Count Guidobald Thun (1616 Castelfondo-1668 Salzburg), Prince-Archbishop of Salzburg (1654-1668)

Schönfeld portrayed Guidobald during the period between confirmation of his election as Archbishop of Salzburg by Pope Innocent X on 4 May 1654 and his consecration on 24 September 1654. With an air of self-assurance, the 38-year-old Guidobald leans with his left hand on the small table, showing to advantage the details of the pushed-up sleeve of his rochet and his ring. Chalcedony, the birthstone of Sagittarius, is said to confer self-confidence and authority, and to banish melancholy. When his coffin was opened in 1957 the striking chalcedony ring was on his right ring-finger.
Schönfeld signed the work on the letter lying on the table, and gives details in the cartouche of Guidobald’s election on 3 February and its confirmation on 4 May 1654, including the subject’s age below: "AETATIS SVAE XXXVIII". This painting was part of the exhibition for the opening of the Residenzgalerie in 1923.
