Aristagoras read the letter, and went to Sparta to try to get the help of the kings in attacking Persia.  He took with him a brass plate, engraven with a map of the world, according to the notions of the time, where it looked quite easy to march to Susa, and win the great Eastern empire.  At first Cleomenes, the most spirited of the kings, was inclined to listen, but when he found that this easy march would take three months he changed his mind, and thought it beyond Spartan powers.  Aristagoras went secretly to his house, and tried to bribe him, at least, to help the Ionians in their rising; but while higher and higher offers were being made, Gorgo, the little daughter of Cleomenes, only eight years old, saw by their looks that something was wrong, and cried out, “Go away, father; this stranger will do you harm.”  Cleomenes took it as the voice of an oracle, and left the stranger to himself.
