The struggle between them is that between right and wrong, and in it every man must take one or the other side. His soul will survive what men call death, and receive an everlasting reward according to his deeds. After quitting the mortal body, the soul will pass over the Bridge of Judgment, and will there be turned aside to the right or to the left; if it has been virtuous, to enter Paradise, but if vicious, the House of Falsehood. Full of this doctrine, Zarathustra enters the court of King Vishtāspa, and converts him and his court. The monarch in turn sets out to convert the unbelieving world by the sword, and the War of Religion begins. [Sidenote: Spread of Persism.] =9.= We cannot trace the long history of the War of Religion through its whole course, but in the end we find that the Religion has welded together the great kingdom of Persia, and its warlike zeal is directed towards establishing throughout the world the worship of the ‘God of heaven,’ and the destruction of all images, whether in the shape of men or of beasts, as dishonouring to the divine nature. In the sixth century B.C. Babylon opposed the Religion in the east, and Lydia in the west; both fell before Cyrus the Great. The fall of Babylon set free the Jews, who accepted the king’s commission to establish the Religion in Jerusalem[24], and (at a rather later date) in Egypt[25]; on the other hand that of Lydia exposed the Hellenes, a people devoted to idol-worship, to the fury of the image-breakers[26]. The battles of Marathon and Salamis checked the warlike advance of Persism, and the victories of Alexander suppressed its outward observance and destroyed its literature and its priesthood. But in this period of apparent depression some at least of its doctrines were winning still wider acceptance than before. [Sidenote: Persism invades Greece.]
