Publilius Syrus

Through me you pass into the city of woeThrough me you pass into eternal painThrough me among the people lost for aye.Justice the founder of my fabric movedTo rear me was the task of power divine,Supremest wisdom, and primeval love.Before me things create were none, save thingsEternal, and eternal I shall endure.All hope abandon, ye who enter here.
