Babylonia

Mesopotamia had already enjoyed a long history before the emergence of Babylon, with Sumerian civilization emerging in the region c. 5400 BC, and the Akkadian-speakers who would go on to form Akkad, Assyria, and Babylonia appearing somewhere between the 35th and 30th century BC.

During the 3rd millennium BC, an intimate cultural symbiosis occurred between Sumerian and Akkadian-speakers, which included widespread bilingualism. The influence of Sumerian on Akkadian and vice versa is evident in all areas, from lexical borrowing on a massive scale, to syntactic, morphological, and phonological convergence. This has prompted scholars to refer to Sumerian and Akkadian in the third millennium as a sprachbund.

Akkadian gradually replaced Sumerian as the spoken language of Mesopotamia somewhere around the turn of the third and the second millennium BC (the precise timeframe being a matter of debate). From c. 5400 BC until the rise of the Akkadian Empire in the 24th century BC, Mesopotamia had been dominated by largely Sumerian cities and city states, such as Ur, Lagash, Uruk, Kish, Isin, Larsa, Adab, Eridu, Gasur, Assur, Hamazi, Akshak, Arbela and Umma, although Semitic Akkadian names began to appear on the king lists of some of these states (such as Eshnunna and Assyria) between the 29th and 25th centuries BC. Traditionally, the major religious center of all Mesopotamia was the city of Nippur where the god Enlil was supreme, and it would remain so until replaced by Babylon during the reign of Hammurabi in the mid-18th century BC. The Akkadian Empire (2334–2154 BC) saw the Akkadian Semites and Sumerians of Mesopotamia unite under one rule, and the Akkadians fully attain ascendancy over the Sumerians and indeed come to dominate much of the ancient Near East. The empire eventually disintegrated due to economic decline, climate change, and civil war, followed by attacks by the language isolate speaking Gutians from the Zagros Mountains to the northeast. Sumer rose up again with the Third Dynasty of Ur (Neo-Sumerian Empire) in the late 22nd century BC, and ejected the Gutians from southern Mesopotamia in 2161 BC as suggested by surviving tablets and astronomy simulations. They also seem to have gained ascendancy over much of the territory of the Akkadian speaking kings of Assyria in northern Mesopotamia for a time.

Followed by the collapse of the Sumerian "Ur-III" dynasty at the hands of the Elamites in 2002 BC, the Amorites, a foreign Northwest Semitic-speaking people, began to migrate into southern Mesopotamia from the northern Levant, gradually gaining control over most of southern Mesopotamia, where they formed a series of small kingdoms, while the Assyrians reasserted their independence in the north. The states of the south were unable to stem the Amorite advance, and for a time may have relied on their fellow Akkadians in Assyria for protection.

King Ilu-shuma (c. 2008–1975 BC) of the Old Assyrian period (2025–1750 BC) in a known inscription describes his exploits to the south as follows:

The freedom of the Akkadians and their children I established. I purified their copper. I established their freedom from the border of the marshes and Ur and Nippur, Awal, and Kish, Der of the goddess Ishtar, as far as the City of (Ashur). Past scholars originally extrapolated from this text that it means he defeated the invading Amorites to the south and Elamites to the east, but there is no explicit record of that, and some scholars believe the Assyrian kings were merely giving preferential trade agreements to the south.

These policies, whether military, economic or both, were continued by his successors Erishum I and Ikunum.

However, when Sargon I (1920–1881 BC) succeeded as king in Assyria in 1920 BC, he eventually withdrew Assyria from the region, preferring to concentrate on continuing the vigorous expansion of Assyrian colonies in Anatolia at the expense of the Hurrians and Hattians and the Amorite inhabited Levant, and eventually southern Mesopotamia fell to the Amorites. During the first centuries of what is called the "Amorite period", the most powerful city-states in the south were Isin, Eshnunna and Larsa, together with Assyria in the north.

Around 1894 BC, an Amorite chieftain named Sumu-abum appropriated a tract of land which included the then relatively small city of Babylon from the neighbouring minor city-state of Kazallu, of which it had initially been a territory, turning his newly acquired lands into a state in its own right. His reign was concerned with establishing statehood amongst a sea of other minor city-states and kingdoms in the region. However, Sumu-abum appears never to have bothered to give himself the title of King of Babylon, suggesting that Babylon itself was still only a minor town or city, and not worthy of kingship.

