This was that Philopoemen who was afterwards chief of the Achaeans and a man of the greatest reputation amongst the Greeks, as I have related in his own life. This news coming to Cleomenes, though he had before taken strict care that the city should not be plundered, yet then, being in anger, and out of all patience, he despoiled the place of all the valuables, and sent the statues and pictures to Sparta; and demolishing a great part of the city, he marched away for fear of Antigonus and the Achaeans; but they never stirred, for they were at Aegium, at a council of war. There Aratus mounted the speaker's place, and wept a long while, holding his mantle before his face; and at last, the company being amazed, and commanding him to speak, he said, "Megalopolis is destroyed by Cleomenes." The assembly instantly dissolved, the Achaeans being astounded at the suddenness and greatness of the loss; and Antigonus, intending to send speedy succours, when he found his forces gather very slowly out of their winter-quarters, sent them orders to continue there still; and he himself marched to Argos with a small body of men. And now the second enterprise of Cleomenes, though it had the look of a desperate and frantic adventure, yet in Polybius's opinion, was done with mature deliberation and great foresight. For knowing very well that the Macedonians were dispersed into their winter-quarters, and that Antigonus with his friends and a few mercenaries about him wintered in Argos, upon these considerations he invaded the country of the Argives, hoping to shame Antigonus to a battle upon unequal terms, or else if he did not dare to fight, to bring him into disrepute with the Achaeans. And this accordingly happened. For Cleomenes wasting, plundering, and spoiling the whole country, the Argives, in grief and anger at the loss, gathered in crowds at the king's gates, crying out that he should either fight, or surrender his command to better and braver men. But Antigonus, as became an experienced captain, accounting it rather dishonourable foolishly to hazard his army and quit his security, than merely to be railed at by other people, would not march out against Cleomenes, but stood firm to his convictions. Cleomenes, in the meantime, brought his army up to the very walls, and having without opposition spoiled the country, and insulted over his enemies, drew off again.
A little while after, being informed that Antigonus designed a new advance to Tegea, and thence to invade Laconia, he rapidly took his soldiers, and marching by a side-road, appeared early in the morning before Argos, and wasted the fields about it. The corn he did not cut down, as is usual, with reaping books and knives, but beat it down with great wooden staves made like broadswords, as if, in mere contempt and wanton scorn, while travelling on his way, without any effort or trouble, he spoiled and destroyed their harvest. Yet when his soldiers would have set Cyllabaris, the exercise ground, on fire, he stopped the attempt, as if he felt that the mischief he had done at Megalopolis had been the effort of his passion rather than his wisdom. And when Antigonus, first of all, came hastily back to Argos, and then occupied the mountains and passes with his posts, he professed to disregard and despise it all; and sent heralds to ask for the keys of the temple of Juno, as though he proposed to offer sacrifice there and then return. And with this scornful pleasantry upon Antigonus, having sacrificed to the goddess under the walls of the temple, which was shut, he went to Phlius; and from thence driving out those that garrisoned Oligyrtus, he marched down to Orchomenus.
And these enterprises not only encouraged the citizens, but made him appear to the very enemies to be a man worthy of high command, and capable of great things. For with the strength of one city, not only to fight the power of the Macedonians and all the Peloponnesians, supported by all the royal treasures, not only to preserve Laconia from being spoiled, but to waste the enemy's country, and to take so many and such considerable cities, was an argument of no common skill and genius for command.
