John Frederick, Duke of Brunswick-Lüneburg
Palm Tree on Rock
John Frederick, born on April 25, 1625 and died on December 18, 1679, was a duke of Brunswick-Lüneberg. As a youth, he made several trips abroad, and had a special fondness for Italy. In 1651, he travelled to Rome and converted to the Roman Catholic faith. He employed Gottfried Wilhelm von Leibniz, mathematician and philosopher, as Privy Councillor and librarian of the ducal library. From 1665 until his death, he ruled over the Principality of Calenberg. Regarding the Duke's impresa on the reverse of this medal, Leibniz wrote: The true glory of a man rises from hard things, as the loaded palm raises its head out of the rock.
