They are Year-daimones, and the type and model of them all is the old hard-working Helios, the unwearied one… The real true god, the Eniautos-daimon, lives and works for his people; he does more, he dies for them.
Harrison identifies the Eniautos-daimon as the paradigmatic Year God — a functional deity who labours, suffers, and dies for communal fertility, in contrast to the idle Olympian who merely claims honour.
