Munychia
A surname of Artemis, derived from the Attic port-town of Munychia, where she had a temple. Her festival was celebrated at Athens in the month of Munychion. ( Description of Greece by Pausanias Book 1; Strab. xiii. p. 639 ; Eustath. ad Horn. p. 331.)
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom Lives of the Noble Grecians and Romans By Plutarch
When the resolution was taken to begin their attempt with Athens, one of his friends told Antigonus, if they captured Athens, they must keep it safe in their own hands, as by this gangway they might step out from their ships into Greece when they pleased. But Antigonus would not hear of it; he did not want a better or a steadier gangway than people’s good-will; and from Athens, the beacon of the world, the news of their conduct would soon be handed on to all the world’s inhabitants. So Demetrius, with a sum of five thousand talents, and a fleet of two hundred and fifty ships, set sail for Athens, where Demetrius the Phalerian was governing the city for Cassander, with a garrison lodged in the port of Munychia. By good fortune and skillful management he appeared before Piraeus, on the twenty-sixth of Thargelion, before anything had been heard of him. Indeed, when his ships were seen, they were taken for Ptolemy’s, and preparations were commenced for receiving them; till at last, the generals discovering their mistake, hurried down, and all was alarm and confusion, and attempts to push forward preparations to oppose the landing of this hostile force.
