made Chancellor of the Apostolic See under Lucius II and Eugenius III, and who likewise lies a little outside our limits. His history has yet to be worked out ; but as he is, like John of Salisbury, a historical link of some importance, I must say a word or two about him. We know from a letter of S. Bernard addressed to Ascelin, Bishop of Rochester, between the years 1142 and 1148, that Robertus Pullus was at that time studying with great success in the University of Paris ; he was then, it would appear from the Rochester Fasti, Archdeacon of Rochester ; and S. Bernard's petition to the Bishop, that he might be allowed to pursue his studies at Paris, is thus quite in character with the usual practice for an archdeacon to go and study for some time in a foreign university before he began the formal exercise of archidiaconal functions. In 1146, or thereabouts, Robert was still at Paris teaching theology, and there John of Salisbury attended his lectures during the last two of the twelve years, dating from 1136, that his education was in progress. If these dates are accurate, it is a little difficult to identify him with the person who appears as Chancellor of the Apostolic See in 1145 and 1146. It is not impossible that he was then for a short time transferred to Rome ; this, however, will leave no time for his teaching divinity, as he is said to have done, at Exeter and Oxford. He is mentioned as Chancellor of the Apostolic See by the contemporary writer John of Hexham, who dates him in 1146. Anyhow, he was a man of great mark ; that we know from S. Bernard and John of Salisbury, and from his extant works, Sentences, and Sermons. But there was another Robert, also connected with Rochester, also an Italian Chancellor, and mentioned as a distinct person by the same historian of Hexham. He was a native of ' Salesby,' whether Selby or Salisbury I shall not decide, who tried his fortunes in Sicily and became chancellor to King Roger about the same year 1146. Is.it
