The origin of all attempts at decorating or beautifying objects lies in the universal love of mankind for the beautiful. Once the necessaries of life provided for, man instinctively, the world over, turns his attention toward gratifying this feeling, by improving and decorating the forms around him--his arms, utensils, dwelling, or his own person. The history of every nation proves this, and no matter how rude, and even ugly, their efforts may seem to us, we are bound to recognize in them the same motives that actuated the builders of the Parthenon or of St. Peter's at Rome. This awakening and gratification of the æsthetic sense seems to be the first advance from a condition of mere animal existence, in which food, shelter, and comfort are the only considerations, to tastes and desires that are higher and, consequently, more impersonal. The term historic ornament is applied to the various styles of ornamental art which have flourished at various periods in the world's history, from the Egyptian, dating from the 14th century B.C., to those that exist at the present day. Their number is, consequently, almost unlimited, and we will confine ourselves to the consideration of a few of the principal ones only--those that have achieved the most enduring fame, or those that exercised the most marked influence upon succeeding styles. In considering the various styles, we must always bear in mind that, with the exception of the Egyptian, all show very markedly the influence of the styles that preceded them, being very often merely an outgrowth or development of a preceding one. Thus the Greeks borrowed many forms from the Egyptians. The Romans simply adapted and elaborated the Greek style, etc. So that while each style is usually known by certain prominent characteristics, it does not follow that these characteristics are peculiar to it alone.[1] They may be found in other styles, though not to such a great extent. While similar features will thus be seen to run through many styles, each will usually be found to possess an individuality of its own. Every nation, like every individual, possesses different wants and capabilities, and will develop itself accordingly. Differences in religion, climate, manners, customs, etc., will cause differences in their art and literature, the most lasting monuments of their morals, taste, and feelings.
