizeh Marsh is a protected site. The two other marshes became protected sites in 2014.Footnote 31

The Sealand in the sources

The ancient sources give some clues as to who lived in the Mesopotamian marshland and what the landscape looked like in the first millennium. Two terms are used in the written sources to refer to the marshland in southern Babylonia: agammu “marsh, swamp”Footnote 32 and appāru “reed marsh, canebrake”.Footnote 33 The Sealand was inhabited by Chaldeans and Aramaeans. Šūzubu (Mušēzib-Marduk), the Chaldean leader of Bīt-Dakkūri, is referred to in Sennacherib’s inscriptions as “a Chaldean who lives among the marshes (agammu)”Footnote 34 and Bīt-Jakīn is described as the land “which is in the marshes (agammu) and canebrakes (appāru)”.Footnote 35 Concerning Bēl-iqīša, the leader of the mighty Aramaean tribe of Gambūlu, Esarhaddon says that his residence “is located twelve leagues distance in water and canebrakes (appāru) like (that of) a fish”.Footnote 36 In a letter addressed to Esarhaddon, Nabû-ušallim, then ruler of Bīt-Dakkūri,Footnote 37 mentions trouble with people living in the marshes (appāru), who are called baṣīhu or maṣīhu “marsh dwellers”.Footnote 38 They were settled in the past in Bīt-Amukāni, the territory of another Chaldean tribe, and they should be resettled, otherwise they will not do the work of the king.Footnote 39

Concerning the geographical distribution of the marshes, there is only little information in the sources. We learn from the report of Sennacherib’s first campaign (late 704–early 702) about the marshes of Guzumānnu, a region in Bīt-Dakkūri. Pursuing Marduk-apla-iddina, who fled there, Sennacherib ordered his warriors “into the midst of marshes and canebrakes”.Footnote 40 Another marsh existed near the city of Saḫrīna according to an epigraph and the corresponding reliefs from room LXX of Sennacherib’s Southwest PalaceFootnote 41: “Sennacherib, king of the world, king of Assyria. The booty of the marshes (agammu) of the city Saḫrīna passed before him”.Footnote 42 Saḫrīna, if identical with Šaḫrinu in the Babylonian sources,Footnote 43 was a city on the Nār-Barsip, between Babylon and Borsippa.Footnote 44 The same city is probably also identical with Ṣaḫrīna, one of the fortresses in Bīt-Dakkūri conquered by Sennacherib during his first campaign.Footnote 45 According to sources from the Neo-Babylonian period there existed also a marsh near Borsippa (Birs Nimrud).Footnote 46 The body of water was so impressive that in the sixth century the morass around Borsippa began to be called tâmtu, the “Sea”.Footnote 47 Layard, who visited Birs Nimrud in late 1849, stressed the extension of the marsh around the site.Footnote 48 In a letter addressed to SargonFootnote 49 a Qatannu marsh is mentioned, probably located near Uruk,Footnote 50 where Puqudeans lived (ša ina appāri Qatannu ašbū).Footnote 51 Furthermore, Nabû-šumu-lēšir, an official active in Babylonia, mentions in a letter to Ashurbanipal that he sent men of Birāte to the “marshy plain of Babylon” (ana sapanni apparu ša Bābili), where they were attacked by supporters of Šamaš-šumu-ukīn.Footnote 52

Although we have no concrete information, at least one great lagoon seems to have existed in the Sealand. The term marratu, which denotes a body of salty water, refers usually—especially in the Neo-Assyrian royal inscriptions—to the Arabian Gulf.Footnote 53 In Shalmaneser III’s inscriptions, it is explicitly explained that the “Sea of Chaldea”, namely the Arabian Gulf, was also called marratu the “Bitter Sea”.Footnote 54 However, as has already been proposed, marratu was also used to denote a lagoon in the Sealand.Footnote 55 It is striking that in Sargon’s inscriptions, Bīt-Jakīn is referred to as the land “at the shore of the Bitter Sea (marratu)”.Footnote 56 Marratu can denote here the Arabian Gulf or a lagoon or both. Moreover, the easternmost border of Tiglath-pileser III’s conquests is described as “from the Bitter Sea (marratu) of Bīt-Jakīn, as far as Mount BikniFootnote 57 in the East”.Footnote 58 Even if the expression “Bitter Sea of Bīt-Jakīn” can be understood as the Arabian Gulf,Footnote 59 an interpretation as a main lagoon in the Sealand is also possible.

