Alexander the Great was one of the most successful military commanders in history, and was undefeated in battle. By the time of his death, he had conquered most of the world known to the ancient Greeks. ALEXANDER the Great died when he was quite young. He was but thirty-two years of age when he ended his career, and as he was about twenty when he commenced it, it was only for a period of twelve years that he was actually engaged in performing the work of his life. Napoleon was nearly three times as long on the great field of human action. Notwithstanding the briefness of Alexander's career, he ran through, during that short period, a very brilliant series of exploits, which were so bold, so romantic, and which led him into such adventures in scenes of the greatest magnificence and splendor, that all the world looked on with astonishment then, and mankind have continued to read the story since, from age to age, with the greatest interest and attention.
