From Wikipedia, the free encyclopedia
CATHETUS1 (Gr. shOros, a perpendicular line), in architecture the eye of the volute2, so termed because its position is determined, in an Ionic or voluted capital, by a line let down from the point in which the volute generates.
In general, a cathetus is a line falling perpendicularly on a surface or another line. A leg of a right triangle (i.e., a side adjacent the right angle) is also known as a cathetus (plural: catheti).
