Would to God it were possible for me to see
the work and art of the mighty masters to
come, who are yet unborn, for I know I might
be improved. Ah! How often in my sleep do I
behold great works of art and beautiful things,
the like whereof never appear to me awake,
but so soon as I awake even the remembrance
of them leaveth me.
—Albrecht Dürer, 1512–13
