[319] Of beauty’s tutors have enrich’d you with?

320 Other slow arts entirely keep the brain;

And therefore, finding barren practisers,

Scarce show a harvest of their heavy toil:

But love, first learned in a lady’s eyes,

Lives not alone immured in the brain;

325 But, with the motion of all elements,

Courses as swift as thought in every power,

And gives to every power a double power,

Above their functions and their offices.
