Eidolons are often described as idealized representations or images of something, particularly in literature and philosophy. They can symbolize the perfect form or essence of an object, concept, or being, reflecting the idea of an archetype. In some contexts, eidolons may also refer to ghostly apparitions or spirits, embodying the notion of a soul or presence that lingers after death. In ancient Greek culture, eidolons were thought to be the shadows or reflections of the deceased, representing their former selves. This concept is closely related to the philosophical ideas of Plato, who discussed forms and ideals, suggesting that the physical world is merely a shadow of a higher reality.
