Ancient Mesopotamian units of measurement originated in the loosely organized city-states of Early Dynastic Sumer. Each city, kingdom and trade guild had its own standards until the formation of the Akkadian Empire when Sargon of Akkad issued a common standard. This standard was improved by Naram-Sin, but fell into disuse after the Akkadian Empire dissolved. The standard of Naram-Sin was readopted in the Ur III period by the Nanše Hymn which reduced a plethora of multiple standards to a few agreed upon common groupings. Successors to Sumerian civilization including the Babylonians, Assyrians, and Persians continued to use these groupings. Akkado-Sumerian metrology has been reconstructed by applying statistical methods to compare Sumerian architecture, architectural plans, and issued official standards such as Statue B of Gudea and the bronze cubit of Nippur.
The systems that would later become the classical standard for Mesopotamia were developed in parallel with writing in Sumer during Late Uruk Period (c. 3500–3000). Studies of protocuneiform indicate twelve separate counting systems used in Uruk IV-III. Seven of these were also used in the contemporary Proto-Elamite writing system. [1] The bisexagesimal systems went out of use after the Early Dynastic I/II period. [2]
In Early Dynastic Sumer (c. 2900–2300 BCE) metrology and mathematics were indistinguishable and treated as a single scribal discipline. The idea of an abstract number did not yet exist, thus all quantities were written as metrological symbols and never as numerals followed by a unit symbol. For example there was a symbol for one-sheep and another for one-day but no symbol for one. About 600 of these metrological symbols exist, for this reason archaic Sumerian metrology is complex and not fully understood. [3] In general however, length, volume, and mass are derived from a theoretical standard cube, called 'gur (also spelled kor in some literature)', filled with barley, wheat, water, or oil. However, because of the different specific gravities of these substances combined with dual numerical bases (sexagesimal or decimal), multiple sizes of the gur-cube were used without consensus. The different gur-cubes are related by proportion, based on the water gur-cube, according to four basic coefficients and their cubic roots.[ citation needed ] These coefficients are given as:
One official government standard of measurement of the archaic system was the Cubit of Nippur (2650 BCE). It is a Euboic Mana + 1 Diesis (432 grams).[ citation needed ] This standard is the main reference used by archaeologists to reconstruct the system.
A major improvement came in 2150 BCE during the Akkadian Empire under the reign of Naram-Sin when the competing systems were unified by a single official standard, the royal gur-cube. [4] His reform is considered the first standardized system of measure in Mesopotamia. [4] The royal gur-cube (Cuneiform: LU2.GAL.GUR, 𒈚𒄥; Akkadian: šarru kurru) was a theoretical cuboid of water approximately 6 m × 6 m × 0.5 m from which all other units could be derived. The Neo-Sumerians continued use of the royal gur-cube as indicated by the Letter of Nanse issued in 2000 BCE by Gudea. Use of the same standard continued through the Neo-Babylonian Empire, Neo-Assyrian Empire, and Achaemenid Empire. [3]
Units of length are prefixed by the logogram DU (𒁺) a convention of the archaic period counting system from which it was evolved. Basic length was used in architecture and field division.

The GAN2 system G counting system evolved into area measurements. A special unit measuring brick quantity by area was called the brick-garden (Cuneiform: SIG.SAR 𒊬𒋞; Sumerian: šeg12-sar; Akkadian: libittu-mūšaru) which held 720 bricks.

In the Archaic System time notation was written in the U4 System U. Multiple lunisolar calendars existed; however the civil calendar from the holy city of Nippur (Ur III period) was adopted by Babylon as their civil calendar. [9] The calendar of Nippur dates to 3500 BCE and was itself based on older astronomical knowledge of an uncertain origin. The main astronomical cycles used to construct the calendar were the month, year, and day.

The Classical Mesopotamian system formed the basis for Elamite, Hebrew, Urartian, Hurrian, Hittite, Ugaritic, Phoenician, Babylonian, Assyrian, Persian, Arabic, and Islamic metrologies. [11] The Classical Mesopotamian System also has a proportional relationship, by virtue of standardized commerce, to Bronze Age Harappan and Egyptian metrologies.
