Note 1076 — Chapter VII · THE ENGLISH CHURCH. 1136–1149.
Reading edition
From the way in which this trial is brought into the Hist. Pontif., it would at first glance seem to have taken place in 1151. But the presence of Bishops Ulger of Angers and Roger of Chester, both of whom died in 1149, and the account of the proceedings written by Gilbert Foliot to Brian Fitz-Count clearly prove the true date to be 1148.
