the city, Aratus applied for the city to join the Achaean League, a league of a few small Achaean towns in the Peloponnese. Preferring to use guile rather than military power, Antigonus sought to regain control over Sicyon through winning the young man over to his side. Accordingly, he sent him a gift of 25 talents, but, Aratus, instead of being corrupted by this wealth, immediately gave it away to his fellow citizens. With this money and another sum he received from Ptolemy II Philadelphus, he was able to reconcile the different parties in Sicyon and unite the city. Antigonus was troubled by the rising power and popularity of Aratus. If he were to receive extensive military and financial support from Ptolemy, Aratus would be able to threaten his position. He decided therefore to either win him over to his side or at least discredit him with Ptolemy. In order to do this, he showed him great marks of favour. When he was sacrificing to the gods in Corinth, he sent portions of the meat to Aratus at Sicyon, and complimented Aratus in front of his guests: "I thought this Sicyonian youth was only a lover of liberty and of his fellow-citizens, but now I look upon him as a good judge of the manners and actions of kings. For formerly he despised us, and, placing his hopes further off, admired the Egyptians, hearing much of their elephants, fleets, and palaces. But after seeing all these at a nearer distance, and perceiving them to be but mere stage props and pageantry, he has now come over to us. And for my part I willingly receive him, and, resolving to make great use of him myself, command you to look upon him as a friend." These words were readily believed by many, and when they were reported to Ptolemy, he half believed them. But Aratus was far from becoming a friend of Antigonus, whom he regarded as the oppressor of his city's freedom. In 243 BC, in an attack by night, he seized the Acrocorinth, the strategically important fort by which Antigonus controlled the Isthmus of Corinth and thus the Peloponnese. When news of this success reached Corinth, the Corinthians rose in rebellion, overthrew Antigonus' party, and joined the Achaean League. Next Aratus took the port of Lechaeum and captured 25 of Antigonus's ships. This setback for Antigonus sparked a general
