In poetry:

Humble home. But rum, and charcoal
Grog of sketches on the wall,
And the cell becomes a mansion,
And the garret is a hall.

In that CELL that now moulders away,
And many a brave chief and warrior has bled
Near these walls that now fall to decay.

The girdled Brothers chanting in their stalls,
And see the Prior praying in his cell.

Cells, that were empty fill,
The clay walls shake,
And unimprisoned thought runs where it will.

And left him to feed there all alone

Was heard from those massive walls of stone,
Nor again was the Kalif seen alive!
