A collection by this author opens with a poem that describes a miser being cut in half with an axe by a freedwoman and begins by asking why "no one alive's ever content with his lot". Another of his works tells the addressee to put a manuscript "in the closet for nine years" since "one can always destroy what one hasn't published". This man advocated the golden mean in a poem that begins (*) "Rectius vives, Licini" and claimed to have "made a monument more lasting than bronze" in another poem. He criticized purple prose in a letter to Lucius Calpurnius Piso that coined the phrases "even good Homer nods", "ut pictura poesis", and "in medias res". For 10 points, name this Roman author of Ars Poetica whose four books of Odes contain such other memorable phrases as "dulce et decorum est pro patria mori" and "carpe diem".
