Which when as Archimago heard, his griefe
2 He knew right well, and him attonce disarmd:
Then searcht his secret wounds, and made a priefe
4 Of euery place, that was with brusing harmd,
Or with the hidden +fire too inly+ warmd.
6 Which done, he balmes and herbes thereto applyde,
And +euermore+ with mighty spels them charmd,
8 That in short space he has them qualifyde,
And him restor'd to health, that would haue algates dyde.
