Crisogono; Jean des Bellesmains, Bishop of Poitiers; Pons d'Arsac, Archbishop of Narbonne; and Gerard, Archbishop of Bourges.Roger of Howden may have accompanied him, as he is the source for the only account of the mission and he includes Henry's letter summarising their accomplishments.On the other hand, he also relied heavily on the letters between Henry and Pietro di San Chrysogono.
