With the help of king Aeolus, keeper of the winds, Odysseus and his companions sail off from this king’s island, propelled by Zephyros, the West Wind, O.10.025. So, they are traveling from west to east. At O.11.0028–030, we see that they have already sailed for nine days, and then, on the tenth day, Ithaca finally comes into view. But now Odysseus falls asleep at the steering oar, and his companions make the human error of opening the Bag of Winds, so that their ships are blown back, east to west—all the way back to where they started, to the island of Aeolus, O.10.031–055. Aeolus now refuses to help Odysseus and his companions any further, O.056–076, and, as they sail on, O.077–79, it is no longer clear where they are headed. No longer will they be propelled toward Ithaca by the favoring West Wind that Aeolus had provided for them earlier. Their sea voyage is now directionless, and, by the time their ship reaches the land of the Laestrygonians, they have already lost their navigational compass, since this land appears to be a twilight zone, O.080–086. The disorientation will only intensify later, after Odysseus and some of his companions manage to escape from the land of the Laestrygonians and sail to the island of Circe: see the comment on O.10.189–202.
