KEY WORD : architecture / general terms
Entasis. The bulge in the center of a circular pillar to make it appear straight. In Japan circular pillars called *marubashira 丸柱 had base stones *soseki 礎石 and were placed on a podium *kidan 基壇. They had a bracket system *tokyou 斗きょう on top and were in common use by the 7c-8c. Entasis originated with the ancient Greeks and was a clever device to make their stone columns appear straight. If made straight, they would have appeared to have an inward curve. This method of building was introduced to the Asian continent by the end of the 6c. The use of entasis undoubtedly reached China via the Silk Route through Central Asia, probably during the 3c-4c. The Japanese learned the technique during the late 6c - early 7c when continental building methods were introduced from Korea and China. Some of the original buildings remaining from that early period show entasis in the pillars, for example, Houryuuji *Kondou 法隆寺金堂 in Nara The Kondou was rebuilt in 693. The variations in diameter are easily discernible.
