This manuscript from the library of Walter Supersaxo (ca.
1402-1482), Bishop of Sion, and of his son Georg (ca. 1450-1529),
with initials in red and blue (some with pen-flourish initials,
e.g. on ff. 1r and 113v; two drawings on ff. 77r and 91r), contains
eight legal treatises in Latin, half of them anonymous: 1. Johannes
de Blanasco, (Libellus super titulo) de actionibus (ff. 1r-45r); 2.
Aegidius de Fuscarariis, Ordo judiciarius (ff. 46r-67v); 3. Ordo
judiciarius “De edendo“ (ff. 68r-69v; incomplete); 4. Ordo
judiciarius “Scientiam“ (ff. 69v-75v); 5. Tancred of Bologna,
Ordo judiciarius (ff. 77r-113v); 6. Contentio actoris et rei (ff.
113v-117r); 7. Parvus ordo judiciarius (ff. 117r-121v); 8. [Tancred
of Bologna / Raymond of Penyafort], Summa de matrimonio (ff.
121v-125v; incomplete). Johannes de Blanosco († ca. 1281 or
later) from Burgundy studied and probably also taught law in
Bologna before returning home and placing himself in the service of
Duke Hugo IV of Burgundy. In 1256, perhaps when he was still in
Bologna, he wrote his commentary on the Institutes “De
actionibus“. The author of the second treatise in this
manuscript, Aegidius de Fuscarariis (†1289), was the first lay
teacher for canon law at the University of Bologna. His Ordo
judiciarius from 1263-1266 is his most important work. Tancred of
Bologna (ca. 1185-ca. 1236), the author of texts 5 and 8, was a
renowned canonist and archdeacon, who associated with Popes
Innocent III, Honorius III and Gregory IX; among his works, the
Summa de sponsalibus et matrimonio, written around 1210-1214 and
revised by Raymond of Penyafort in 1235, enjoyed some success. But
he became famous through his Ordo judiciarius (ca. 1214-1216),
which established itself throughout Europe as the reference work
for legal procedure. Regarding the four anonymous (or not-securely
attributed) treatises of manuscript S 102: number 3, better known
by the title Ulpianus de edendo, was probably created in England in
1140-1170; number 4 prior to 1234 in France (its author is a
certain Gualterus, perhaps identical to Gauthier Cornu, Archbishop
of Sens); number 6, from the time of the papacy of Gregory IX, may
be of Anglo-Norman origin; and finally number 7, which was written
in the North of France in two versions in 1221 and 1238. The
Supersaxo library contains numerous legal works. S 102 can best be
compared with manuscript S 104 (Goffredus Tranensis, Summa super
titulis Decretalium), which likewise is a 14th century work from
Bologna.
