Clement XII, original name Lorenzo Corsini  ( born April 7, 1652 , Florence—died Feb. 6, 1740 , Rome )  pope from 1730 to 1740.


Despite ill health and total blindness (from 1732), he worked diligently sought to halt the decline of papal influence but was far from successful. Although his protests against the spread of Gallicanism (an essentially French doctrine advocating restriction of papal power) to Spain were fruitless, his enforcement of Pope Clement XI’s bull Unigenitus of 1713 sustained the suppression of Jansenism (a heretical doctrine deemphasizing freedom of the will and teaching that redemption through Christ’s death is open to some but not all).

Clement aided large missionary enterprises, as exemplified in his sending Franciscans to Ethiopia, but he continued Clement XI’s ban on the Chinese and Malabar rites—irites—i.e., those Far Eastern ceremonies honouring Confucius and one’s forefathers. In Rome he erected the Trevi fountain.

On April 28, 1738, he promulgated his bull In Eminenti, which condemned Freemasonry, the beliefs and observances of which were considered pagan and unlawful by the Roman Catholic Church. The Masons were often hostile to the church, and Clement threatened to excommunicate any Catholic who joined.
