Wan Imlal

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.
