What is eidolon definition?

Eidolon is a Greek word that means an idealized representation or image of something. In ancient Greek mythology, an eidolon was seen as a ghost or phantom of a deceased person that could haunt the living. In modern usage, the term typically refers to an idealized or perfect image or representation of something, often one that is not actually attainable in reality. An eidolon can be an imaginary creation or a conceptual model that represents something that is abstract or intangible, such as an idealized version of a person, a political ideology, or a philosophical concept. The term is also used in computer science to describe a virtual image or copy of a system or device used for testing or development purposes.
