A paintings of a round head woman.
Holes in stone of varying sizes. These holes are called "Kettles" and the smaller holes next to them are "cups".
According to Fabrizio Mori, a large number of these kettles are found in or very
near shelters with Round Head Paintings, and that they certainly date to before
the 8th millennium BP. No organic remains have ever been found in any of these
holes except in one from Wadi T-anshalt in Tashwinat, which contained traces
of calcium phosphate, and thus excludes the possibility of them being used for
grinding food even farther. He concludes that although they may have something
to do with water, it is more likely that they were used for ritual purposes.
