'In 'Ars Poetica', written around 19 BCE, Horace postulated 'ut pictura poesis'. This formulation, abbreviated by scholars as u.p.p., has been chewed over in the intervening two millennia. Horace's dictum translates to 'as is painting so is poetry'. U.p.p. was a restatement of the claim by Simonides of Ceos that 'poema pictura loquens, pictura poema silens' (poetry is a speaking picture, painting a silent poetry), but with the order of artforms reversed.'
