CORRADINI, PIETRO MARCELLINO. — Cardinal, born at Sezze in 1658, died at Rome on 8 February 1743. Of humble origins, he earned in the Curia a reputation as an excellent jurist. He served as auditor to Cardinal Pamphili, as subdatary under Innocent XII and later under Clement XI. He was created cardinal by the latter on 18 May 1712 and in 1718 became prefect of the Sacred Congregation of the Council; he was entrusted with all major affairs, which he always handled with great integrity. He took part in the founding of the hospital of S. Gallicano. In the conclave of 1730 he was excluded from the papacy through the intervention of the King of Spain. To him is owed a *Storia della città di Sezze e Vetus Latium profanum et sacrum* (12 vols., Rome 1704–45).
From 25 December 1734 he was bishop of Frascati; he was buried in S. Maria in Trastevere, where a fine monument was erected to his memory.
