 Jocelin commissioned his namesake Jocelin of Furness, the same man who had written the "Life of St. Waltheof", to write a "Life of St. Kentigern", a task all the more necessary because, after 1159, the Papacy claimed the right to canonise saints.Kentigern, or Mungo as he is popularly known, was the saint traditionally associated with the see of Glasgow, and his status therefore reflected on Glasgow as a church and cult-centre.There had already been a cathedral at Glasgow before Jocelin's episcopate.
