PMM. Scarce first printing and first folio edition. This milestone in Western culture and religion arguably constitutes the most important work printed in the history of the Catholic Church. "Council of Trent, 19th ecumenical council of the Roman Catholic Church, held in three parts from 1545 to 1563. Prompted by the Reformation, the Council of Trent was highly important for its sweeping decrees on self-reform and for its dogmatic definitions that clarified virtually every doctrine contested by the Protestants. Despite internal strife and two lengthy interruptions, the council was a key part of the Counter-Reformation and played a vital role in revitalizing the Roman Catholic Church in many parts of Europe." (Encycl. Britt.). Ahmanson-Murphy/UCLA 720. Renouard, Alde, 190:4. PMM 82 (this edition is mentioned in this).
