The satirical poet Lucilius was a senator's son who could castigate his peers with impunity. Horace was a mere freedman's son who had to tread carefully. Lucilius was a rugged patriot and a significant voice in Roman self-awareness, endearing himself to his countrymen by his blunt frankness and explicit politics. His work expressed genuine freedom or libertas. His style included 'metrical vandalism' and looseness of structure. Horace instead adopted an oblique and ironic style of satire, ridiculing stock characters and anonymous targets. His libertas was the private freedom of a philosophical outlook, not a political or social privilege. His "Satires" are relatively easy-going in their use of meter (relative to the tight lyric meters of the "Odes") but formal and highly controlled relative to the poems of Lucilius, whom Horace mocked for his sloppy standards ("Satires" 1.10.56–61)
