Thus every creature, and of every kind, The secret joys of sweet coition find. Not only man's imperial race… — Virgil

Thus every creature, and of every kind,

The secret joys of sweet coition find.

Not only man's imperial race, but they

That wing the liquid air, or swim the sea,

Or haunt the desert, rush into the flame:

For love is lord of all, and is in all the same.

In the original (Latin)

Omne adeo genus in terris hominumque ferarumque,

Et genus aequoreum, pecudes, pictaeque volucres,

In furias ignemque ruunt. Amor omnibus idem.
