Nanna is a Sumerian deity, the son of Enlil and Ninlil, and became identified with Semitic Sin.
The two chief seats of Nanna's/Sin's worship were Ur in the south of Mesopotamia and Harran in the north.
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).
Hours: Daily, 10am-4pm Admission: Free Founded in 1494 in what's known as Old Aberdeen, the University and King's College of Aberdeen received its charter from King James IV.
One of the college's identifying features is its huge tower (1633) and an elegant stone dome, the only remaining structure of its kind in Scotland and notable for the stone replica of the imperial crown of Charlemagne that sits atop it.
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".
