Now Zeus the lord of cloud roused in the north a storm against the ships, and driving veils of squall moved down like night on land and sea. The bows went plunging at the gust; sails cracked and lashed out strips in the big wind. We saw death in that fury, dropped the yards, unshipped the oars, and pulled for the nearest lee: then two long days and nights we lay offshore worn out and sick at heart, tasting our grief, until a third Dawn came with ringlets shining. Then we put up our masts, hauled sail, and rested, letting the steersmen and the breeze take over. I might have made it safely home, that time, but as I came round Malea the current took me out to sea, and from the north a fresh gale drove me on, past Cythera. Nine days I drifted on the teeming sea before dangerous high winds. –The Odyssey, Homer What does the sea symbolize in this passage?
