Pythian 8.95-97

interpretation of the expression skiās onar ('dream of a shade') as a recapitulation of the earlier words of the dead Amphiaraos about his living son (P.08.043-044): since in Homeric usage the word skiā ('shade') can designate a dead person, the shade of the dead person is literally dreaming - that is, realizing through its dreams – the living person; the occasion of victory in a mortal’s day-to-day lifetime is that singular moment when the dark insubstantiality of an ancestor’s shade is translated, through its dreams, into the shining life-force (aiōn, 097) of the victor in full possession of victory, radiant with the brightness of Zeus (096)
