Institutio Scripturarum offers you this e-book for free. This
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.
