This paper examines the influence of Virgil on Martin Luther, paying special attention to a short verse composition of Luther’s in Latin, Adversus Armatum Virum Cochlaeum, based on the first lines of the Aeneid. The study suggests that an adequate understanding of Luther’s relationship to and use of Virgil needs to take into full account the fact that the Reformer not only knew Virgil’s works and quoted from him frequently, but also himself composed verses based on Virgil’s.
