In his excellent study of the Latin and Italian sources of Joachim du Bellay's Antiquitez de Rome, M. Joseph Vianey indicates a number of passages that derive in some way from Lucan's Pharsalia. To the best of my knowledge, no one has pointed out any further borrowings, or made any kind of detailed study of du Bellay's debt to Lucan, which is, however, considerably more extensive than M. Vianey's mentions would lead one to believe. In this paper, therefore, I propose to quote all those passages in the two works which are so similar in expression or in thought as to suggest that du Bellay had Lucan in mind, or actually before him, when he wrote the Antiquitez. After this comparison of details, it will perhaps be possible to show that du Bellay owed to Lucan something much more important than these imitations and translations.
