Its name, like the names given to the ‘soul’ in many languages, marks it off as something airy and breathlike, revealing its presence in the breathing of the living man. It escapes out of the mouth — or out of the gaping wound of the dying — and now freed from its prison becomes, as the name well expresses it, an ‘image’
Rohde establishes the Homeric psyche as a breath-derived image-soul that becomes an eidolon upon death, foundational to all subsequent discussions of the term.
