    柱子是如何組成?

    一節一節的柱子之間有卡隼,是鐵卡隼,用灌鉛固定在石塊上。

    古希臘的吊桿:

    Ancient Greek cranes

    Greco-Roman Trispastos ("Three-pulley-crane"), the simplest crane type (150 kg load)

    Greco-Roman Pentaspastos ("Five-pulley-crane"), a medium-sized variant (ca. 450 kg load)The crane for lifting heavy loads was invented by the Ancient Greeks in the late 6th century BC. The archaeological record shows that no later than c.515 BC distinctive cuttings for both lifting tongs and lewis irons begin to appear on stone blocks of Greek temples. Since these holes point at the use of a lifting device, and since they are to be found either above the center of gravity of the block, or in pairs equidistant from a point over the center of gravity, they are regarded by archaeologists as the positive evidence required for the existence of the crane.

    The introduction of the winch and pulley hoist soon lead to a widespread replacement of ramps as the main means of vertical motion. For the next two hundred years, Greek building sites witnessed a sharp drop in the weights handled, as the new lifting technique made the use of several smaller stones more practical than of fewer larger ones. In contrast to the archaic period with its tendency to ever-increasing block sizes, Greek temples of the classical age like the Parthenon invariably featured stone blocks weighing less than 15-20 tons. Also, the practice of erecting large monolithic columns was practically abandoned in favour of using several column drums.
