 of a triad consisting of Sin/Nanna and his children.

Sin had a beard made of lapis lazuli and rode on a winged bull. The bull was one of his symbols, through his father, Enlil, "Bull of Heaven", along with the crescent and the tripod (which may be a lamp-stand). On cylinder seals, he is represented as an old man with a flowing beard and the crescent symbol. In the astral-theological system he is represented by the number 30 and the moon. This number probably refers to the average number of days (correctly around 29.53) in a lunar month, as measured between successive new moons.

An important Sumerian text ("Enlil and Ninlil") tells of the descent of Enlil and Ninlil, pregnant with Nanna/Sin, into the underworld. There, three "substitutions" are given to allow the ascent of Nanna/Sin. The story shows some similarities to the text known as "The Descent of Inanna".

Nanna's chief sanctuary at Ur was named E-gish-shir-gal, "house of the great light" (cuneiform: 𒂍𒄑𒋓𒃲 e2-giš-šir-gal). It was at Ur that the role of the En-Priestess developed. This was an extremely powerful role held by a princess, most notably Enheduanna, daughter of King Sargon of Akkad, and was the primary cult role associated with the cult of Nanna/Sin.

Sin also had a sanctuary at the city of Harran, named E-hul-hul, "house of joys" (cuneiform: 𒂍𒄾𒄾 e2-ḫul2-ḫul2). The cult of the moon-god spread to other centers, so that temples to him are found in all the large cities of Babylonia and Assyria. A sanctuary for Sin with Syriac inscriptions invoking his name dating to the 2nd and 3rd centuries CE was found at Sumatar Harabesi in the Tektek Mountains, not far from Harran and Edessa.