He was followed by Sumu-la-El, Sabium, and Apil-Sin, each of whom ruled in the same vague manner as Sumu-abum, with no reference to kingship of Babylon itself being made in any written records of the time. Sin-Muballit was the first of these Amorite rulers to be regarded officially as a king of Babylon, and then on only one single clay tablet. Under these kings, Babylonia remained a small nation which controlled very little territory, and was overshadowed by neighbouring kingdoms that were both older, larger, and more powerful, such as Isin, Larsa, Assyria to the north and Elam to the east in ancient Iran. The Elamites occupied huge swathes of southern Mesopotamia, and the early Amorite rulers were largely held in vassalage to Elam.

Babylon remained a minor town in a small state until the reign of its sixth Amorite ruler, Hammurabi, during 1792–1750 BC (or c. 1728–1686 BC in the short chronology). He conducted major building work in Babylon, expanding it from a small town into a great city worthy of kingship. A very efficient ruler, he established a bureaucracy, with taxation and centralized government. Hammurabi freed Babylon from Elamite dominance, and indeed drove the Elamites from southern Mesopotamia entirely, invading Elam itself. He then systematically conquered southern Mesopotamia, including the cities of Isin, Larsa, Eshnunna, Kish, Lagash, Nippur, Borsippa, Ur, Uruk, Umma, Adab, Sippar, Rapiqum, and Eridu. His conquests gave the region stability after turbulent times, and coalesced the patchwork of small states into a single nation; it is only from the time of Hammurabi that southern Mesopotamia acquired the name Babylonia.

Hammurabi turned his disciplined armies eastwards and invaded the region which a thousand years later became Iran, conquering Elam, Gutium, Lullubi, Turukku and Kassites. To the west, he conquered the Amorite states of the Levant (modern Syria and Jordan) including the powerful kingdoms of Mari and Yamhad.

Hammurabi then entered into a protracted war with the Old Assyrian Empire for control of Mesopotamia and dominance of the Near East. Assyria had extended control over much of the Hurrian and Hattian parts of southeast Anatolia from the 21st century BC, and from the latter part of the 20th century BC had asserted itself over the northeast Levant and central Mesopotamia. After a protracted struggle over decades with the powerful Kingdom of Upper Mesopotamia kings Shamshi-Adad I and Ishme-Dagan I, Hammurabi forced their successor Mut-Ashkur to pay tribute to Babylon c. 1751 BC, giving Babylonia control over Assyria's centuries-old Hattian and Hurrian colonies in Anatolia.

One of Hammurabi's most important and lasting works was the compilation of the Babylonian law code, which improved the much earlier codes of Sumer, Akkad and Assyria. This was made by order of Hammurabi after the expulsion of the Elamites and the settlement of his kingdom. In 1901, a copy of the Code of Hammurabi was discovered on a stele by Jacques de Morgan and Jean-Vincent Scheil at Susa in Elam, where it had later been taken as plunder. That copy is now in the Louvre.

From before 3000 BC until the reign of Hammurabi, the major cultural and religious center of southern Mesopotamia had been the ancient city of Nippur, where the god Enlil was supreme. Hammurabi transferred this dominance to Babylon, making Marduk supreme in the pantheon of southern Mesopotamia (with the god Ashur, and to some degree Ishtar, remaining the long-dominant deity in northern Mesopotamian Assyria). The city of Babylon became known as a "holy city" where any legitimate ruler of southern Mesopotamia had to be crowned, and the city was also revered by Assyria for these religious reasons. Hammurabi turned what had previously been a minor administrative town into a large, powerful and influential city, extended its rule over the entirety of southern Mesopotamia, and erected a number of buildings.

The Amorite-ruled Babylonians, like their predecessor states, engaged in regular trade with the Amorite and Canaanite city-states to the west, with Babylonian officials or troops sometimes passing to the Levant and Canaan, and Amorite merchants operating freely throughout Mesopotamia. The Babylonian monarchy's western connections remained strong for quite some time. Ammi-Ditana, great-grandson of Hammurabi, still titled himself "king of the land of the Amorites". Ammi-Ditana's father and son also bore Amorite names: Abi-Eshuh and Ammi-Saduqa.

