Lucius Munatius Plancus (born in Tibur, c. 87 BC; died in Gaeta, c. 15 BC) was a Roman senator, consul in 42 BC, and censor in 22 BC with Aemilius Lepidus Paullus. Along with Talleyrand eighteen centuries later, he is one of the classic historical examples of men who have managed to survive very dangerous circumstances by constantly shifting their allegiances.