Evidence for a lagoon can be found in letters, where the expression bāb marrat “entrance of the Bitter Sea” (literally “mouth of the Bitter Sea”) is used.Footnote 60 From one of the letters sent by Bēl-ibni, military commander of the Sealand, to Ashurbanipal we learn that there existed a fortress (birtu) at the “entrance of the Bitter Sea”.Footnote 61bāb marrat is always written KÁ-ídmar-rat without determinative,Footnote 62 so that the existence of a city called bāb marrat is rather improbable.Footnote 63 In a letter to Esarhaddon, Ubāru, the governor (šakin ṭēmi) of Babylon, writes that the Chaldean chiefs “from Sippar to the entrance of the Bitter Sea” blessed the king as the one who resettled Babylon.Footnote 64 In this case bāb marrat could refer to a lagoonFootnote 65 or to the Arabian Gulf.Footnote 66 However, two letters from Bēl-ibni to Ashurnasirpal point to an interpretation of marratu as lagoon. In one letter, he reports that troops sent by him were attacked 14 miles from the Sealand.Footnote 67 He posted then 600 archers and 50 horsemen at the “entrance of the Bitter Sea” and sent them by rafts (ḫallimu) to the city of Maḫmīti.Footnote 68 They looted there 1500 bulls from Elam and the people of Pillat. 500 of these animals were loaded on rafts and brought back to the Sealand, while the remaining thousand were stabbed and sunk in the “Bitter Sea” (ídmarrat).Footnote 69 As it is highly improbable that 500 bulls could be transported on rafts in the open sea or even near the seashore, the term marratu denotes in this context rather a lagoon in the Sealand.Footnote 70 According to M. Dietrich, a big lagoon divided the Sealand in two parts: a northern part bordering on Elam and Gambūlu and a southern part identical with the marshland southwest of the former channel of the Euphrates.Footnote 71

The lush vegetation of the marshland was not only a source of building materials, principally reeds—as tress would have been less abundantFootnote 72—but also provided a habitat for a variety of game, plants and other natural resources. Written and archaeological sources attest the exploitation of fish, mollusks, wild fowl and turtles from the Ur III periodFootnote 73 and earlier up to the time of Nebuchadnezzar II.Footnote 74 After the submission of Mukīn-zēri of Bīt-Amukkāni in the late years of Tiglath-pileser III’s reign (731–729), the Chaldean king of the Sealand, Marduk-apla-iddina, brought tribute together with other local rulers to Sapīja, the conquered rebel’s capital.Footnote 75 His wealthy tribute is described in detail, showing not only the variety of the natural resources of the marshland, but also attesting overseas trade: “I received as his payment natural, unrefined gold in great quantity, jewelry made of gold, a gold necklace, pearls (literally “precious stones, produce of the sea”), beams of ebony, ellūtu-wood, ašqulalu-plant(s), amīlānu-plant(s), multicolored garments, all types of aromatics, oxen, and sheep and goats”.Footnote 76

The Sealand as hiding place

This particular landscape with its marshes, swamps, canebrakes, lagoons and intertidal flats was much more than a rich natural environment, it was the perfect refuge to hide from pursuers and an excellent base to launch military operations against the Assyrian enemy and its confederates. At the time of Sargon’s accession to the throne (722), Babylonia got lost and Marduk-apla-iddina ruled there for twelve years. In his twelfth regnal year (710), Sargon began the offensive against the usurper. Fearing the Assyrian army, part of the Aramaean population fled to “the Uqnû, a river which was difficult (to reach), and (among) the marshes (qanê api)”.Footnote 77 After the conquest of Dūr-Atḫara, a fortified city in Gambūlu, the Aramaean tribes of Ru’ūa, Ḫindaru, Jadburu, and Puqudu sought also refuge at the Uqnû River.Footnote 78 Sargon blocked the Tupliaš River, built two forts, and starved them out, so that some of the refugees came out and submitted.Footnote 79 During further military operations at the Uqnû, “the place of their concealment” (ašar tapzirtišunu), the environment was systematically destroyed, cutting any access to food, so that the resting refugees submitted to the Assyrian king.Footnote 80 The Uqnû can most probably be identified with the lower course of the Kārūn, which at that time entered the Tigris within the marshland, some 80 km northwest of the place where it joins the Šaṭṭ al-’Arab at present.Footnote 81 During the following years (709–707), Sargon sieged and conquered Dūr-Jakīn, the main stronghold of Bīt-Jakīn.Footnote 82 The annals report that Marduk-apla-iddina escaped, but his hiding place could not be found.Footnote 83 He probably fled into the marshes or to Elam.Footnote 84

