But on the eastern flank of the kingdom the rich and crowded plains of India invited the conqueror with promises of endless spoils and revenues; while on the west a new continent, full of unknown mysteries, presented virgin fields never yet traversed by the army of an Eastern despot. Darius determined to extend the frontiers of his empire in both these directions.