The Akkadian Empire was the first known ancient empire of Mesopotamia, succeeding the long-lived civilization of Sumer. Centered on the city of Akkad and its surrounding region, the empire united Akkadian and Sumerian speakers under one rule and exercised significant influence across Mesopotamia, the Levant, and Anatolia, sending military expeditions as far south as Dilmun and Magan in the Arabian Peninsula.
Mesopotamia is a historical region of West Asia situated within the Tigris–Euphrates river system, in the northern part of the Fertile Crescent. Today, Mesopotamia is known as present-day Iraq. In the broader sense, the historical region of Mesopotamia also includes parts of present-day Iran, Turkey, Syria and Kuwait.
Babylonia was an ancient Akkadian-speaking state and cultural area based in the city of Babylon in central-southern Mesopotamia. It emerged as an Akkadian populated but Amorite-ruled state c. 1894 BC. During the reign of Hammurabi and afterwards, Babylonia was retrospectively called "the country of Akkad", a deliberate archaism in reference to the previous glory of the Akkadian Empire. It was often involved in rivalry with the older ethno-linguistically related state of Assyria in the north of Mesopotamia and Elam to the east in Ancient Iran. Babylonia briefly became the major power in the region after Hammurabi created a short-lived empire, succeeding the earlier Akkadian Empire, Third Dynasty of Ur, and Old Assyrian Empire. The Babylonian Empire rapidly fell apart after the death of Hammurabi and reverted to a small kingdom centered around the city of Babylon.
The Kassites were people of the ancient Near East, who controlled Babylonia after the fall of the Old Babylonian Empire c. 1531 BC and until c. 1155 BC.
The cubit is an ancient unit of length based on the distance from the elbow to the tip of the middle finger. It was primarily associated with the Sumerians, Egyptians, and Israelites. The term cubit is found in the Bible regarding Noah's Ark, the Ark of the Covenant, the Tabernacle, and Solomon's Temple. The common cubit was divided into 6 palms × 4 fingers = 24 digits. Royal cubits added a palm for 7 palms × 4 fingers = 28 digits. These lengths typically ranged from 44.4 to 52.92 cm, with an ancient Roman cubit being as long as 120 cm.
Cuneiform is a logo-syllabic writing system that was used to write several languages of the Ancient Near East. The script was in active use from the early Bronze Age until the beginning of the Common Era. Cuneiform scripts are marked by and named for the characteristic wedge-shaped impressions which form their signs. Cuneiform is the earliest known writing system and was originally developed to write the Sumerian language of southern Mesopotamia.
The Babylonian calendar was a lunisolar calendar used in Mesopotamia from around the second millennium BCE until the Seleucid Era, and it was specifically used in Babylon from the Old Babylonian Period until the Seleucid Era. The civil lunisolar calendar was used contemporaneously with an administrative calendar of 360 days, with the latter used only in fiscal or astronomical contexts. The lunisolar calendar descends from an older Sumerian calendar used in the 4th and 3rd millennia BCE.
Assyriology, also known as Cuneiform studies or Ancient Near East studies, is the archaeological, anthropological, historical, and linguistic study of the cultures that used cuneiform writing. The field covers Pre Dynastic Mesopotamia, Sumer, the early Sumero-Akkadian city-states, the Akkadian Empire, Ebla, the Akkadian and Imperial Aramaic speaking states of Assyria, Babylonia and the Sealand Dynasty, the migrant foreign dynasties of southern Mesopotamia, including the Gutians, Amorites, Kassites, Arameans, Suteans and Chaldeans. Assyriology can be included to cover Neolithic pre-Dynastic cultures dating to as far back as 8000 BC, to the Islamic Conquest of the 7th century AD, so the topic is significantly wider than that implied by the root "Assyria".
Naram-Sin, also transcribed Narām-Sîn or Naram-Suen, was a ruler of the Akkadian Empire, who reigned c. 2254–2218 BC, and was the third successor and grandson of King Sargon of Akkad. Under Naram-Sin the empire reached its maximum extent. He was the first Mesopotamian king known to have claimed divinity for himself, taking the title "God of Akkad", and the first to claim the title "King of the Four Quarters". He became the patron city god of Akkade as Enlil was in Nippur. His enduring fame resulted in later rulers, Naram-Sin of Eshnunna and Naram-Sin of Assyria as well as Naram-Sin of Uruk, assuming the name.
