Unhappy I!——But Fortune stept between:

And proper Physick cur'd me of the Spleen.

And now I'm satisfy'd to keep my Sense:

Make Rules my Guide, to plead in my Defence:

Give to the Roman Sciences their Due:

And write, to whet that Appetite, in you.

Tell what the Duty of a Builder is,

Point out what's Right in Practice; what's amiss.

Shew where, and how to decorate with Skill,

What Ornaments are just, and what are ill.