Southern Mesopotamia had no natural, defensible boundaries, making it vulnerable to attack. After the death of Hammurabi, his empire began to disintegrate rapidly. Under his successor Samsu-iluna (1749–1712 BC) the far south of Mesopotamia was lost to a native Akkadian-speaking king Ilum-ma-ili who ejected the Amorite-ruled Babylonians. The south became the native Sealand Dynasty, remaining free of Babylon for the next 272 years.

Both the Babylonians and their Amorite rulers were driven from Assyria to the north by an Assyrian-Akkadian governor named Puzur-Sin c. 1740 BC, who regarded king Mut-Ashkur as both a foreign Amorite and a former lackey of Babylon. After six years of civil war in Assyria, a native king named Adasi seized power c. 1735 BC, and went on to appropriate former Babylonian and Amorite territory in central Mesopotamia, as did his successor Bel-bani.

Amorite rule survived in a much reduced Babylon, Samshu-iluna's successor Abi-Eshuh made a vain attempt to recapture the Sealand Dynasty for Babylon, but met defeat at the hands of king Damqi-ilishu II. By the end of his reign Babylonia had shrunk to the small and relatively weak nation it had been upon its foundation, although the city itself was far larger and opulent than the small town it had been prior to the rise of Hammurabi.

He was followed by Ammi-Ditana and then Ammi-Saduqa, both of whom were in too weak a position to make any attempt to regain the many territories lost after the death of Hammurabi, contenting themselves with peaceful building projects in Babylon itself.

Samsu-Ditana was to be the last Amorite ruler of Babylon. Early in his reign he came under pressure from the Kassites, a people speaking an apparent language isolate originating in the mountains of what is today northwest Iran. Babylon was then attacked by the Indo-European-speaking, Anatolia-based Hittites in 1595 BC. Shamshu-Ditana was overthrown following the "sack of Babylon" by the Hittite king Mursili I. The Hittites did not remain for long, but the destruction wrought by them finally enabled their Kassite allies to gain control.

The date of the sack of Babylon by the Hittites under king Mursili I is considered crucial to the various calculations of the early chronology of the ancient Near East, as it is taken as a fixed point in the discussion. Suggestions for its precise date vary by as much as 230 years, corresponding to the uncertainty regarding the length of the "Dark Age" of the much later Late Bronze Age collapse, resulting in the shift of the entire Bronze Age chronology of Mesopotamia with regard to the Egyptian chronology.

Bronze Age to Early Iron Age Mesopotamian culture is sometimes summarized as "Assyro-Babylonian", because of the close ethnic, linguistic and cultural interdependence of the two political centers. The term "Babylonia", especially in writings from around the early 20th century, was formerly used to also include Southern Mesopotamia's earliest pre-Babylonian history, and not only in reference to the later city-state of Babylon proper. This geographic usage of the name "Babylonia" has generally been replaced by the more accurate term Sumer or Sumero-Akkadian in more recent writing, referring to the pre-Assyro-Babylonian Mesopotamian civilization.

In Babylonia, an abundance of clay, and lack of stone, led to greater use of mudbrick; Babylonian, Sumerian and Assyrian temples were massive structures of crude brick which were supported by buttresses, the rain being carried off by drains. One such drain at Ur was made of lead. The use of brick led to the early development of the pilaster and column, and of frescoes and enameled tiles. The walls were brilliantly coloured, and sometimes plated with zinc or gold, as well as with tiles. Painted terracotta cones for torches were also embedded in the plaster. In Babylonia, in place of the relief, there was greater use of three-dimensional figures—the earliest examples being the Statues of Gudea, that are realistic if somewhat clumsy. The paucity of stone in Babylonia made every pebble precious, and led to a high perfection in the art of gem-cutting.

Tablets dating back to the Old Babylonian period document the application of mathematics to the variation in the length of daylight over a solar year. Centuries of Babylonian observations of celestial phenomena are recorded in the series of cuneiform script tablets known as the 'Enūma Anu Enlil'. The oldest significant astronomical text that we possess is Tablet 63 of 'Enūma Anu Enlil', the Venus tablet of Ammi-Saduqa, which lists the first and last visible risings of Venus over a period of about 21 years and is the earliest evidence that the phenomena of a planet were recognized as periodic. The oldest rectangular astrolabe dates back to Babylonia c. 1100 BC. The MUL.APIN, contains catalogues of stars and constellations as well as schemes for predicting heliacal risings and the settings of the planets, lengths of daylight measured by a water clock, gnomon, shadows, and intercalations. The Babylonian GU text arranges stars in 'strings' that lie along declination circles and thus measure right-ascensions or time-intervals, and also employs the stars of the zenith, which are also separated by given right-ascensional differences.

