2 An armed knight towards them gallop fast,
That seemed from some feared foe to fly,
4 Or other griesly thing, that him +agast+.
Still as he fled, his eye was backward cast,
6 As if his feare still followed him behind;
Als flew his steed, as he his bands had brast,
8 And with his winged heeles did tread the wind,
As he had beene a fole of _Pegasus_ his kind.

As > [As though]
Pegasus his kind > Pegasus's kind (kind = breed. Pegasus is the
winged horse, said to have sprung from the blood of Medusa (see
_Met._ 4.785-6). In later myth, he is regarded as the horse of
the Muses, for it was with a stroke of his hoof that the
inspiring fountain Hippocrene, on Mount Helicon, was caused to
well forth. In the almost incredible fecundity of his vision,
Spenser at this point is surely alive to the image of such a
horse (i.e. art, poetry) serving to carry a man away from
despair)
