Nippur in the context of "Uruk"

The Babylonian calendar was a lunisolar calendar used in Mesopotamia from around the 2nd millennium BC until the Seleucid Era (294 BC), and it was specifically used in Babylon from the Old Babylonian Period (1780s BC) until the Seleucid Era.

In the Seleucid Era it was reformed as "Greek time", Anno Graecorum was introduced and used in the Middle East and Egypt until the middle of the first millennium when the First Council of Nicaea AD 325 defined the Church year based on the Roman early Julian calendar. As Anno Graecorum formed the basis for time references in the Bible and spread westward, it rather increased the Babylonian calendars importance. The Babylonian calendar is also partly reflected in calendars in South and East Asia and the Islamic calendar as well as Iranian calendars. The Julian calendar inherited the definitions of the 12 month system, week, hour etc. from the Babylonian calendar and the current Jewish calendar can be seen as a slightly modified Babylonian calendar that still exists today and is practised, but with Anno Mundi Livryat haOlam year calculation since the creation of the world. Today's global time system UTC (Gregorian calendar) therefore has its main structure inherited from the Babylonian calendar.

Ninshubur (𒀭𒎏𒋚,; Ninšubur, "Lady of Subartu" or "Lady of servants"), also spelled Ninšubura, was a Mesopotamian goddess regarded as the sukkal (divine attendant) of the goddess Inanna. While it is agreed that in this context Ninshubur was regarded as female, in other cases the deity was considered male, possibly due to syncretism with other divine messengers, such as Ilabrat. No certain information about her genealogy is present in any known sources, and she was typically regarded as unmarried. As a sukkal, she functioned both as a messenger deity and as an intercessor between other members of the pantheon and human petitioners.

Due to the belief that she could intercede with higher ranking deities, Ninshubur was popular in everyday religion, and many theophoric names invoking her and other references to personal worship are known. Her original cult center was Akkil, but in the Early Dynastic Period she was already worshiped in nearby Uruk. She was also introduced to the pantheon of the state of Lagash, where her cult center was Girsu. Multiple kings of this area regarded her as their personal deity. In the Ur III period she was also introduced to Ur. Further cities where Ninshubur was worshiped include Adab, Nippur, Malgium, and more.

The Early Dynastic Period (abbreviated ED Period or ED) is an archaeological culture in Mesopotamia (modern-day Iraq) that is generally dated to c. 2900 – c. 2350 BC and was preceded by the Uruk and Jemdet Nasr periods. It saw the development of writing and the formation of the first cities and states. The ED itself was characterized by the existence of multiple city-states: small states with a relatively simple structure that developed and solidified over time. This development ultimately led, directly after this period, to broad Mesopotamian unification under the rule of Sargon, the first monarch of the Akkadian Empire. Despite their political fragmentation, the ED city-states shared a relatively homogeneous material culture. Sumerian cities such as Uruk, Ur, Lagash, Umma, and Nippur located in Lower Mesopotamia were very powerful and influential. To the north and west stretched states centered on cities such as Kish, Mari, Nagar, and Ebla.

The study of Central and Lower Mesopotamia has long been given priority over neighboring regions. Archaeological sites in Central and Lower Mesopotamia—notably Girsu but also Eshnunna, Khafajah, Ur, and many others—have been excavated since the 19th century. These excavations have yielded cuneiform texts and many other important artifacts. As a result, this area was better known than neighboring regions, but the excavation and publication of the archives of Ebla have changed this perspective by shedding more light on surrounding areas, such as Upper Mesopotamia, western Syria, and southwestern Iran. These new findings revealed that Lower Mesopotamia shared many socio-cultural developments with neighboring areas and that the entirety of the ancient Near East participated in an exchange network in which material goods and ideas were being circulated.

Ninurta (Sumerian: 𒀭𒊩𒌆𒅁: NIN.URTA, possible meaning "Lord [of] Barley"), also known as Ninĝirsu (Sumerian: 𒀭𒊩𒌆𒄈𒋢: NIN.ĜIR₂.SU, meaning "Lord [of] Girsu"), is an ancient Mesopotamian god associated with farming, healing, hunting, law, scribes, and war who was first worshipped in early Sumer. In the earliest records, he is a god of agriculture and healing, who cures humans of sicknesses and releases them from the power of demons. In later times, as Mesopotamia grew more militarized, he became a warrior deity, though he retained many of his earlier agricultural attributes. He was regarded as the son of the chief god Enlil and his main cult center in Sumer was the Eshumesha temple in Nippur. Ninĝirsu was honored by King Gudea of Lagash (ruled 2144–2124 BC), who rebuilt Ninĝirsu's temple in Lagash. Later, Ninurta became beloved by the Assyrians as a formidable warrior. The Assyrian king Ashurnasirpal II (ruled 883–859 BC) built a massive temple for him at Kalhu, which became his most important cult center from then on.

