An abridged summary of the continuation of Burchard's Diarium by Paris de Grassis, master of ceremonies under popes Julius II and Leo X, covering the pontificate of Leo X up to 1521, followed by a further continuation by Blasius Martinellus up to 1538 (and thus encompassing Adrian VI, Clement VII, and part of Paul III). By far the largest section is devoted to 1513, the year of Leo's accession, with the amount given to each year declining sharply thereafter until 1538 receives only half of a page. Written in Italy.
