Abstract

A typical characteristic of columns in Doric temples is entasis; a slight convexity in the body of a column. Often, and particularly in guide-books, it is suggested that entasis is intended to compensate for an illusion of concavity in columns with truly straight sides. We have investigated whether any such visual illusion exists, both in parallel sided and in tapering columns in a series of experiments, finding little evidence to support any illusion-compensation theory. Further, we explored the possibility that entasis was employed for purely aesthetic reasons, but the results do not support this conclusion. Finally, evidence supporting an engineering role for entasis is presented.

摘要

多立克柱式神庙中柱子的一个典型特征是柱身收分；即柱子柱身有轻微的凸度。通常，尤其是在旅游指南中，有人认为柱身收分旨在补偿柱身侧面真正笔直时所产生的内凹错觉。我们通过一系列实验，对平行边柱和渐缩柱中是否存在这种视觉错觉进行了研究，几乎没有找到支持任何错觉补偿理论的证据。此外，我们探讨了柱身收分纯粹出于美学原因而采用的可能性，但结果并不支持这一结论。最后，本文提出了支持柱身收分具有工程作用的证据。
