The manuscript RN 9/1, which contains the oldest notarial register
in the state archive of Fribourg, is from the chancellery of Pierre
Nonans. It consists of two clearly separated parts. The first 110
leaves contain the ‘normal’ part, which comprises legal matters
between 1 February 1356 (New Style) and 21 March 1359 (New Style).
The second part begins in the opposite direction on folio 123,
ending on folio 110, so that both parts meet on folio 110r. This
second part constitutes a special register (fol. 110-123), which
records the loans arranged between 1 March 1356 (New Style) and 20
March 1359 (New Style) with the Fribourg Lombards, moneylenders
originally from Lombardy but residing in Fribourg since the late
13th century; this register bears the name Registrum Lombardorum.
It is by this name that the entire register has become recorded in
history.
