Symbols are objects, characters, figures, and colors used to represent abstract ideas or concepts.
Although throwing a feast for a guest is a common part of hospitality, hunger and the consumption of food often have negative associations in the Odyssey. They represent lack of discipline or submission to temptation, as when Odysseus tarries in the cave of the Cyclops, when his men slaughter the Sun’s flocks, or when they eat the fruit of the lotus. The suitors, moreover, are constantly eating. Whenever Telemachus and Penelope complain about their uninvited guests, they mention how the suitors slaughter the palace’s livestock. Odysseus kills the suitors just as they are starting their dinner, and Homer graphically describes them falling over tables and spilling their food. In almost all cases, the monsters of the Odyssey owe their monstrosity at least in part to their diets or the way that they eat. Scylla swallows six of Odysseus’s men, one for each head. The Cyclops eats humans, but not sheep apparently, and is gluttonous nonetheless: when he gets drunk, he vomits up wine mixed with pieces of human flesh. The Laestrygonians seem like nice people—until their queen, who is described as “huge as a mountain crag,” tries to eat Odysseus and his men (10.124). In these cases, excessive eating represents not just lack of self-control, but also the total absence of humanity and civility.
The wedding bed in Book 23 symbolizes the constancy of Penelope and Odysseus’s marriage. Only a single maidservant has ever seen the bed, and it is where the happy couple spends its first night in each other’s arms since Odysseus’s departure for Troy twenty years earlier. The symbolism is heightened by the trick that Penelope uses to test Odysseus, which revolves around the immovability of their bed—a metaphor for the unshakable foundation of their love.
