Maybe this is it, but it doesn't sound quite right:
"I have reared a memorial more enduring than brass, and loftier than the regal structure of the pyramids, which neither the corroding shower nor the powerless north wind can destroy; no, not even unending years nor the flight of time itself. I shall not entirely die. The greater part of me shall escape oblivion." [Horace, referring to his own written work]
