Part II has only one book, the sixth one, covering 31 popes-from Clement V up to Pius V (d. 1572). It was first published in Salamanca in 1573. This second part4is of great interest because the writer was contemporary with the historical events from Paul III’s up to Pius V’s time, which implies that he was a witness to many of them, as he testifies throughout this sixth book, even though his point of view might be at times somewhat marred.
