Mytheme in the context of "Symbol"

Roman mythology is the body of myths of ancient Rome as represented in the literature and visual arts of the Romans, and is a form of Roman folklore. "Roman mythology" may also refer to the modern study of these representations, and to the subject matter as represented in the literature and art of other cultures in any period. Roman mythology draws from the mythology of the Italic peoples and shares mythemes with Proto-Indo-European mythology.

The Romans usually treated their traditional narratives as historical, even when these have miraculous or supernatural elements. The stories are often concerned with politics and morality, and how an individual's personal integrity relates to their responsibility to the community or Roman state. Heroism is an important theme. When the stories illuminate Roman religious practices, they are more concerned with ritual, augury, and institutions than with theology or cosmogony.

Christian mythology is the body of myths associated with Christianity. The term encompasses a broad variety of legends and narratives, especially those considered sacred narratives. Mythological themes and elements occur throughout Christian literature, including recurring myths such as ascending a mountain, the axis mundi, myths of combat, descent into the Underworld, accounts of a dying-and-rising god, a flood myth, stories about the founding of a tribe or city, and myths about great heroes (or saints) of the past, paradises, and self-sacrifice.

Various authors have also used it to refer to other mythological and allegorical elements found in the Bible, such as the story of the Leviathan. The term has been applied to myths and legends from the Middle Ages, such as the story of Saint George and the Dragon, the stories of King Arthur and his Knights of the Round Table, and the legends of the Parsival. Multiple commentators have classified John Milton's epic poem Paradise Lost as a work of Christian mythology. The term has also been applied to modern stories revolving around Christian themes and motifs, such as the writings of C. S. Lewis, J. R. R. Tolkien, Madeleine L'Engle, and George MacDonald.

In Greek mythology, Proteus (/ˈproʊtiəs, ˈproʊt.juːs/ PROH-tee-əs, PROHT-yooss; Ancient Greek: Πρωτεύς, romanized: Prōteús) is an early prophetic sea god or god of rivers and oceanic bodies of water, one of several deities whom Homer calls the "Old Man of the Sea" (hálios gérôn). Some who ascribe a specific domain to Proteus call him the god of "elusive sea change", which suggests the changeable nature of the sea or the liquid quality of water. He can foretell the future, but, in a mytheme familiar to several cultures, will change his shape to avoid doing so; he answers only to those who are capable of capturing him. From this feature of Proteus comes the adjective protean, meaning "versatile", "mutable", or "capable of assuming many forms". "Protean" has positive connotations of flexibility, versatility and adaptability.

Mythopoeia (/ˌmɪθəˈpiːə/, Ancient Greek: μυθοποιία, romanized: muthopoiía, lit. 'myth-making'), or mythopoesis, is a subgenre of speculative fiction, and a theme in modern literature and film, where an artificial or fictionalized mythology is created by a writer of prose, poetry, or other literary forms. The concept was widely popularised by J. R. R. Tolkien in the 1930s, although it long predated him. The authors in this genre integrate traditional mythological themes and archetypes into fiction. Mythopoeia is also the act of creating a mythology.

In Greek mythology, Charon or Kharon (/ˈkɛərɒn, -ən/ KAIR-on, -⁠ən; Ancient Greek: Χάρων Ancient Greek pronunciation: [kʰá.rɔːn]) is a psychopomp God, the ferryman of the Greek underworld. He carries the souls of those who have been given funeral rites across the rivers Acheron and Styx, which separate the worlds of the living and the dead. Archaeology confirms that, in some burials, low-value coins known generically as Charon's obols were placed in, on, or near the mouth of the deceased, or next to the cremation urn containing the ashes. This has been taken to confirm that at least some aspects of Charon's mytheme are reflected in some Greek and Roman funeral practices, or else the coins function as a viaticum for the soul's journey. In Virgil's epic poem, Aeneid, the dead who could not pay the fee, and those who had received no funeral rites, had to wander the near shores of the Styx for one hundred years before they were allowed to cross the river. Charon also ferried the living mortals Heracles and Aeneas to the underworld and back again.
