I am repelled by those who voice the word 'nature', without having any trace of it in their hearts.

-Redon, Odilon
Quoted in Edward Lucie-Smith Symbolist Art (1972).

A picture is finished when all trace of the means used to bring about the end has disappeared.

-Whistler,James (Abbott) McNeill
  The GentleArt of Making Enemies.

Even so for me a vision sanctified The sway of death; long ere my eyes had seen Thy countenanceöthe still rapture of thy mienö When thou, dear Sister! wert become death's bride: No trace of pain or languor could abide That changeöage on thy brow was smoothedöthy cold Wan cheek at once was privileged to unfold A loveliness to living youth denied. Oh! if within me hope should e'er decline, The lamp of faith, lost Friend! too faintly burn; The may that heaven-revealing smile of thine, The bright assurance, visibly return: And let my spirit in that power divine Rejoice, as, through that power, it ceased to mourn.

-Wordsworth,William
