When Odysseus's men stumble upon the home of Circe, a goddess, they see wolves and lions all around them. However, these typically vicious animals do not attack them; instead, the animals "fawn" over them, acting somewhat affectionately while they wag their tails. This, right away, strikes his men as very strange. Further, they begin to hear a "sweet voice" emanating from the home, and they realize that it is likely the voice of a goddess. The men, then, decided to call to her. Right away, Circe throws open the doors and invites the men in. Everyone goes inside except Eurylochus, who is suspicious and remains behind. Really, this shows his intelligence. Although all the men were scared of the strange animals' behavior, and though everyone recognized the weirdness of the situation with the animals and the voice from inside, when a stranger simply opened up her doors as though she had been expecting them and invited them all inside, no one could read between the lines to determine that something odd was going on. Only Eurylochus connected all of these odd occurrences and remained skeptical of the stranger's hospitality.