Only a few years later, in the accession year of Sennacherib, Marduk-apla-iddina regained once again the throne in Babylonia. He assembled a coalition of Chaldeans, Aramaeans, Babylonians and Elamites—which triggered Sennacherib’s first campaign (late 704–early 702).Footnote 85 When he marched with his army from Cutha to Kish, Marduk-apla-iddina fled, as already mentioned, to the marshes in Guzummānu: “He fled alone and escaped to the land Guzummānu, where he entered the swamp and marshes and (thereby) saved his life”.Footnote 86 Sennacherib’s troops pursued him, but Marduk-apla-iddina could not be captured. We read in the report about this campaign: “For five days they sought him out, but his (hiding) place could not be found”.Footnote 87

Most probably, the marshes also turned out to be an ideal hiding place for Šūzubu, a Chaldean leader of Bīt-Dakkūri, who rebelled against Assyria and some years later would become king of Babylonia under the name of Mušēzib-Marduk (692–689). During his fourth campaign against Bīt-Jakīn (700), Sennacherib defeated Šūzubu, described as “a Chaldean who lives in the marshes”,Footnote 88 and about whom it is said “He fled alone like a lynx and his (hiding) place could not be found”.Footnote 89 Then Sennacherib launched an offensive directly to Bīt-Jakīn, but Marduk-apla-iddina could flee again, this time to a swampy region in Elam. He took the statues of his gods and the bones of his ancestors, left his brothers at the shore of the sea (aḫi tâmtim) and “flew away like a bird to the city of Nagīte-raqqi, which is in the midst of the sea”.Footnote 90 Even if most texts describe the hiding place as an island (ša qabal tâmtim), in one case we read that “he crossed over to the city of Nagītu, which is on the other side of the Bitter Sea (ša ebertānídmarrat). In that place he disappeared”.Footnote 91 Nagītu or Nagīte-raqqi was probably situated on an island in the marshes, either on the eastern side of the lagoon in the Sealand (the ancient equivalent of the Haur al-Ḥammār)Footnote 92 or on the Iranian side of the Arabian Gulf, as might be concluded from the description of Sennacherib’s sixth campaign (see below).

The Sealand and its marshes were also chosen by the Elamite king Tammarītu, who plotted at the side of Šamaš-šuma-ukīn against Ashurbanipal. He was defeated by the Assyrian king and, according to a caption in a collection of epigraphs, he “fled and took the road to the Sealand”.Footnote 93 The following epigraph on the tablet seems to refer to a scene in the marshes, where it was difficult to hide by ship: “the ship of Tammarītu, king of Elam, …, which was mired in the mud flats, swamps, and morass”.Footnote 94

The Sealand as military landscape

The Mesopotamian marshes were not only a place to hide away, but also an ideal base for launching military operations against the Assyrian invaders. During Sennacherib’s eighth campaign (691–late 689), Mušēzib-Marduk, then king of Babylon, rebelled one more time and gathered Aramaean fugitives and criminals around him. Sennacherib’s inscriptions tell us that “they went down to the marshes and incited rebellion”.Footnote 95 The revolt could be subdued, but Mušēzib-Marduk fled again, this time to Elam.Footnote 96

