opus quadratum : ウィキペディア英語版 | opus quadratum
Opus quadratum is an ancient Roman construction technique, in which squared blocks of stone of the same height were set in parallel courses, most often without the use of mortar. The Latin author Vitruvius describes the technique.〔http://www.vitruvius.be/boek4h4.htm〕 ==Technique== This technique was used by the Romans from about the 6th century BC, and over time the precision and accuracy of the block cutting improved. The technique continued to be used throughout the age of the Roman Empire, even after the introduction of mortar, and was often used in addition to other techniques. The type of stone, the size of the blocks, and the way the blocks were put together can all be used to help archaeologists date structures that display the technique.
