A hinge or pivot. The first figure, in the annexed woodcut, is designed to show the general form of a door, as we find it with a pivot at the top and bottom in ancient remains of stone, marble, wood, and bronze. The second figure represents a bronze hinge in the Egyptian collection of the British Museum: its pivot is exactly cylindrical. Under these is drawn the threshhold of a temple, or other large edifice, with the plan of the folding-doors. The pivots move in holes fitted to receive them, each of which is in an angle behind the antepagmentum. The Greeks and Romans also used hinges exactly like those now in common use. Four Roman hinges of bronze, preserved in the British Museum, are shown in the following woodcut.
