The letter is dated 1695,and is signed by the future Pope Clement XI as Cardinal Albani. It is untranslated.
Giovanni Francesco Albani was born in Urbino in 1649 to an aristocratic Umbrian family originally from Albania. He received a classical education, studying at the Academy of the deposed Queen Christina of Sweden in Rome. He received doctoral degrees in canon and civil law. By the age of eighteen he was a published author having translated several Greek manuscripts into Latin. In 1677 he entered the curial service and rose rapidly due to his intellectual prowess and high moral standards. His first appointments were to governorships in the Papal States, then as Secretary of Briefs in 1687 and as cardinal deacon in 1690. A very influential man during both Alexander VIII’s and Innocent XII’s papacies, it was Albani who drafted Innocent’s famous bull outlawing nepotism. He was not ordained to the priesthood until September of 1700.
Two months later, on November 23, 1700, he was elected Pope.
