|155 ὁππότε κεν δὴ πάντες ἐλαυνομένην προίδωνται |156 λαοὶ ἀπὸ πτόλιος, θεῖναι λίθον ἐγγύθι γαίης |157 νηὶ θοῇ ἴκελον, ἵνα θαυμάζωσιν ἅπαντες |158 ἄνθρωποι, μέγα δέ σφιν ὄρος πόλει ἀμφικαλύψαι
|155 When all the people of the city look out and see the ship sailing in, |156 turn it into a rock, just as it is about to reach land. |157 Make it look like a swift ship, so that people will look at it with wonder |158 —all of humanity will do so; and make the huge mountain envelop their city.
Before Zeus gives his approval, he modifies the terms of Poseidon's two-part plan for vengeance. In the case of the first part, as we see here, the Will of Zeus is not that the ship be smashed but only that it be turned into a rock at the very moment that it sails into the entrance to the harbor—a rock destined to be a famous landmark for all time to come. In the case of the second part of the sea god’s plan, it seems that Zeus will indeed allow Poseidon to make a huge mountain ‘envelop’ the city. We see here the precise wording of these two parts of the Will of Zeus, addressed as commands to Poseidon.
