1878.  Browning, La Saisiaz.

        Fretless and free,
  Soul, clap thy pinion!
  Earth have dominion,
Body, o’er thee!

1894.  A. Webster, Mother & Dau. (1895), 17.

        But she is still. A full and crystal lake
  So gives its skies their passage to its deeps
In an unruffled morn where no winds wake,
  And, strong and fretless, stirs not, nor yet sleeps.
