Classic Poem

Satirical Verses, I think, 'tis you ask—
I'm frighten'd to think of so arduous a task!
Before this decree I submissively follow,
You must give me the genius and wit of Apollo:
Yourself too, the subject?—why then I've to mention,
You must give me a wonderful stock of invention;
It were not sufficient my lines were harmonious,
Whilst all wou'd agree that the choice was erroneous.
You must give me a proof, (to extinguish all praise)
That Sense and Good-humour are banished from H——s.
In short—these said verses—I ne'er can indite them,
Unless you can give me some reason to write them.
