impression of the cylinder seal of Ḫašḫamer, patesi (high priest) of
Sin at
Iškun-Sin, ca. 2100 BC. The seated figure is probably
Ur-Nammu, bestowing the governorship on Ḫašḫamer who is led before him by a
lamma. Sin himself is present in the form of a crescent.
'Nanna' (also called ''Suen'') is a
Sumerian god in
Mesopotamian mythology. He is the
god of the moon and the son of
Enlil and
Ninlil. His sacred city was
Ur. The name ''Nanna'' is
Sumerian for "illuminator."
Background
The moon-god is by excellence the god of nomadic peoples, since the moon is their guide and protector at night when they undertake their wanderings. This is just as the sun-god is the chief god of an agricultural people. The cult, once introduced, would tend to persevere, and the development of astrological science culminating in a calendar and in a system of interpretation of the movements and occurrences in the starry heavens would be an important factor in maintaining the position of Sin in the pantheon.
Sin's chief sanctuary at Ur was named ''E-gish-shir-gal'' ("house of the great light.") His sanctuary at Harran was named ''E-khul-khul'' ("house of joys.") On
cylinder seals, he is represented as an old man with a flowing
beard and the crescent as his symbol. In the astral-theological system he is represented by the number 30 and the planet
Venus. 30 probably refers to the average number of days (correctly around 29.53) in a
lunar month, as measured between successive
new moons.
The "wisdom" personified by the moon-god is likewise an expression of the science of
astrology in which the observation of the moon's phases is so important a factor. The tendency to centralize the powers of the universe leads to the establishment of the doctrine of a triad consisting of Sin,
Shamash, and
Ishtar, personifying the
moon, the
sun, and the
earth as the
life-force.
Origin of name
He was named 'Sin' in
Babylonia and
Assyria and was also worshipped in
Harran. Sin had a beard made of
lapis lazuli and he rode on a winged
bull. His wife was
Ningal ("Great Lady") who bore him
Utu ("Sun") and
Inanna, and in some texts,
Ishkur. His symbols are the crescent moon, the bull, and the tripod (which may be a lamp-stand.)
An important Sumerian text ("Enlil and Ninlil")
[1] tells of the descent of Enlil and Ninlil (pregnant with Nanna - Suen) into the underworld. There, three "substitutions" are given to allow the ascent of Nanna - Suen. The story shows some similarities to the text known as "The Descent of Inanna".
Seats of Sin's worship
The two chief seats of Sin's worship were
Ur in the south, and
Harran to the north. The
cult of Sin spread to other centers, and temples of the moon-god are found in all the large cities of Babylonia and Assyria.
He is commonly designated as ''En-zu'', or "lord of wisdom." During the period (c.2600-2400 BC) that Ur exercised a large measure of supremacy over the
Euphrates valley, Sin was naturally regarded as the head of the pantheon. It is to this period that we must trace such designations of Sin as "father of the gods", "chief of the gods", "creator of all things", and the like.
