Going through the pre-Socratics and Aristotle, 

All very—yawn, stretch, glance at the clock. At first

It was the three of them, boy girl boy, good friends

Coming to class, engaged in the discussion whether 

Or not they had done the reading. Three, though odd, 

Is balanced, a teeter-totter, but something is happening, 

A shifting of the fulcrum, a tilt, the balance lost,

Less obscurely—romance! Two of the three pair off—

A Greek drama unfolding in the back row, the chorus 

Facing forward, the singer at the lectern, sweet voiced. 

Now comes Plato, the Apology, Lysis—love burgeons—

The Republic, Symposium—love is—here Phaedrus:

“glorious and blissful is the endeavor of true lovers,”

As for the third of trinity, love as well, of a Platonic nature.
