Camerarius, Joachim: De Philippi Melanchtoni ortu, totius vitae curriculo et morte. Lipisae, 1566 (binding)
Luther and Melanchthon: two different characters, one faith.
The name of these two has been linked so tight that no history of Reformation can discuss one without the other. This link is also symbolised by this German Renaissance binding, the first cover depicting Melanchthon, while the second shows Luther.
