These stresses also tend to squeeze the blocks outward radially; loads divert these outward forces downward to exert a diagonal force, called thrust, that will cause the arch to collapse if it is not properly buttressed. The bricks are manufactured, matching the exact shape and size of voussoirs, to get very fine workmanship. In ancient Persia, the Achaemenid Empire (550 BC330 BC) built small barrel vaults (essentially a series of arches built together to form a hall) known as iwan, which became massive, monumental structures during the later Parthian Empire (247 BCAD 224).
