Thou errest greatly: and, like leech unskilled,
Thou losest heart when smitten with disease,
And know'st not how to find the remedies
Wherewith to heal thine own soul's sicknesses.
Prom. Hearing what yet remains thou'lt wonder more,
What arts and what resources I devised:
And this the chief: if any one fell ill,
There was no help for him, nor healing food,
Nor unguent, nor yet potion; but for want
Of drugs they wasted, till I showed to them
