identification is secure, because of similar likenesses that explicitly name Johann. In the so-called Sächsisches Stammbuch (Sächsische Landesbibliothek, Dresden), with illustrations by the Cranach workshop of about 1540–46, he appears as "Hertzog Johans" next to his wife, Elisabeth of Hesse. A miniature portrait of about 1578–80 by Lucas Cranach the Younger (Kunsthistorisches Museum, Vienna), calls him "H. Hans," and the Latin inscription on a likeness by Monogrammist I.S. describes him precisely as "Johann, Duke of Saxony, son of Georg."
