Typical small sandstone building blocks used in Egypt for the temples of Amenophis IV (Akhenaten) at Aten at el-Amarna and Karnak and other temples of the Amarna Period (c 1352-1336 BC). It is the Arabic word for three handbreadths, describing the length of these stones which were used for rapid construction. They are often decorated in relief. After return to orthodox worship of Amen, these monuments were dismantled and their components then used by Akhenaten's successors as rubble hardcore in later buildings.
