Vahram speaks of the four sons of Tshinggis. The army of the Moguls and of Timur (see his Institutes, p. 229 foll.) was divided into divisions of 10, 100, 1000, &c. The ten followers were the ten first officers or “Comites,” as Tacitus calls the compeers of the German princes. Similar customs are always found in a similar state of society.
