Agis and Cleomenes

Then he filled up the body of citizens with the most promising of the free provincials, and thus raised a body of four thousand men-at-arms, whom he taught to use a long pike, held in both hands, instead of a short spear, and to carry their shields by a strap instead of by a fixed handle. Next he devoted himself to the training of the young men and to the agoge, or ancient discipline, most of the details of which Sphaerus, who was then in Sparta, helped him in arranging. And quickly was the proper system of bodily training and public messes resumed, a few out of necessity, but most with a willing spirit, subjecting themselves to the old Spartan regime with all its simplicity.

And yet, desiring to give the name of absolute power a less offensive sound, he associated with himself in royal power his brother Eucleidas. And this was the only time when the Spartans had two kings from the same house.

Learning that Aratus and the Achaeans believed that this revolution had jeopardized his position, and therefore did not think that he would venture forth outside of Sparta, or leave the city while it was still in the suspense of so great an agitation, he thought it a fine and helpful thing to make a display of the ready zeal of his army to his enemies.