The marshland in southern Babylonia was an extremely difficult terrain for the Assyrian army, not only because the enemy knew the landscape very well and was hard to be found. Moving in the marshes was no simple undertaking anyway, let alone displacing an army through a territory with marshes and lagoons, where firm soil was the exception, especially taking into account that Assyria was no maritime power. In 694, Sennacherib decided to punish the people of Bīt-Jakīn, who took refuge in Elamite territory. The first targets of his sixth campaign were the cities Nagītu and Nagītu-di’bina, which in some inscriptions are described as “cities of the king of Elam whose dwellings are situated on the other shore of the Bitter Sea (ša ina ebertānídmarrati)”.Footnote 97 In this case, there is no doubt that marratu refers to the Arabian Gulf, as in other texts describing the same event, we read that the fugitives of Bīt-Jakīn “crossed the Great Sea of the Rising Sun (tâmtum rabītum ša ṣīt Šamši) and set up their residences in the city of Nagītu of the land Elam”,Footnote 98 being tâmtum rabītum ša ṣīt Šamši one of the names of the Arabian Gulf.Footnote 99

On this occasion, seafaring ships were needed and Sennacherib let them build and sail by skilled Phoenician shipbuilders and mariners.Footnote 100 The ships were built in Nineveh and first sailed down the Tigris up to Opis. From there, they were dragged by land to Sippar and guided into the Araḫtu canal, from where they were sailed further downstream to the canal of Bīt-Dakkūri. Finally, they were sailed down the Euphrates to Bāb-salimeti, not far from the shore of the Arabian Gulf. A very complicated procedure indeed, which was closely followed by the king … from the land. From Sennacherib’s report we learn about the effect of the tide in this southernmost part of the Sealand: “The high tide of the sea rose mightily, and (then) entered my tent and completely surrounded my entire camp. For five days and nights, on the account of the strong water, all of my soldiers had to sit curled up as though they were in cages”.Footnote 101 Finally the ships “reached the marshy area at the mouth of the river, where the Euphrates debouches its water into the roiling sea”.Footnote 102 Sennacherib remained at the shore, where he made sacrifices and let his ships sail across the Gulf.Footnote 103 The campaign was a success and the ships returned to Bāb-salimeti with rich booty and many captives.Footnote 104 It is interesting to remark that the disembarkation on the opposite shore of the Gulf, probably also a marshy landscape, was difficult. The shore of the roiling sea is described as “unsuitable and very difficult (for ships) to dock, horses to climb, and men to set foot on”.Footnote 105

According to the correspondence of Bēl-ibni, the military commander of the Sealand, who was loyal to Ashurbanipal, we learn that boats or rafts were used for operations in the marshes and the lagoon. Rafts (ḫallimu) were used, for instance to transport Bēl-ibni’s troops from the “entrance of the Bitter Sea” to the city of Maḫmīti and to bring them back with 500 bulls.Footnote 106 Another letter reports that Nabû-bēl-šumāti, the grandson of Marduk-apla-iddina, attacked Bēl-ibni, sending troops with rafts (ḫallimu). Bēl-ibni’s counteroffensive was undertaken by 400 archers sent to enemy territory with ships (eleppāte) which crossed the lagoon (or the Gulf?) to Elam.Footnote 107 In another case, Bēl ibni reports that Nabû-bēl-šumāte’s attacks were done with few troops. He asks Ashurbanipal for 70 logs to be floated up to Opis and from there to be brought in direction of the sea to Kār-Nanâ; he also asks for 20 Sidonians to build the ships (eleppāte).Footnote 108 These vessels were not mere boats or rafts, but probably seagoing ships; if they were used for operations across the Gulf or just in the lagoon remains an open question.Footnote 109

Further evidence for the Sealand and its marshy landscape comes from the iconographical material, namely the palace reliefs. The scenes depicting military actions in the marshes confirm the information of the written sources and give a vivid image of the landscape and the dramatic events that happened there. A slab from Room LXX of Sennacherib’s Southwest Palace shows a battle in a marshFootnote 110 (Fig. 3). The historical context is known as the adjoining slabsFootnote 111 show a grove of palm-trees, where Sennacherib standing in his chariot receives the prisoners and the heads of the slain. An already mentioned epigraph labels the scene as “the booty from the marshes of Saḫrīna”.Footnote 112 As has been said, this room was most probably decorated with scenes of Sennacherib’s first campaign. We see the two main features of the Sealand: the canebrakes and the water, where fishes and eels can be perceived. The Assyrian soldiers are depicted on boats with slightly upturned prow, made of bundles of reeds tied together with bands.Footnote 113 Boats navigating toward the left show warriors still shooting arrows. Boats navigating toward the right show soldiers bringing captives to the shore. One of these boats is towed by a man swimming over an inflated skin. The beheaded corpses of defeated enemies floating in the water complete the scene.

