Famous quotes containing the words external and/or links:

“A tempest cracked on the theatre. Quickly,
The wind beat in the roof and half the walls.
The ruin stood still in an external world.
It had been real. It was something overseas
That I remembered, something that I remembered
Overseas, that stood in an external world.”
—Wallace Stevens (1879–1955)

“Nor stony tower, nor walls of beaten brass,
Nor airless dungeon, nor strong links of iron,
Can be retentive to the strength of spirit.”
—William Shakespeare (1564–1616)
