But the sacred dance is by no means confined to the discharge of physical energy under the promptings of joy. The funeral dance is one of the most frequent of such observances, and dread of divine wrath and the hope of propitiation by means of rites pleasing to the offended power form a frequent occasion for rhythmic evolution and violent bodily demonstration. Far more commonly, however, does the sacred dance assume a representative character and become a rudimentary drama, either imitative or emblematic. It depicts the doings of the gods, often under the supposition that the divinities are aided by the sympathetic efforts of their devotees. Certain mysteries, known only to the initiated, are symbolized in bodily movement. The fact that the dance was symbolic and instructive, like the sacrificial rite itself, enables us to understand why dancing should have held such prominence in the worship of nations so grave and intelligent as the Egyptians, Hebrews, and Greeks. Representations of religious processions and dances are found upon the monuments of Egypt and Assyria. The Egyptian peasant, when gathering his harvest, sacrificed the first fruits, and danced to testify his thankfulness to the gods. The priests represented in their dances the course of the stars and scenes from the histories of Osiris and Isis. The dance of the Israelites in the desert around the golden calf was probably a reproduction of features of the Egyptian Apis worship. The myths of many ancient nations represent the gods as dancing, and supposed imitations of such august examples had a place in the ceremonies devoted to their honor. The dance was always an index of the higher or lower nature of the religious conceptions which fostered it. Among the purer and more elevated worships it was full of grace and dignity. In the sensuous cults of Phoenicia and Lydia, and among the later Greek votaries of Cybele and Dionysus, the dance reflected the fears and passions that issued in bloody, obscene, and frenzied rites, and degenerated into almost incredible spectacles of wantonness and riot.
