De Principibus iuventutis Caesaribus, &
nobilissimis Caesaribus.
Aa 1.1 custome was receaued amongst the Romane Em∣perours in their life time to nominate him whom they would haue to succeed them in their Empire: & him they called Princeps iuventutis Caesar, and Nobilissimus Caesar. The like custome was practised by Charles the fifth Emperour of Germany, and so hath beene continued by his successors; namely, that one should be chosen whom they called Rex Romanorum, who should be so farre invested in the title to the Empire by the meanes of the present Em∣perour, that vpon the death, resignation, or deposition of the then being Emperour, he immediatly should succeed.
