Talatat

Talatat are stone blocks of standardized size (ca. 27 by 27 by 54 cm, corresponding to ½ by ½ by 1 ancient Egyptian cubits) used during the reign of Akhenaton in the building of the Aton temples at Karnak and Akhetaten. The standardized size and their small weight made construction more efficient Their use may have begun in the second year of Akhenton's reign. After the Amarna Period talatat construction was abandoned, apparently not having withstood the test of time.
