G. Zuntz (1902-1992), "Aeschyli Prometheus," Harvard Studies in Classical Philology
95 (1993) 107-111 (at 111):
Every generation of scholars, so it seems, tends to indulge in some
caprice of its own. I have seen the Yeargod come and go, and Myth
and Ritual after him. Now it is the spurious Prometheus; but hardly
much longer. And there is some comfort in the fact that each of these
caprices has led to some improved understanding of its central subject.
Thus the next generation may appreciate Prometheus better than we.
