Translations:Mortar and pestle/11/en

Another Stone Age example is the rock mortars in the Raqefet Cave in Israel, which are natural cavities in the cave floors, used by Late Natufians around 10000 BC to grind cereals for brewing beer in the cavities. These rock mortars are large enough for a person to stand upright by them and crush the cereals inside the cavity with a long wooden pestle.
