Plutarch, Cleomenes
Bernadotte Perrin, Ed.

26. A little later, however, hearing that Antigonus had advanced to Tegea with intent to invade Laconia from that city, Cleomenes quickly took his soldiers, marched past the enemy by a different route, and at daybreak appeared suddenly before the city of Argos, ravaging the plain and destroying the grain, not cutting this down, as usual, with sickles and knives, but beating it down with great pieces of wood fashioned like spear-shafts. These his soldiers plied as if in sport, while passing by, and with no effort at all they would crush and ruin all the crop. [2] When, however, they were come to the Cyllarabis and attempted to set the gymnasium on fire, Cleomenes stopped them, feeling that his work at Megalopolis had been done to satisfy his anger rather than his honour.

As for Antigonus, in the first place he went back at once to Argos, and then occupied the hills and all the passes with outposts. But Cleomenes pretended to despise and ignore all this, and sent heralds to the king demanding the keys to the Heraeum, that he might offer sacrifice to the goddess before he went away. [3] Then, after this jest and mockery, and after sacrificing to the goddess under the walls of the temple, which was closed, he led his army off to Phlius. From thence, after expelling the garrison of Oligyrtus, he marched past Orchomenus, not only infusing high spirits and courage into its citizens, but also leading his enemies to think him a man capable of leadership and worthy to wield great power. [4] For he drew his resources from but a single city, and yet waged war against the Macedonian power, all the Peloponnesians, and the treasures of a king together, and not only kept Laconia inviolate, but actually ravaged his enemies' territory and took cities of great size; and men thought this a proof of no ordinary ability and largeness of purpose.
