Collaborative International Dictionary of English v.0.48: Ovolo
\O"vo*lo\, n. [It. ovolo, uovolo, fr. L. ovum an egg. Cf.
Ovule.] (Arch.) A round, convex molding. See Illust. of Column.
[1913 Webster] Note: In Roman work it is usually a quarter
circle in section; in Greek work it is flatter, and is
equivalent to the echinus; that is, it has in section the
elastic curve of the shell of the sea urchin. In mediaeval
architecture it is not distinguishable from the multitude of
convex moldings, of all sections, which are used. [1913 Webster]