We find [medical semiotics] in a whole constellation of disciplines. ... There was a real common ground among these [Babylonian] forms of knowledge ... an approach involving analysis of particular cases, constructed only through traces, symptoms, hints. ... In short, we can speak about a symptomatic or divinatory [or conjectural] paradigm which could be oriented toward past present or future, depending on the form of knowledge called upon. Toward future ... that was the medical science of symptoms, with its double character, diagnostic, explaining past and present, and prognostic, suggesting likely future. ...

The oldest Babylonian (i.e., Akkadian) texts on medicine date back to the First Babylonian dynasty in the first half of the 2nd millennium BC although the earliest medical prescriptions appear in Sumerian during the Third Dynasty of Ur period. The most extensive Babylonian medical text, however, is the Diagnostic Handbook written by the ummânū, or chief scholar, Esagil-kin-apli of Borsippa, during the reign of the Babylonian king Adad-apla-iddina (1069–1046 BC).

Along with contemporary ancient Egyptian medicine, the Babylonians introduced the concepts of diagnosis, prognosis, physical examination, and prescriptions. In addition, the Diagnostic Handbook introduced the methods of therapy and aetiology and the use of empiricism, logic and rationality in diagnosis, prognosis and therapy. The text contains a list of medical symptoms and often detailed empirical observations along with logical rules used in combining observed symptoms on the body of a patient with its diagnosis and prognosis.

The symptoms and diseases of a patient were treated through therapeutic means such as bandages, creams and pills. If a patient could not be cured physically, the Babylonian physicians often relied on exorcism to cleanse the patient from any curses. Esagil-kin-apli's Diagnostic Handbook was based on a logical set of axioms and assumptions, including the modern view that through the examination and inspection of the symptoms of a patient, it is possible to determine the patient's disease, its aetiology and future development, and the chances of the patient's recovery.

Esagil-kin-apli discovered a variety of illnesses and diseases and described their symptoms in his Diagnostic Handbook. These include the symptoms for many varieties of epilepsy and related ailments along with their diagnosis and prognosis. Later Babylonian medicine resembles early Greek medicine in many ways. In particular, the early treatises of the Hippocratic Corpus show the influence of late Babylonian medicine in terms of both content and form.

There were libraries and temples in most towns; an old Sumerian proverb averred that "he who would excel in the school of the scribes must rise with the dawn". Women as well as men learned to read and write, and in Semitic times, this involved knowledge of the extinct Sumerian language, and a complicated and extensive syllabary.

A considerable amount of Babylonian literature was translated from Sumerian originals, and the language of religion and law long continued to be written in the old agglutinative language of Sumer. Vocabularies, grammars, and interlinear translations were compiled for the use of students, as well as commentaries on the older texts and explanations of obscure words and phrases. The characters of the syllabary were all arranged and named, and elaborate lists of them were drawn up.

There are many Babylonian literary works whose titles have come down to us. One of the most famous of these was the Epic of Gilgamesh, in twelve books, translated from the original Sumerian by a certain Sin-liqi-unninni, and arranged upon an astronomical principle. Each division contains the story of a single adventure in the career of Gilgamesh. The whole story is a composite product, and it is probable that some of the stories are artificially attached to the central figure.

The brief resurgence of Babylonian culture in the 7th to 6th centuries BC was accompanied by a number of important cultural developments.

Among the sciences, astronomy and astrology still occupied a conspicuous place in Babylonian society. Astronomy was of old standing in Babylonia. The zodiac was a Babylonian invention of great antiquity; and eclipses of the sun and moon could be foretold. There are dozens of cuneiform records of original Mesopotamian eclipse observations.

Babylonian astronomy was the basis for much of what was done in ancient Greek astronomy, in classical, in Sasanian, Byzantine and Syrian astronomy, astronomy in the medieval Islamic world, and in Central Asian and Western European astronomy. Neo-Babylonian astronomy can thus be considered the direct predecessor of much of ancient Greek mathematics and astronomy, which in turn is the historical predecessor of the European (Western) Scientific Revolution.

