Thomas Cajetan
Spalatin accompanied Frederick to the Diet of Augsburg in 1518, and shared in the negotiations with the papal legates, Thomas Cajetan and Karl von Miltitz. He was with the elector when Charles V was chosen emperor and crowned and at the Diet of Worms, through all the troubled diplomacy of the earlier years of the Reformation. Spalatin dissuaded Luther repeatedly from publishing books or engaging in overt acts against the papacy, but was ready to translate the books or justify the acts when they were done.
