The Divine Comedy

NOW came I where the water's din was heard,
As down it fell into the other round,
Resounding like the hum of swarming bees:
When forth together issu'd from a troop,
That pass'd beneath the fierce tormenting storm,
Three spirits, running swift.  They towards us came,
And each one cried aloud, "Oh do thou stay!
Whom by the fashion of thy garb we deem
To be some inmate of our evil land."
