The major themes in The Odyssey are especially significant because they serve to form the moral and ethical constitution of most of the characters. The reader learns about the characters through the themes. The more complicated a character is, the more he or she engages these major themes. Therefore, the most complicated character, Odysseus, appropriately embodies each of the themes to one degree or another.
Thinking of hospitality as a major theme in a literary work may seem odd to modern readers. In Homer’s world, however, hospitality is essential. Fagles and Knox (p. 45) refer to hospitality as a dominant part of “the only code of moral conduct that obtains in the insecure world of The Odyssey.”
Arriving strangers may be dangerous or harmless, and residents are wise to be prepared for trouble. Often, however, strangers are but wayfarers, probably in need of at least some kind of help. Similarly, the residents themselves — or their friends or kin — may, at some time, be wayfarers. Civilized people, therefore, make an investment in hospitality to demonstrate their quality as human beings and in hopes that their own people will be treated well when they travel. Furthermore, communications are very primitive in Homer’s world, and strangers bring and receive news. It was through visitors that the Homeric Greeks learned about and kept abreast of what was happening in the world beyond their local areas.
