What does eidolon mean?
Eidolon is a literary noun describing an immaterial image of a person or thing: a phantom seen in a dream or vision, or, by extension, an idealized conception of someone. Where a photograph captures what a person looked like, an eidolon captures what they seem to be in the mind's eye — often more beautiful, haunting, or perfect than reality. The word entered English from Greek via Latin in the seventeenth century and has been used by poets and critics ever since, notably by Edgar Allan Poe and W. B. Yeats, for whom eidolons represented elusive ideals. It remains rare and elevated in register, appearing mostly in poetry, philosophy, and literary discussion. To call something an eidolon is to suggest it exists only as an image — glimpsed but never grasped, remembered but no longer real. Its Greek root also gave English the word idol, though an idol is tangible where an eidolon is not.

Etymology of eidolon
Eidolon comes directly from the Greek word 'eidōlon', meaning 'image' or 'phantom', derived from 'eidos' ('form' or 'shape'), itself from the verb 'idein' ('to see'). The same Greek root ultimately produced English words such as 'idol' and 'idea'. The term passed into Latin and entered English usage in the early seventeenth century, retaining its classical sense of a spectral double or idealized image.
How eidolon is actually used
Eidolon is a literary and learned word, rare outside poetry, philosophy, and criticism. It carries connotations of unattainability and unreality; using it signals a deliberately elevated register.
