VIII. As the glory which he won by this action was very great, he and his father Antigonus conceived a strong desire to liberate the whole of Greece from the tyranny of Ptolemy and Kassander. None of the successors of Alexander ever waged a more just or honourable war than this; for Demetrius and Antigonus, to gain themselves honour by freeing the Greeks, spent upon them the treasure which they had won in their victories over the barbarians. They determined first of all to attack Athens, and when one of the friends of Antigonus advised him, if he captured that city, to keep it in his own hands because it was the key of Greece, Antigonus replied that the best key to a country was the goodwill of its people, and that Athens was the watch-tower of the world, from whence the glory of his deeds should shine like a beacon-light to all mankind. Demetrius now set sail for Athens with five thousand talents of silver, and a fleet of two hundred and fifty vessels. At this time Demetrius of Phalerum governed the city as Kassander's lieutenant, and a garrison was placed in Munychia. By good fortune and good management the fleet arrived on the twenty-fifth day of the month Thargelion, without anyone being aware of its coming. When the ships were seen, they were thought to form part of Ptolemy's fleet, and preparations were made to give them a friendly reception. At last the officers in command discovered their mistake, and a scene of great confusion ensued, as they hastily made preparations to resist the enemy, who were already in the act of disembarking; for Demetrius, finding the mouths of the harbours open, sailed straight in, and could be seen distinctly by all standing on the deck of the ship, and making signs to the Athenians to be quiet and keep silence. When this was done, he bade a herald proclaim that his father Antigonus had sent him thither in an auspicious hour to liberate the Athenians, drive out their Macedonian garrison, and restore to them their own laws and ancient constitution.
