Mythological king
A mythological king is an archetype in mythology. A king is considered a "mythological king" if he is included and described in the culture's mythology. Unlike a fictional king, aspects of their lives may have been real and legendary, or that the culture (through legend and story telling) believed to be real. In the myth, the legends that surround any historical truth might have evolved into symbols of "kinship" and leadership, and expanded with descriptions of spiritual, supernatural or magical chain of events. For example, in legend the king may have magical weapons and fight dragons or other mythological beasts. His archetypical role is usually to protect and serve the people.
Archetypes of kings
One mythological archetype is the "good king" (McConnel 1979), also sometimes called the "monarchical hero". The "good king" is often the epic hero who made his world safe for civilization. Two examples that scholars have identified as filling the roles and earning the reputation of "good kings" were King Arthur and Beowulf, above and beyond their legendary and historic lives.
