The Course of Honour is a historical novel by Lindsey Davis, set in ancient Rome and concerning the emperor Vespasian and his lover Caenis. It was the first novel Davis wrote which was set in ancient Rome, but was not published until 1997 after she had become known for the Falco series. Davis has said "I see it as my first real book, and because the true story is so wonderful, it will always be my favourite."
