Sumerian wall plaque showing libation scenes (Ur, c. 2500 BC).
The upper register of this plaque shows a naked priest followed by three worshippers. The priest is pouring a liquid offering from a spouted vessel into a stemmed dish or stand, in front of the figure of a horned god.
In the lower register there are three worshippers. One carries an animal offering, and one is a woman who is shown “full-faced”. She may be a priestess, or she may represent the donor of the plaque. The priest here is pouring a libation in front of an unknown temple.
This plaque was found at Ur, in the ruins of a residence of the high priestess of Nanna (the moon god). It dates from the Early Dynastic Period.
