Lucius Munatius Plancus (d. c. 20 B.C.) is counted one of the great Roman scoundrels, especially by Velleius Paterculus, who considered him guilty of "fratricide, cowardice, military incompetence, sycophancy, immorality, improbity,... and treachery," according to Andrew Wright. Like another infamous Roman, Clodius Pulcher, Plancus was a contemporary of Julius Caesar. He served under Caesar in the Gallic and Civil Wars and was praetor probably in 47 B.C., consul in 42, and much later, censor in 22. He was proconsul of Gallia Comata, invaded Raetia, and founded the colonies of Lugdunum and (Augusta) Raurica. In the aftermath of the assassination of Julius Caesar, Plancus repeatedly switched sides, put his brother's name on the proscription lists, and finally joined Octavian before Actium. His daughter was the Plancina who was suspected of poisoning Germanicus.
