A high flier?
Collini came from an old Florentine noble family. In 1749, he left his study of the law and his connections to his home city and traveled to Prussia. In Berlin, the destitute Collini met Voltaire. As his personal secretary, he accompanied him to Mannheim and Schwetzingen in 1753. With the help of the famous philosopher, he finally received a place as a confidential secretary to the prince-elector at the court of Prince-Elector Carl Theodor in 1760.
