Antigonus Deson, king of Macedon, had taken possession of the isthmus and citadel of Corinth, which were called the fetters of Greece, because he who was the master of them dominated over that country. Aratus, chief of the Achæans, formed the project of depriving him of this important place; and the following is the manner in which he had the good fortune to succeed. Erginus, an inhabitant of Corinth, having come to Sicyon, formed an intimacy with a well-known banker, a friend of Aratus. In the course of conversation, they happened to speak of the citadel of Corinth, and Erginus said that, going to see his brother Diocles, who was in garrison there, he had remarked, on the steepest side, a little path, cut crosswise in the rock, which led to a place where the wall was very low. The banker asked him, with a laugh, if he and his brother had a mind to make their fortunes? Erginus guessed what he meant, and promised to sound his brother upon the subject. A few days after he returned, and undertook to conduct Aratus to the spot where the wall was not more than fifteen feet high, and, with his brother, to aid him in the rest of the enterprise. Aratus promised to give them sixty thousand crowns if the affair succeeded; but the money must be deposited with the banker, for the security of the two brothers, and as Aratus had it not, and would not borrow it for fear of betraying his secret, the generous Achæan took the greater part of his gold and silver plate, with his wife’s jewels, and placed them in pledge with the banker, for the whole sum. Several accidents delayed this noble enterprise; but nothing daunted the intrepid defenders of liberty. When all was ready, Aratus ordered his troops to pass the night under arms, and taking with him four hundred picked men, the most part of whom were ignorant of what they were going to do, and who carried ladders with them, he led them straight to the gates of the city, by the side of the walls of the Temple of Juno. It was a beautiful moonlight night, which made them justly fear they should be discovered. Fortunately, there arose on the side towards the sea a thick mist, which covered all the environs of the city, and created a complete darkness. There all the troops sat down, and took off their shoes, in order that they might make less noise in marching, and might ascend the ladders better. In the mean time, Aratus, with seven brave, determined young men, equipped as travellers, slipped into the city without being perceived, and in the first place killed the sentinel and the guards on duty. They then applied their ladders to the walls, and Aratus made a hundred of the most resolute ascend with him, desiring the others to follow as best they could. He drew up the ladders, descended into the city, and, at the head of his troops, marched, full of joy, straight towards the citadel, without being perceived. As they advanced, they met a guard of four men, who carried a light. The
