There are many elements associated with Greek mythology, but the Greek gods and heroes may be one of the most distinctive elements of this type of cultural lore. In addition to the characters, Greek mythology often involves clever tales that teach lessons, explain rituals or natural phenomena, and even tell the history of ancient Greece. Specific elements in these stories are not always the same in all versions, but the overall message of the story is typically consistent. One of the most common themes in Greek myths involves the problems that arise when gods and men interact or when men disobey the gods.
Greek mythology is typically characterized by a large number of well-defined gods and heroes whose tales have been told repeatedly, giving each character a unique and complex history. For example, Zeus, who is the king of the gods, is involved in many different myths to varying degrees. Heroes, much like gods, often appear in multiple tales. This predictable cast of characters is one of the defining elements of Greek mythology. Many tales concern the genealogy of the characters, their relationships, and their problems.
The setting for most Greek myths is in ancient Greece, although some myths are set in the underworld, Mount Olympus, and other purely mythical areas. Even when these stories were told, most of the tales were set in the past. The line between history, religion, and myth was much more blurred in ancient Greece than it is in most current societies, and so many elements of these stories were possibly taken to be literal facts about the past. The historical focus of these myths and the epic scale they sometimes reach is a distinctive element of these stories.
Magic and prophecy are also major themes in Greek mythology. Fate, for example, is often a major tripping point for the protagonist in a Greek myth. When characters disobey the gods or persist in actions they have been told to avoid, consequences are almost always unavoidable. Rituals often play a major role in Greek myths, as sacrifices can often appease the gods.
In terms of storytelling, there are many different ways in which Greek myths can be presented. The myths themselves typically have a coherent beginning, middle, and end, although some appear to depend on knowledge of other elements of the mythology. As these tales were originally transmitted orally, they were sometimes told entirely in verse. Given the diverse storytellers, many different versions of these myths exist, sometimes including characters with different names or slightly different plots.
