"There is a silence where hath been no sound,
There is a silence where no sound may be,
In the cold grave, under the deep, deep sea."
and so forth; doubtless you remember the sonnet. Not there, however, is the true silence—
"But in green ruins, in the desolate walls
Of antique palaces, where Man hath been,
Though the dun fox, or wild hyena calls,
And owls, that flit continually between,
Shriek to the echo, and the low winds moan,—
There the true Silence is, self-conscious and alone."
