Albert, Prince (1819-61; German/English), after a follower of Agostino Carracci (1557-1602; Italian) 
Eagles 1841
Etching on chine collé, 22.8 x 15.2 cm (image and plate), 43.4 x 29.9 cm (sheet)
Gift of Queen Victoria, 1893
National Gallery of Victoria (p.192.6-1)

This print, which demonstrates considerable technical skill, is inscribed (on the plate) “Albert 28/8 41” and “after H. Carracci.”

The source, followed closely, is a drawing in the British Royal Collection, now identified as from Agostino Carracci’s circle, and dated to the 1620s. Rudolf Wittkower (1952), while listing the drawing under Agostino himself, commented that it reveals “a meticulous realism foreign to his style.”

Albert’s inscription points to the fact that the drawing was believed at the time he copied it to be by Agostino’s more famous older brother Annibale Carracci (the equivalent of whose name, in English, is Hannibal). The birds resemble those accompanying or symbolizing Jupiter in the Farnese Ceiling frescoes in Rome, completed mainly by Annibale.
