Under the Sait princes, under the Psemetheks and Nekau, under Apries and Amasis, Egypt was delivered from her enemies and again became mistress of Syria and of the Island of Cyprus. She thus recovered confidence in herself and in her future, and a period ensued which had an art of its own with distinctive features which we shall endeavour to trace. In the intervals of precarious repose which characterized the Persian domination, the Egyptians had leisure neither to invent nor to improve. They copied, as well as they could, the monuments of the twenty-sixth dynasty. Art became a mere collection of technical precepts, kept together and transmitted in the intercourse of the studio, by instruction and practice; it became a mere matter of routine implying, perhaps, great technical skill, but displaying no sincere and personal feeling. Nature was no longer studied or cared for. Artists knew that the human figure should be divided into so many parts. They knew that in the representation of this or that god a certain attitude or attribute was necessary; and they carved the statues required of them after the traditional recipes. Thus Egyptian art became conventional, and so it remained to the end. So it was in the time of Diodorus. The sculptors whom that historian saw at work in Memphis and Thebes, during the reign of Augustus, carved a statue as a modern mechanic would make the different parts of a machine; they worked with a rapidity and an easy decision more characteristic of the precise workman than of the artist.[89] Thought was no longer necessary to them. The due proportions and measurements had been ascertained and fixed many centuries before their time. [89] DIODORUS, i. 98, 7, 8. [Illustration: FIG. 51.--Ouah-ab-ra, 26th dynasty. Louvre. Grey granite, height 37 inches.] But research must still precede discovery. We admit that a day arrived when convention was supreme in Egyptian art, but it could not have begun with convention any more than the arts of other nations. We must here define the terms which we shall have occasion to employ. Every work of art is an interpretation of nature. Let us take the example of the human figure. In the works of a single period and of a single people, it is always full of striking similarity; and yet two original artists never look at it with the same eyes. One will look at it in certain aspects and will bring out certain qualities, which another, although his contemporary and fellow-countryman, will leave in the obscurity of shadows. One will devote himself to the beauty of form, another to the accidents of colour or the expression of passion and thought. The original remains the same, although its interpretations are so various. And these varieties become still more marked when we compare the arts of different races or of different periods--the art of Egypt with that of Assyria or Greece, antique art with that of modern times.
