Horace's "Ars Poetica" is second only to Aristotle's "Poetics" in its influence on literary theory and criticism. Milton recommended both works in his treatise "of Education". Horace's "Satires" and "Epistles" however also had a huge impact, influencing theorists and critics such as John Dryden. There was considerable debate over the value of different lyrical forms for contemporary poets, as represented on one hand by the kind of four-line stanzas made familiar by Horace's Sapphic and Alcaic "Odes" and, on the other, the loosely structured Pindarics associated with the odes of Pindar. Translations occasionally involved scholars in the dilemmas of censorship. Thus Christopher Smart entirely omitted "Odes" 4.10 and re-numbered the remaining odes. He also removed the ending of "Odes" 4.1. Thomas Creech printed "Epodes" 8 and 12 in the original Latin but left out their English translations. Philip Francis left out both the English and Latin for those same two epodes, a gap in the numbering the only indication that something was amiss. French editions of Horace were influential in England and these too were regularly bowdlerized.
