A well-known manuscript in the Prague National Museum contains the text
published in this volume. The author was a student of Roffredus
Beneventanus. He composed an apparatus of glossae recollectae and
concealed his name behind a siglum consisting of three points in the
shape of triangle. He used the first person in only a few instances. The
work preserves important parts of Roffredus' lecturae held in Naples
between ca. 1220 and 1230 and later for a few years in a school in the
Roman Curia that is not well known. The work demonstrates that, among
the civil law glossators of the 13th century, Roffredus was among the
first ones to use the ius canonicum extensively. It also provides us
with information about the final period of Roffredus' life.
