When he was only twenty he wrote to friends at Sicyon, and finding them of the same mind with himself, he climbed the walls at night and met them.  The people gathered round him, and he caused it to be proclaimed with a loud voice, “Aratus, the son of Clinias, calls on Sicyon to resume her liberty.”  The people all began rushing to the tyrant’s house.  He fled by an underground passage, and his house was set on fire, but not one person on either side was killed or wounded.  Aratus was resolved to keep Sicyon free, and in order to make her strong enough, he persuaded the citizens to join her to the Achaian League; and he soon became the leading man among all the Achaians, and his example made other cities come into the same band of union.  He further tried to gain strength by an alliance with Egypt, and he went thither to see Ptolemy III., called Euergetes, or the Benefactor.  It is said that Ptolemy’s good-will was won by Aratus’ love of art, and especially of pictures.  Apelles, the greatest Grecian painter, was then living, and had taken a portrait of one of the tyrants of Sicyon.  Aratus had destroyed all their likenesses, and he stood a long time looking at this one before he could bring himself to condemn it, but at last he made up his mind that it must not be spared.  Ptolemy liked him so much that he granted him 150 talents for the city, and the Achaians were so much pleased that they twice elected him their general, and the second time he did them a great service.
