Quintus Horatius Flaccus (65 BCE–8 BCE), known as Horace, was a Roman lyric poet during the time of Augustus. During the course of Horace's life, Rome transitioned from a republic to an empire. Horace was educated in Rome and in Athens at the Academy. When he was twenty-one, Julius Caesar was assassinated and Horace joined Brutus in the republican cause. He fought with the republican forces at the Battle of Philippi, which ended in defeat for Brutus and his army. A year later, Augustus extenended amnesty to his opponents, and Horace accepted it, eventually becoming part of the emporer's inner circle.
