Talatat were stone blocks measuring 1⁄2 by 1⁄2 by 1 ancient Egyptian cubits. Their use was initiated under the reign of Akhenaten in the building of the Aten temples at Karnak and Akhetaten (modern Amarna). The standardized size and weight made construction more efficient. Talatat intended for a visible surface were decorated in sunk relief and paint to make up large scenes covering several blocks. They were later reused as fill in the pylons of Horemheb and Ramesses II.
