A Horatian ode is an ode that repeats the same irregular stanza pattern throughout the poem. It is personal rather than public, general rather than occasional, tranquil rather than intense, and intended for privacy. In a word, good Horatian odes are beautiful.

Gritchka was kind enough to correct my spelling. It is a Horatian ode instead of a HoratiOn ode. Thanks! The definition (a loose one) was taken from my twelvth grade Western Civilization notes. Gritchka also mentioned that the most famous Horatian ode is on Cromwell's return from Ireland.
