A Serpent, which mai nevere slepe.
Thus who that evere scholde it winne,
The fyr to stoppe he mot beginne,
Which that the fierce bestes caste,[158]
And daunte he mot hem ate laste,
So that he mai hem yoke and dryve;
And therupon he mot as blyve 3520
The Serpent with such strengthe assaile,
That he mai slen him be bataile;
Of which he mot the teth outdrawe,
