A general principle seldom pointed out which governs the application of enrichments to mouldings in Greek architecture may be cited as a good instance of the subtle yet admirable concord which existed between the different features: it is as follows. _The outline of each enrichment in relief was ordinarily described by the same line as the profile of the moulding to which it was applied._ The egg enrichment (Fig. 91) on the ovolo, the water-leaf on the cyma reversa (Figs. 92 and 97), the honeysuckle on the cyma recta (Fig. 94), and the guilloche (Fig. 100) on the torus, are examples of the application of this rule,--one which obviously tends to produce harmony.