In the epic poem Lugal-e, Ninurta slays the demon Asag using his talking mace Sharur and uses stones to build the Tigris and Euphrates rivers to make them useful for irrigation. In a poem sometimes referred to as the "Sumerian Georgica", Ninurta provides agricultural advice to farmers. In an Akkadian myth, he was the champion of the gods against the Anzû bird after it stole the Tablet of Destinies from his father Enlil and, in a myth that is alluded to in many works but never fully preserved, he killed a group of warriors known as the "Slain Heroes". His major symbols were a perched bird and a plow.

Enlil, later known as Elil and Ellil, is an ancient Mesopotamian god associated with wind, air, earth, and storms. He is first attested as the chief deity of the Sumerian pantheon, but he was later worshipped by the Akkadians, Babylonians, Assyrians, and Hurrians. Enlil's primary center of worship was the Ekur temple in the city of Nippur, which was believed to have been built by Enlil himself and was regarded as the "mooring-rope" of heaven and earth. He is also sometimes referred to in Sumerian texts as Nunamnir. According to one Sumerian hymn, Enlil himself was so holy that not even the other gods could look upon him. Enlil rose to prominence during the twenty-fourth century BC with the rise of Nippur. His cult fell into decline after Nippur was sacked by the Elamites in 1230 BC and he was eventually supplanted as the chief god of the Mesopotamian pantheon by the Babylonian national god Marduk.

Enlil plays a vital role in the ancient near eastern cosmology; he separates An (heaven) from Ki (earth), thus making the world habitable for humans. In the Sumerian flood myth Eridu Genesis, Enlil rewards Ziusudra with immortality for having survived the flood and, in the Babylonian flood myth, Enlil is the cause of the flood himself, having sent the flood to exterminate the human race, who made too much noise and prevented him from sleeping; the cuneiform tablets of Atra-Hasis report on this connections in a comparatively well-preserved state. The myth of Enlil and Ninlil is about Enlil's serial seduction of the goddess Ninlil in various guises, resulting in the conception of the moon-god Nanna and the Underworld deities Nergal, Ninazu, and Enbilulu. Enlil was regarded as the inventor of the mattock and the patron of agriculture. Enlil also features prominently in several myths involving his son Ninurta, including Anzû and the Tablet of Destinies and Lugale.

Ninsun (also called Ninsumun, cuneiform: 𒀭𒊩𒌆𒄢 NIN.SUMUN_2; Sumerian: Nin-sumun(ak) "lady of the wild cows") was a Mesopotamian goddess. She is best known as the mother of the hero Gilgamesh and wife of deified legendary king Lugalbanda, and appears in this role in most versions of the Epic of Gilgamesh. She was associated with Uruk, where she lives in this composition, but she was also worshiped in other cities of ancient Mesopotamia, such as Nippur and Ur, and her main cult center was the settlement KI.KAL.

The degree of Ninsun's involvement in Gilgamesh's life varies between various versions of the Epic. She only plays an active role in the so-called "Standard Babylonian" version, in which she advises her son and interprets his dreams, petitions the sun god Shamash to protect him, and accepts Enkidu as a member of her family. In the Old Babylonian version her role is passive, with her actions being merely briefly discussed by Shamhat, while a Hittite translation of the text omits her altogether. She is additionally present in older Sumerian compositions, including Gilgamesh and the Bull of Heaven, as well as a poorly preserved and very early myth describing her first meeting with Lugalbanda and their marriage.

A pointed arch, ogival arch, or Gothic arch is an arch with a pointed crown, whose two curving sides meet at a relatively sharp angle at the top of the arch. Also known as a two-centred arch, its form is derived from the intersection of two circles. This architectural element was particularly important in Gothic architecture. The earliest use of a pointed arch dates back to bronze-age Nippur. As a structural feature, it was first used in eastern Christian architecture, Byzantine architecture and Sasanian architecture, but in the 12th century it came into use in France and England as an important structural element, in combination with other elements, such as the rib vault and later the flying buttress. These allowed the construction of cathedrals, palaces and other buildings with dramatically greater height and larger windows which filled them with light.

Shuruppak (Sumerian: 𒋢𒆳𒊒𒆠 Šuruppag, SU.KUR.RU, "the healing place"), modern Tell Fara, was an ancient Sumerian city situated about 55 kilometres (35 mi) south of Nippur and 30 kilometers north of ancient Uruk on the banks of the Euphrates in Iraq's Al-Qādisiyyah Governorate. Shuruppak was dedicated to Ninlil, also called Sud, the goddess of grain and the air. The Early Dynastic IIIa period is also sometimes called the Fara period. Not to be confused with the Levantine archaeological site Tell el-Far'ah (South).

"Shuruppak" is sometimes also the name of a king of the city, legendary survivor of the Flood, and supposed author of the Instructions of Shuruppak".
