Cuneiform
Cuneiform was the system of writing used most extensively in the ancient Middle East. Cuneiform was employed for writing a number of languages from about the end of the 4th millennium BC until about the 1st century BC.

The
earliest attested documents in cuneiform were written in Sumerian, the language
of the inhabitants of southern Mesopotamia and Chaldea from the 4th until the
2nd millennium BC. Discovered at the site of the ancient city of Uruk (biblical
Erech), they were in a pictographic type of cuneiform in which objects were
represented by pictures, numbers were represented by the repetitional use of
strokes or circles, and proper names were indicated by combinations of pictures
used according to the rebus principle; i.e., the pictures were to be interpreted
according to their usual pronunciations rather than according to the objects
they depicted.
About
the 3rd millennium BCE, the pictographs gradually began to change to conventionalized linear
drawings and because they were pressed into soft clay tablets with the slanted
edge of a stylus, came to have a wedge-shaped appearance. Earlier cuneiform was
written in columns from top to bottom but during the 3rd millennium came to be
written from left to right with the cuneiform signs turned on their sides. At
about the same time these changes in the cuneiform writing system were
occurring, it was adopted by the Akkadians, Semitic invaders of Mesopotamia, for
writing their language. The earliest Akkadian cuneiform inscriptions date from
the Old Akkadian or Early Akkadian period (c. 2450 to c. 1850 BC), during which
the inscriptions of Sargon, the great ruler of Akkad, were written. Cuneiform
continued to be used for writing the Assyrian and Babylonian dialects descended
from Akkadian.
Cuneiform
was borrowed by the Elamites, the Kassites, the Persians, the Mitanni, and the
Hurrians. The Hurrians passed the cuneiform writing system on to the Hittites,
who spoke an Indo-European language; cuneiform was also used for the languages
(e.g., Luwian, Hattian) spoken in areas under Hittite control.
