no fiction wrought magic lore,
But natural was the steed the wizard pressed;
For him a filly to griffin bore;
Hight hippogryph. In wings and beak and crest,
Formed like his sire, as in the feet before;
But like the mare, his dam, in all the rest.
Such on Riphaean hills, though rarely found,
Are bred, beyond the frozen ocean's bound.
And here's how Thomas Bulfinch describes it in 1863:
Like a griffin, he had the head of an eagle, claws armed with talons, and wings covered with feathers, the rest of his body being that of a horse. This strange animal is called a Hippogriff.
