The courteous keeper of the gate: "Come then
Before our steps." We straightway thither came.

The lowest stair was marble white so smooth
And polish'd, that therein my mirror'd form
Distinct I saw. The next of hue more dark

Crack'd lengthwise and across. The third, that lay
Massy above, seem'd porphyry, that flam'd

On this God's angel either foot sustain'd,
Upon the threshold seated, which appear'd
A rock of diamond. Up the trinal steps
My leader cheerily drew me. "Ask," said he,

"With humble heart, that he unbar the bolt."

Piously at his holy feet devolv'd
I cast me, praying him for pity's sake
That he would open to me: but first fell
Thrice on my bosom prostrate. Seven times

Of his drawn sword inscrib'd. And "Look," he cried,
"When enter'd, that thou wash these scars away."
