The geography of Mesopotamia is characterized by diverse environments, including green plains in the northeast, a steppe in the north suitable for animal herding, and a desert in the south where the first cities and writing emerged.
-
The desert region, although arid, could support cities due to the rivers Euphrates and Tigris, which carry loads of silt and fertilize the fields when they flood or deposit water on them.
-
The agriculture of southern Mesopotamia was highly productive, despite insufficient rainfall, due to the use of irrigation canals that were fed by the rivers’ small channels.
-
The use of bronze, an alloy of copper and tin, was essential for the development of cities in Mesopotamia, as it was necessary for creating metal tools, weapons, and other items.
-
The earliest cities in Mesopotamia date back to the Bronze Age, around 3000 BCE, indicating the importance of metal use for city life.
-
The ancient Mesopotamians traded textiles and agricultural produce for mineral resources like wood, copper, tin, silver, gold, shell, and various stones from Turkey, Iran, and across the Gulf.
-
Regulated exchanges for foreign expeditions and goods transport were initiated by the people of southern Mesopotamia, where social organization allowed for crafts, trade, and services.
-
Efficient transportation, particularly over water, is crucial for urban development. River boats or barges were the cheapest mode of transportation, as animals needed to be fed during land transport.
-
Canals and natural channels in ancient Mesopotamia served as routes for goods transport between large and small settlements.
-
The Euphrates was an essential ‘world route’ for the city of Mari and other settlements in ancient Mesopotamia.
-
The first Mesopotamian tablets, dated around 3200 BCE, featured picture-like signs and numbers, used to record transactions involving various goods.
-
Cuneiform, derived from the Latin words ‘cuneus’ and ‘forma’, was used by Mesopotamians to write on clay tablets. This writing system involved pressing wedge-shaped signs onto moist clay, which would then harden in the sun.
-
By 2600 BCE, cuneiform letters replaced the picture-like signs, and the language used was Sumerian. The purpose of writing expanded to include creating dictionaries, legitimizing land transfers, documenting historical events, and announcing legal changes.
-
Sumerian, the earliest known language of Mesopotamia, was gradually replaced by the Akkadian language around 2400 BCE. Cuneiform writing in Akkadian continued to be used for over 2,000 years, until the first century CE.
-
The extensive use of clay tablets for record-keeping has resulted in a wealth of sources, providing extensive knowledge about Mesopotamia, compared to contemporary India.
-
In Mesopotamian society, the nuclear family was the norm, with the father as the head of the family. Marriage procedures involved a declaration, consent from the bride’s parents, a gift from the groom’s people, and exchange of gifts at the wedding.
-
Ur, an early city with narrow, winding streets and no town planning, was systematically excavated in the 1930s. House plots were irregular, and wheeled carts could not reach many houses. Drains and clay pipes were found in inner courtyards.
-
At Ur, household refuse was swept into the streets, causing street levels to rise over time. Light came into rooms from doorways opening into courtyards, providing privacy. Superstitions about houses were recorded in omen tablets.
-
A town cemetery at Ur contained graves of royalty and commoners, with a few individuals buried under the floors of ordinary houses. There were no street drains, and rainwater was channelled into sumps in inner courtyards.
-
Sacks of grain and firewood arrived on donkey-back, as there were no street drains and house roofs sloped inwards, channelling rainwater into sumps in the inner courtyards.
-
The legacy of Mesopotamia includes a scholarly tradition of time reckoning and mathematics.
-
Around 1800 BCE, Mesopotamians had tablets containing multiplication and division tables, square-root tables, and tables of compound interest. The square root of 2 was approximated as 1.41421296.
-
Mesopotamians developed the division of the year into 12 months, the month into four weeks, the day into 24 hours, and the hour into 60 minutes. This system was adopted by successors of Alexander and transmitted to the Roman world, then to the world of Islam, and finally to medieval Europe.
-
Assurbanipal, the last great Assyrian king, collected a library at Nineveh, his capital, containing tablets on history, epics, omen literature, astrology, hymns, and poems. He made efforts to gather old tablets and sent scribes to find them in the south.
-
Nabonidus, the last ruler of independent Babylon, wrote about finding the stele of a very early king and observing the carved image of the Priestess, which helped him dress his daughter for her consecration as Priestess. He also repaired a broken statue inscribed with the name of Sargon, king of Akkad, out of reverence for the gods and respect for kingship.
