Narses superseded Belisarius in the command of the armies of Italy, by the orders of the Emperor Justinian. He defeated Totila, the king of the Goths (who had taken Rome), in a decisive engagement, in which the latter was slain. He governed Italy with consummate ability for thirteen years, when he was ungratefully recalled by Justin the Second, the successor of Justinian.

Tamerlane, or Timour, was a native of Samarcand, of which territory he was elected emperor. He overran Persia, Georgia, Hindostan, and captured Bajazet, the valiant Sultan of the Turks, at the battle of Angora, 1402, whom he is said to have inclosed in a cage of iron. His conquests extended from the Irtish and Volga to the Persian Gulf, and from the Ganges to the Grecian Archipelago. While preparing for the invasion of China, he died, in the 70th year of his age, A. D. 1405. He was tall and corpulent in person, but was maimed in one hand, and lame on the right side.
