Relational Analysis, Part 1

Overview

This is a network map of all of Foigny’s friendship groups, color-coded based on sub-network. As you can see, most of the networks are centralized, that is, they are centered around a specific individual, or, in the case of one network, two individuals. This network covers the entirety of the timespan covered by the charter, 1121-1300, and not a snapshot in time.

Essentialized Network

This is the same network map as above, but with each of the sub-networks condensed into a single node. This view allows us to see the relationship between various groups. The numbers assigned to each group have no particular significance – they are auto-generated by Gephi. The central person of each network is:

  • 4 – A collection of anonymous canons of Laon, appearing in the cartulary from 1224-1278.
  • 11 – Clement of St-Germain, canon of Laon, appearing from 1240-1244.
  • 18 – Gautier de Mortagne, bishop of Laon, appearing from 1151-1178.
  • 33 – Albéric de Humbert, archbishop of Reims, appearing from 1211-1219.
  • 38 – Jobert, Lord of Vénéroles and Mt-St-Hubert, appearing in 1227 only.
  • 40 – Anselm de Mauny or de Bercenay, bishop of Laon, appearing from 1218-1235.
  • 45 – Pierre II, lord of Fussigny, appearing from 1253-1262.
  • 48 – William de Antogniaco, canon of Laon, appearing in 1240 only.
  • 50 – Raoul de Buirefontaine, appearing in 1187 only.
  • 55 – Jean I de Châtillon, Count of Blois and Lord of Guise and Avesnes, appearing in 1260 only.
  • 56 – Raoul, lord of Marle, appearing in 1249 only, and Enguerrand IV, lord of Coucy, from 1266-1296.
  • 57 – Jean de Busancy, canon of Laon and Meaux, appearing from 1216-1228.
  • 62 – Marie Pain-et-Lait, citizen of St-Quentin, appearing in 1237 only. This network derives from a single charter, and has been removed from analysis below. 
  • 64 – Barthélemy de Jur, bishop of Laon, appearing from 1121-1150.
  • 67 – Roger de Rosoy, bishop of Laon, appearing from 1174-1202.      

Anonymous Canons (4)

By far the largest sub-network centers on the support of a group of unknown canons of the Laon cathedral, spanning a period from 1224 to 1278. It is unclear if this grouping constitutes an innovation or variation in scribal practice or a stylistic trait on the part of de Barthélemy. It is probable that several charters which are attributed to an anonymous canon were issued by one of the other named canons above – Clement de St-Germain, William de Antogniaco, and perhaps Jean de Busancy – and thus the canonry of Laon should be considered as a whole for the purpose of broader analysis.

Clement de St-Germain (11)

One of the canons of Laon, Clement appears in the cartulary as a source of support for individual charters from 1240 to 1244. He is mentioned elsewhere up to 1247, but nothing further is known about him.

Gautier de Mortagne (18)

Gautier was bishop of Laon from 1153-1174, and appears in the charter as a source of support from 1151 to 1178. This latter date is obviously a scribal error, an error by de Barthélemy, or a deliberate fabrication. He has a distinct connection to the lords of Rumigny, specifically Nicolas IV and V, through Samson, archbishop of Reims.

Albéric de Humbert (33)

Albéric de Humbert, Archbishop of Reims, ruled from 1207 to 1218, and appears in the cartulary from 1211 to 1219. This latter date is most likely either a scribal or editorial error, as his death in 1218 is well-attested elsewhere. Albéric is a figure relatively well-attested in the historical record. As archbishop, he was somewhat of a controversial figure; it was rumored he set fire to the Reims cathedral in order to be able to build a more impressive edifice. He was also active in the Albigensian Crusade, appearing in the Chanson de la croisade albigeois at the August 1212 siege of Mossiac, and in the Fifth Crusade (1213-1221). In the Foigny network, he appears as a supporting authority.

Jobert (38)

Jobert, lord of Vénéroles and Mt-St-Hubert, appears in the Foigny cartulary in 1227 only as a significant supporter of the abbey. This small network seems to be based entirely on feudal ties.

Anselm de Mauny (40)

Also known as Anselm de Bercenay, Anselm was bishop of Laon from 1215 to his death on September 3, 1238, and was a member of the family of King Louis IX of France (r.1226-1270). He appears in the cartulary from 1218 to 1235.