During the 8th and 7th centuries BC, Babylonian astronomers developed a new approach to astronomy. They began studying philosophy dealing with the ideal nature of the early universe and began employing an internal logic within their predictive planetary systems. This was an important contribution to astronomy and the philosophy of science and some scholars have thus referred to this new approach as the first scientific revolution. This new approach to astronomy was adopted and further developed in Greek and Hellenistic astronomy.

In Seleucid and Parthian times, the astronomical reports were of a thoroughly scientific character; how much earlier their advanced knowledge and methods were developed is uncertain. The Babylonian development of methods for predicting the motions of the planets is considered to be a major episode in the history of astronomy.

The only Babylonian astronomer known to have supported a heliocentric model of planetary motion was Seleucus of Seleucia (b. 190 BC). Seleucus is known from the writings of Plutarch. He supported the heliocentric theory where the Earth rotated around its own axis which in turn revolved around the Sun. According to Plutarch, Seleucus even proved the heliocentric system, but it is not known what arguments he used.

Babylonian mathematical texts are plentiful and well edited. In respect of time they fall in two distinct groups: one from the First Babylonian dynasty period (1830–1531 BC), the other mainly Seleucid from the last three or four centuries BC. In respect of content there is scarcely any difference between the two groups of texts. Thus Babylonian mathematics remained stale in character and content, with very little progress or innovation, for nearly two millennia.

The Babylonian system of mathematics was sexagesimal, or a base 60 numeral system. From this we derive the modern-day usage of 60 seconds in a minute, 60 minutes in an hour, and 360 (60 × 6) degrees in a circle. The Babylonians were able to make great advances in mathematics for two reasons. First, the number 60 has many divisors (2, 3, 4, 5, 6, 10, 12, 15, 20, and 30), making calculations easier. Additionally, unlike the Egyptians and Romans, the Babylonians had a true place-value system, where digits written in the left column represented larger values (much as in our base-ten system: 734 = 7×100 + 3×10 + 4×1). Among the Babylonians' mathematical accomplishments were the determination of the square root of two correctly to seven places (YBC 7289). They also demonstrated knowledge of the Pythagorean theorem well before Pythagoras.

The ner of 600 and the sar of 3600 were formed from the unit of 60, corresponding with a degree of the equator. Tablets of squares and cubes, calculated from 1 to 60, have been found at Senkera, and a people acquainted with the sun-dial, the clepsydra, the lever and the pulley, must have had no mean knowledge of mechanics. A crystal lens, turned on the lathe, was discovered by Austen Henry Layard at Nimrud along with glass vases bearing the name of Sargon; this could explain the excessive minuteness of some of the writing on the Assyrian tablets, and a lens may also have been used in the observation of the heavens.

The Babylonians might have been familiar with the general rules for measuring area. They are also known for the Babylonian mile, which was a measure of distance equal to about 11 kilometres (7 mi) today. This measurement for distances eventually was converted to a time-mile used for measuring the travel of the Sun, therefore, representing time. (Eves, Chapter 2) The Babylonians used also space time graphs to calculate the velocity of Jupiter. This is an idea that is considered highly modern, traced to the 14th century England and France and anticipating integral calculus.

The origins of Babylonian philosophy can be traced back to early Mesopotamian wisdom literature, which embodied certain philosophies of life, particularly ethics, in the forms of dialectic, dialogs, epic poetry, folklore, hymns, lyrics, prose, and proverbs. Babylonian reasoning and rationality developed beyond empirical observation.

It is possible that Babylonian philosophy had an influence on Greek philosophy, particularly Hellenistic philosophy.

Babylonia, and particularly its capital city Babylon, has long held a place in the Abrahamic religions as a symbol of excess and dissolute power. Many references are made to Babylon in the Bible, both literally (historical) and allegorically. The mentions in the Tanakh tend to be historical or prophetic, while New Testament apocalyptic references to the Whore of Babylon are more likely figurative, or cryptic references possibly to pagan Rome, or some other archetype. The legendary Hanging Gardens of Babylon and the Tower of Babel are seen as symbols of luxurious and arrogant power respectively.
