anxious to have good relations with Epirus' powerful neighbour, as was sanctioned by the marriage between the regent's daughter Phthia and Antigonus' son and heir Demetrius. Chremonidean War With the restoration of the territories captured by Pyrrhus, and with grateful allies in Sparta and Argos, and garrisons in Corinth and other cities, Antigonus securely controlled Macedonia and Greece. The careful way he guarded his power shows that he wished to avoid the vicissitudes of fortune that had characterized the careers of his father and grandfather. Aware that the Greeks loved freedom and autonomy, he was careful to grant a semblance of this in as much as it did not clash with his own power. Also, he tried to avoid the odium that direct rule brings by controlling the Greeks through intermediaries. It is for this reason that Polybius says, "No man ever set up more absolute rulers in Greece than Antigonus." The tyrants installed or maintained by Gonatas include: Cleon (Sicyon, c. 300–280 BC), Euthydemus and Timocleidas (Sicyon c. 280–270 BC), Iseas (Keryneia, resigned 275 BC), Aristotimus (Elis, assassinated 272 BC), Aristippus the Elder (Argos, from 272 BC), Abantidas (Sicyon, 264–252 BC), Aristodemus the Good (Megalopolis, assassinated 252 BC), Paseas (Sicyon, 252–251 BC), Nicocles (Sicyon, 251 BC), Aristomachus (Argos, assassinated 240 BC), Lydiadas, (Megalopolis, c. 245–235 BC), and Aristippus (Argos, 240–235 BC). The next stage of Antigonus's career is not documented and what we know has been patched together from a few historical fragments: Antigonus seems to have been on very good terms with Antiochus, the Seleucid ruler of Asia, whose love for Stratonice, the sister of Antigonus, is very famous. Such an alliance naturally threatened the third successor state, Ptolemaic Egypt. In Greece, Athens and Sparta, once the dominant states, naturally resented the domination of Antigonus. The pride, which in the past had made these cities mortal enemies, now served to unite them. In 267 BC, probably with encouragement from Egypt, an Athenian by the name of Chremonides persuaded the Athenians to join the Spartans in declaring war on Antigonus (see Chremonidean War). The Macedonian king responded by ravaging the territory of Athens with an army while blockading them by sea. In this campaign he also destroyed the grove and temple of Poseidon that stood at the entrance to Attica near the border with Megara. To support the Athenians and prevent the power of Antigonus from growing too much,
