The words of a contemporary writer (Pandulph. Pisan. in Vit. Paschal. II. p. 357, 358) describe the election and oath of the praefect in 1118,
inconsultis patribus .... loca præfectoria .... Laudes præfectoriæ.... comitiorum applausum ....
juraturum populo in ambonem sublevant .... confirmari eum in urbe præfectum petunt.
