The third branch of West Asiatic architecture is the Persian, which was developed after Cyrus had conquered the older monarchies, and which attained its greatest magnificence under Darius and Xerxes. The Persians were originally a brave and hardy race inhabiting the mountainous region south of Media, which slopes down to the Persian Gulf. Until the time of Cyrus, who was the founder of the great kingdom of Persia, they inhabited small towns, had no architecture, and were simple barbarians. But after Cyrus had vanquished the wealthy and luxurious Assyrian monarchs, and his warriors had seen and wondered at the opulence and splendour of the Assyrian palaces, it was natural that his successors should strive to emulate for themselves the display of their vassals. Therefore, having no indigenous style to fall back upon, the artisans who were summoned to build the tomb of the founder of the monarchy and the palaces of his successors, simply copied the forms with which they were acquainted. Fortunately, the sites for the new palaces were in a locality where building stone was good and abundant, and the presence of this material had a modifying effect upon the architecture. [Illustration: FIG. 35.--TOMB OF CYRUS.] The best known of the remains which date as far back as the earlier Persian dynasties is the so-called tomb of Cyrus at Pasargadæ, near Murghab (Fig. 35). This may be looked upon as a model in white marble of an old Chaldæan temple, such as the Birs-i-Nimrud. There are the same platforms diminishing in area as the top is approached, and on the topmost platform is a small cella or temple with a gabled stone roof, which probably originally contained the sarcophagus. It is, however, at Persepolis, the real capital of the later Persian kings, whose grandeur and wealth were such that Alexander is said to have found there treasure to the amount of thirty millions of pounds sterling, that we find the most magnificent series of ruins. These were carefully measured and drawn by Baron Texier in 1835, and his work and that of MM. Flandrin and Coste are those from which the best information on this subject can be obtained.
