The Late Roman Laws on Consanguinity and Affinity and their Patristic BackgroundThis thesis was completed a long time longer than the time of my taking my MA classes at the department of Classics at Dalhousie University. This because of much personal trouble.8 Languages were used in this thesis and a few years of research went into it and many trips to the excellent library at the University of Leiden. Also I had my local library in Gouda track down books and Festschriften from all over the world; for which thanks. The thesis discusses marital laws in the late Roman empire, 4th and 5th centuries; mainly laws concerning the marriage between cousins and a man and his sister-in-law on the wife's side.The everage reader might only find the appendices interesting.
