Archbishop Joseph Clemens was a son of Elector Ferdinand Maria of Bavaria and his wife, Henrietta Adelaide of Savoy. He fathered three children and provoked many by bringing their mother to the Bonn Court, though he claimed to no longer have intimate relations with her. He is buried in Cologne Cathedral. The counter-enamel of Ardin's miniature is signed and dated 'Jean Friderich Ardin.. pinxit A.o i7i5..', thus pre-dating by three years the otherwise identically signed version illustrated in W. Holzhausen, Kurkölnische Hofmaler des 18. Jahrhunderts, Cologne, 1957, p. 12, fig. 5. Both enamels are copied after Joseph Vivien's large-scale portrait of the Archbishop-Elector.
