shaft; and the bulbous root, the pedestal. The blue vault of the sky
undoubtedly suggested the dome, etc.

The following are a few of the leading principles of ornamental art as set
forth by Owen Jones in his _Grammar of Ornament_, a fine work,
magnificently illustrated, whose perusal could hardly fail to delight the
most indifferent:

"All good ornamental art should possess fitness, proportion, harmony, the
result of all which is repose."

"Construction should be decorated. Decoration should never be purposely
constructed."

"All ornament should be based upon geometrical construction."

"Harmony of form consists in the proper balancing and contrast of the
straight, the inclined, and the curved."

"In surface decoration all lines should flow out of a parent stem. Every
part, however distant, should be traced to its branch or root. Natural
law."

"All junctions of curved lines with each other, or with straight lines,
should be tangential to each other. Natural law."

"Natural forms, as subjects of ornament, should not be imitated, but should
be conventionalized."
