Note 1580 — Chapter XI · THE LAST YEARS OF ARCHBISHOP THEOBALD. 1156–1161.
Reading edition
He himself makes it twenty years (Joh. Salisb. Metalog., prolog. l. iii., Giles, vol. v. p. 113); but he cannot possibly have left Paris before 1147, and the Metalogicus was finished before Theobald’s death in 1161. Either there is something wrong in John’s reckoning, or in his copyist’s reading of it, or this passage was added some years after the completion of the book.
