THERE were three great European nations in ancient days, each of which furnished history with a hero: the Greeks, the Carthaginians, and the Romans. Alexander was the hero of the Greeks. He was King of Macedon, a country lying north of Greece proper. He headed an army of his countrymen, and made an excursion for conquest and glory into Asia. He made himself master of all that quarter of the globe, and reigned over it in Babylon, till he brought himself to an early grave by the excesses into which his boundless prosperity allured him. His fame rests on his triumphant success in building up for himself so vast an empire, and the admiration which his career has always excited among mankind is heightened by the consideration of his youth, and of the noble and generous impulses which strongly marked his character. The ROMAN hero was CAESAR. He was born just one hundred years before the Christian era. His renown does not depend, like that of Alexander, on foreign conquests, nor, like that of Hannibal, on the terrible energy of his aggressions upon foreign foes, but upon his protracted and dreadful contests with, and ultimate triumphs over, his rivals and competitors at home.