Two other slabs from court LXIV show a similar scene, but cannot definitely be linked with one of Sennacherib’s Babylonian campaignsFootnote 114 (Fig. 4). The battle scene is bordered by canebrakes, which are traversed by small watercourses. In this case, six flat-bottomed reed boats are depicted, three of them are manned by Assyrian soldiers shooting arrows on three other boats, where native archers and women are shown. The construction type of the boats is the same as on the slabs from room LXX, but the Assyrian ones are longerFootnote 115 and punted from the stern. At the top, a row of prisoners is conducted to the right by Assyrian soldiers. At the bottom of slab 7, another row of male and female captives is depicted advancing towards the right. Also of interest are the Assyrian horsemen, who scour the canebrakes for hidden enemies. The picture shows clearly that the marshland consisted of canebrakes traversed by channels and also of larger bodies of water, probably not too deep, but at least in some cases deep enough to allow the use of watercraft.

An even more lively and detailed picture of a battle in the marshes of southern Babylonia dates from the reign of Ashurbanipal and comes from room XXVIII of the Southwest Palace, one of the rooms which was redecorated after the reign of SennacheribFootnote 116 (Fig. 5). The scene shows again Assyrian soldiers fighting or transporting prisoners to the shore on reed boats.Footnote 117 The boats are of the same type as in Sennacherib’s reliefs and their light structure is revealed by a detail on the right showing the disembarkation of prisoners: the boat could be held by one soldier. Most of the vessels of the marsh dwellers are hidden in the canebrakes, pressing the reeds under their weight. Some vessels are flat rafts made also of reeds tied together with bands. The hidden men and women are sitting on the rafts, hoping not to be discovered by the Assyrians. Some of them are shooting arrows, taking advantage of the surprise effect, which at the same time revealed their hiding place. As in the other depictions, prisoners are conducted to the palm groves by Assyrian soldiers.Footnote 118 Further reliefs from room F in Ashurbanipal’s North Palace in Nineveh show Elamite people taking refuge in the marshes after the conquest of the city of ḪamānuFootnote 119 during Ashurbanipal’s second campaign against Ummanaldasi (647/6).Footnote 120

The Sealand as a contested space

The Sealand, a region of marshes, swamps, lagoons, and intertidal flats was the setting of fighting between the Assyrian army and marsh dwellers who rebelled against the imperial power. It was an ideal hiding place for fugitives, who, as well as those living there, knew the terrain very well. For the mighty Assyrian army it was a difficult terrain, so that the struggles extended for a long time. The Sealand and its most famous rebel Marduk-apla-iddina could resist for many years, in great part thanks to this particular landscape. Both environment and rebels were thorns in the flesh of the most powerful Assyrian kings from Sargon to Ashurbanipal. Given the difficulties that the marshlands created for the Assyrian army to go through, let alone control, the strategic implications of the marshlands—at least in terms of military and political control, but also possibly in terms of resources—for the Assyrian state were huge.

More work on this theme is needed, but perhaps we get a glimpse of this importance of the Sealand for the Assyrian state, when we consider that the marshland in southern Babylonia fascinated at least one of the Sargonides to such an extent that he reproduced this exotic landscape in the homeland. Around 699,Footnote 121 only a few months after his second Babylonian campaign (700), Sennacherib created an artificial swamp to regulate the surplus water of his first canal system, which was probably located near NinevehFootnote 122: “I created a marsh (agammu) to moderate the flow of water for those gardens and planted a canebrake (ṣuṣû) in it. I let loose in it herons, wild boars, and roe deer. … The marshes (appāru) thrived greatly. Birds of the heavens, herons, made nests and wild boars and roe deer gave birth in abundance”.Footnote 123

This nature reserve was depicted on wall reliefs from court VI in Sennacherib’s Southwest PalaceFootnote 124 and also on those fallen from room S in Ashurbanipal’s North Palace.Footnote 125 Sennacherib also says that he cut off reed from his marsh and used it as building material for his palaces.Footnote 126 Sennacherib’s description of the artificial marsh and the depicted scenes convey a peaceful atmosphere which contrasts with a furious Ashurbanipal when he wrote to Bēl-ibni: “Go to the Sealand … and kill them all!”.Footnote 127
