Quintus Curtius, a Roman, has described the entrance of the great and victorious Alexander into Babylon, at a later period, who soon after died there of dissipation, while yet a young man. The pleasant sketch gives a vivid impression of the glory and pomp of this ancient capital of Babylon: [Illustration: Christ Declaring Who is Greatest.] "A great part of the inhabitants of Babylon stood on the walls, eager to catch a sight of their new monarch; many went forth to meet him. Among these Bagophanes, keeper of the citadel and of the royal treasure, strewed the entire way before the king with flowers and crowns; silver altars were also placed on both sides of the road, which were loaded not merely with frankincense, but all kinds of odoriferous herbs. He brought with him for Alexander gifts of various kinds, flocks of sheep and horses; lions, also, and panthers were carried before him in their dens. The magi came next, singing in their usual manner their ancient hymns. After them came the Chaldeans with their musical instruments, who are not only the prophets of the Babylonians, but their artists. The first are wont to sing the praises of the kings; the Chaldeans teach the motion of the stars, and the changes of the seasons. Then followed, last of all, the Babylonian knights, whose equipments, as well as that of their horses, showed the passion of the people for luxury. The king, Alexander, attended by armed men, having ordered the crowd of the townspeople to proceed in the rear of his infantry, entered the city in a chariot and repaired to the palace. The next day he carefully surveyed the household treasures of Darius, and all his money. For the rest, the beauty of the city and its age turned the eyes not only of the king, but of everyone in itself, and that with good reason." The kings and conquerors of old had no canals for boats, no railways, and not many good roads. Consequently, their invasions and various public enterprises were carried forward in a slow and toilsome manner. Heavy wagons and chariots, the latter sometimes armed with scythes or long blades for battle, were the best vehicles in use. There were no monitors, nor fire-arms. Large swords, daggers, slings, the catapulta and battering-ram, were the principal weapons. The last named instrument was a massive machine with a movable beam, crowned with a very hard end, often shaped like a ram's head, which could be thrown against a wall with tremendous force, beating it down. The catapulta, which was placed upon city walls, was a great cross-bow for hurling arrows upon an enemy. In it was combined the bow and arrow, and the sling. The mammoth arrow was put in the groove, the twisted ropes were connected with levers, and the powerful recoil would send the strong and sharp arrow a great distance. Some of the machines were large enough to discharge beams loaded with iron; and one kind, called the balista, would send great stones, crushing through the houses on which they fell.
