Some of the terms are derived thus: Fillet, from the French word fil, thread. Astragal, from astragalos, a bone of the heel - or the curvature of the heel. Bead, because this moulding, when properly carved, resembles a string of beads. Torus, or tore, the Greek for rope, which it resembles when on the base of a column. Scotia, from skotia, darkness, because of the strong shadow which its depth produces, and which is increased by the projection of the torus above it. Ovolo, from ovum, an egg, which this member resembles, when carved, as in the Ionic capital. Cavetto, from cavus, hollow. Cymatium, from kumaton, a wave.
