Since before my Ph.D., my research has focused on a largely fifth- and sixth-century cast of characters. For my Ph.D. and subsequent research, I’ve been looking at the following players amongst others: chiefly Pope Leo the Great (of course); Emperors Valentinian III, Theodosius II, and Marcian (but also various predecessors and successors, especially Justinian); other bishops such as (as they come to mind) Hilary of Arles, Cyril of Alexandria, Nestorius of Constantinople, Flavian of Constantinople, Cyril of Alexandria, Severus of Antioch; Leo predecessors in Rome, especially Damasus, Siricius, Innocent I, Zosimus, Celestine I; successors, especially Hilarus, Gelasius I, Vigilius; other secular people such as Empress Pulcheria and Empress Galla Placidia; historical writers such as Prosper of Aquitaine, Hydatius, Marcellinus Comes, Evagrius Scholasticus, Pseudo-Zachariah Rhetor; and monks like John Cassian and Eutyches. These are only a few of the Late Antique people in my research, let alone a medieval cast including Pope Hadrian I, Charlemagne, Lanfranc of Bec, Pope Gregory VII, Gratian, and the moderns from Giovanni Bussi in 1472 to Hubert Wurm in 1939.
Now I’m working on a project involving related manuscripts, but in a very specific context — Durham Cathedral Priory. So a new cast is emerging. The texts transmitted in these manuscripts see many of the old cast — the popes, the councils, St Augustine of Hippo — but the new, High Medieval cast is taking shape for me now.
I am beginning with William of St Calais, after a monastic career in Normandy, he was Bishop of Durham 1080/1-1096. He refounded the religious house here as a Benedictine priory to which he donated at least 49 books, listed here, and some identified in modern locations here. One book not identified in that link is the Decreta Pontificum, now Cambridge, Peterhouse MS 74 — the Collectio Lanfranci.
So Lanfranc here and in the Ph.D. After a monastic career in Normandy, Lanfranc was Archbishop of Canterbury 1070-89. Lanfranc and William were both learned men, and they both used the Collectio Lanfranci in various disputes and claims regarding law and ecclesiastical custom. Of interest is the fact that, when William of St Calais was hauled before the court of King William Rufus (r. 1087-1100) in 1088, Bishop William used Lanfranc’s collection as preparation, but Lanfranc’s denied its validity in what was a secular court over feudal law. More on that once I’ve looked at their manuscripts.
Here we have a king — William Rufus, son of William the Bastard, or Conqueror (r. 1066-1087). My working through a manuscript this week has also brought me into contact with the era of the Conqueror’s other son, King Henry I (r. 1100-35), but those particular documents were largely canon law, about the Investiture Controversy, the Concordat of Worms of 1122 and the First Lateran Council of 1023 — documents by King/Emperor Henry V and Pope Calixtus II.
This I had recently read about in the Historia Regum of Symeon of Durham (d. c. 1130), who also wrote a little book about the history of the church of Durham and possibly even our primary source for Bishop William vs King William Rufus, the De iniusta vexacione, but my research into secondary materials has not got that far yet.
Others, more briefly: Anselm of Canterbury (who did not get along with William of St Calais), Pope Gregory VII, Gratian, Anselm’s biographer Eadmer. It is a new, medieval cast of characters, and some are more than a little colourful. People who use canon law are a varied lot, and we’ll see what I make of their manuscripts.
