The main portion of the manuscript Ms. Rh. hist. 27, written in the
early 9th century, contains the so-called Codex of Fraternisation
of Reichenau. Codices of Fraternisation contain a list of the
members of the monastery's confraternities who were required to
include the other living or deceased members of the confraternity
into their daily prayers. The zone of influence was large, reaching
from Reichenau in the South to Monteverde and Conques, from Mondsee
in the East to Fulda and St. Trond in the North as well as to
Jumièges in the West. Over 38.000 names are documented. The
earliest entries have been continuously amended and updated for
several centuries. At the end of the volume, following the Codex of
Fraternisation, there are 15 leaves of parchment from the 10th-12th
centuries containing lists of friars, additional names and
transcriptions of charters. At the beginning of the volume there
are straps glued on paper containing agreements of fraternisation
and obituaries from the 14-16th centuries.