Ištaran was a Mesopotamian god who was the tutelary deity of the city of Der, a city-state located east of the Tigris, in the proximity of the borders of Elam. It is known that he was a divine judge, and his position in the Mesopotamian pantheon was most likely high, but much about his character remains uncertain. He was associated with snakes, especially with the snake god Nirah, and it is possible that he could be depicted in a partially or fully serpentine form himself. He is first attested in the Early Dynastic period in royal inscriptions and theophoric names. He appears in sources from the reign of many later dynasties as well. When Der attained independence after the Ur III period, local rulers were considered representatives of Ištaran. In later times, he retained his position in Der, and multiple times his statue was carried away by Assyrians to secure the loyalty of the population of the city.
The of Civilization of Mesopotamia ranges from the earliest human occupation in the Paleolithic period up to Late antiquity. This history is pieced together from evidence retrieved from archaeological excavations and, after the introduction of writing in the late 4th millennium BC, an increasing amount of historical sources. While in the Paleolithic and early Neolithic periods only parts of Upper Mesopotamia were occupied, the southern alluvium was settled during the late Neolithic period. Mesopotamia has been home to many of the oldest major civilizations, entering history from the Early Bronze Age, for which reason it is often called a cradle of civilization.
Number systems have progressed from the use of fingers and tally marks, perhaps more than 40,000 years ago, to the use of sets of glyphs able to represent any conceivable number efficiently. The earliest known unambiguous notations for numbers emerged in Mesopotamia about 5000 or 6000 years ago.
Sargon of Akkad, also known as Sargon the Great, was the first ruler of the Akkadian Empire, known for his conquests of the Sumerian city-states in the 24th to 23rd centuries BC. He is sometimes identified as the first person in recorded history to rule over an empire.
Akkad was the capital of the Akkadian Empire, which was the dominant political force in Mesopotamia during a period of about 150 years in the last third of the 3rd millennium BC.
King of Sumer and Akkad was a royal title in Ancient Mesopotamia combining the titles of "King of Akkad", the ruling title held by the monarchs of the Akkadian Empire with the title of "King of Sumer". The title simultaneously laid a claim on the legacy and glory of the ancient empire that had been founded by Sargon of Akkad and expressed a claim to rule the entirety of lower Mesopotamia. Despite both of the titles "King of Sumer" and "King of Akkad" having been used by the Akkadian kings, the title was not introduced in its combined form until the reign of the Neo-Sumerian king Ur-Nammu, who created it in an effort to unify the southern and northern parts of lower Mesopotamia under his rule. The older Akkadian kings themselves might have been against linking Sumer and Akkad in such a way.
The Sukkalmah Dynasty, also Epartid Dynasty after the founder Eparti/Ebarat, was an early dynasty of West Asia in the ancient region of Elam, to the southeast of Babylonia. It corresponds to the latest part of the Old Elamite period.
Narundi or Narunde was an Elamite goddess worshiped in Susa. She is attested there roughly between 2250 BCE and 1800 BCE. Multiple inscriptions mention her, and it assumed she was a popular deity at the time. In later periods, she occurs exclusively in Mesopotamia, where she played a role in apotropaic rituals in association with the Sebitti. Many attestations are available from late Assyrian sources, but it is not certain if they should be regarded as an indication of continuous worship.
Manzat (Manzât), also spelled Mazzi'at, Manzi'at and Mazzêt, sometimes known by the Sumerian name Tiranna (dTIR.AN.NA) was a Mesopotamian and Elamite goddess representing the rainbow. She was also believed to be responsible for the prosperity of cities.
The proto-cuneiform script was a system of proto-writing that emerged in Mesopotamia, eventually developing into the early cuneiform script used in the region's Early Dynastic I period. It arose from the token-based system that had already been in use across the region in preceding millennia. While it is known definitively that later cuneiform was used to write the Sumerian language, it is still uncertain what the underlying language of proto-cuneiform texts were.
