The passion for building, which we have found so strong in Assyria and Babylonia, possessed, but in a minor degree, a certain number of the Persian monarchs. The simplicity of their worship giving little scope for architectural grandeur in the buildings devoted to religion, they concentrated their main efforts upon the construction of palaces and tombs. The architectural character of these works will be considered in a later chapter. It is sufficient to note here that a good deal of the time and attention of many monarchs were directed to these objects; and particularly it is interesting to remark, that, notwithstanding their worldly greatness, and the flattering voices of their subjects, which were continually bidding them “live for ever,” the Persian kings were quite aware of the frail tenure by which man holds his life, and, while they were still in vigorous health, constructed their own tombs. It was an important principle of the Magian religion that the body should not after death be allowed to mingle with, and so pollute, any one of the four elements. Either from a regard for this superstition, or from the mere instinctive desire to preserve the lifeless clay as long as possible, the Persians entombed their kings in the following way. The body was placed in a golden coffin, which was covered with a close-fitting lid, and deposited either in a massive building erected to serve at once as a tomb and a monument, or in a chamber cut out of some great mass of solid rock, at a considerable elevation above its base. In either case, the entrance into the tomb was carefully closed, after the body had been deposited in it, by a block or blocks of stone. [PLATE XXXVII., Fig. 1.] Inside the tomb were placed, together with the coffin, a number of objects, designed apparently for the king’s use in the other world, as rich cloaks and tunics, trousers, purple robes, collars of gold, earrings of gold, set with gems, daggers, carpets, goblets, and hangings. Generally the tomb was ornamented with sculptures, and sometimes, though rarely, it had an inscription (or inscriptions) upon it, containing the name and titles of the monarch whose remains reposed within. [Illustration: PLATE XXXVII.] If the tomb were a building, and not rock-hewn, the ground in the vicinity was formed into a park or garden, which was planted with all manner of trees. Within the park, at some little distance from the tomb, was a house, which formed the residence of a body of priests, who watched over the safety of the sepulchre.
