In seventeenth-century Habsburg-Ottoman diplomatic relations, grand embassies played a crucial role in preserving the peace between the two empires. In the last decade, they have gained some popularity as a subject of historical research. Th e grand embassy of Johann Rudolf Schmid zum Schwarzenhorn (1650-51), however, has thus far received only little attention. Th is paper aims to analyse symbolic communication between Habsburgs and Ottomans during Schmid's mission by examining its three main events: the border exchange ceremony, the entry into Constantinople, and the audience with the sultan.
