Heidelberg Castle
As the first Calvinist pastor in the parish of Dittelsheim, he undertook a trip to Heidelberg, the centre of Calvinist theology in Germany. Praetorius was so impressed by the Great Wine Barrel in Heidelberg Castle that he published a poem with the title "Vas Heidelbergense" in October 1595, praising its size as an apparent proof of the superiority of the Calvinist religion.
