Hippogriff

To talk of being able to ride with stirrups, is trifling: get on Pegasus, bestride the hippogryph, or mount the white nag in the Revelation.

Je crains done qu'il faudra que nous nous contentions de quelque moyen plus simple et plus facile, comme d'un enchanteur à gages, un hippogriffe, ou au moins de quelque génie bienfaisant, … So I doubt we must be content with some more simple and easy method, such as a magician in our pay, a hippogryph, or at least some kind genius, …

Yet the work is surely not a mere map of the hippogryffon wanderings of some disordered imagination…

I imagine a Hippogryph. The Hippogryph is at once the object of the act and the act itself. Abstract the one, the other has no existence: deny me the consciousness of the Hippogryph, you deny me the consciousness of the imagination; I am conscious of zero; I am not conscious at all.

Oceanus himself follows on a hippogriff, and counsels Prometheus to submit to Zeus.
