The Rime of the Ancient Professor

 

 

O teach me, teach me, learned man!

The student did implore.

Tell me, quoth she, of PDE

And ODE much more.

 

Since then, each week the selfsame hour,

That agony returns:

And till I have my lecture told,

This heart within me burns.

 

Forthwith this frame of mine was wrenched

With a woeful agony,

Which forced me to begin my class;

And then it left me free.

 

Three times a week I go to class;

I have strange power of speech;

That moment that her face I see,

I know the student must hear me:

To her my class I teach.

 

(EdS, after Coleridge's The Rime of the Ancient Mariner)
