Theodore Freylinghuysen Collier, 1911 Encyclopædia Britannica, Volume 6… (1911)
“ A contemporary account of Clement was written by Augustin de Andrès y Sobiñas, . . . el nacimiento, estudios y empleos de . . . Clem. XIII. (Madrid, 1759) . Ravignan’s Clement XIII. e Clement XIV. (Paris, 1854) is partisan but free from rancour; and appends many interesting documents. See also the bibliographical note under Clement XIV. infra.; and the extended bibliography in Hergenröther, Allg. Kirchengesch. ”
