Robert of Caiazzo

Robert (died 1116) was a south Italian nobleman who ruled the counties of Airola, Alife, Caiazzo, Sant'Agata and Telese from 1088 until his death.

Robert's father, Rainulf I, received several counties in the north of the principality from his cousin, Prince Jordan I, in 1078.

[2] In a charter of 4 July 1066, Jordan I and his father, Richard I, refer to the "treason of the counts of Caiazzo" to justify the redistribution of confiscated lands.

[13] During the brief recovery of Capua, on 27 January 1093 Robert, described as Richard's magister (master), "persuaded" the prince to make a donation to the abbey of Sant'Angelo in Formis.

The last charter in which Robert explicitly recognised Richard's lordship is dated 1105, at which time they were on a joint military campaign in the north of the principality.

After this isolated instance of a pragmatic acknowledgement on Robert's part, the count of Caiazzo was de facto independent of Capuan authority.

Shortly afterwards, both Robert and Richard swore oaths before Abbot Oderisius I to defend Pontecorvo from the abbey's enemies.

[19] This precipitated a major feud between Monte Cassino and the nuns of Santa Maria de Capua, who had formerly held authority over Cingla.

[4] In Robert's words, he did it "for the health of my soul and good memory of my father, Count Ranulf, and all my relatives"[21] after hearing that the monastery in Cingla was "for a long time ... devastated and dissipated by bad men and the service of God too carelessly performed there".

[23] Shortly after donating the monastery of Cingla to Monte Cassino, Robert swore to be faithful to Abbot Oderisius and pledged to defend the terra Sancti Benedicti against all opponents save his lords, Prince Richard and Count Hugh of Molise.

[4] He commissioned the abbot of Monte Cassino, Oderisius I, to prepare a biography of Menna and an account of the translation of his relics.

Oderisius gave the task to his librarian, Leo of Ostia, who reworked the Vita Sancti Mennatis of Gregory the Great and added his own Translatio to it.

[26] Leo notes that while Robert could have had the books he wanted prepared "in his own court" (in curia sua), implying that he had a scriptorium and employed skilled scribes, he preferred to commission Monte Cassino because of his piety.
