Europe
Zofia was reportedly a sensational success when being introduced to the aristocracy by her spouse in the drawing room receptions of Europe in the palaces of Berlin and Hamburg, Vienna, Rome, Venice and, most famously, in Paris. She was celebrated as "The most beautiful woman in Europe" and known for her expression: "My eyes aches". Her beauty as well as her ability to improvise herself out of difficult situations resulted in widespread admiration. She further gathered notoriety by engaging in affairs with powerful personalities. She was regarded as fashionable at every party in high society in the cities they visited, and was courted by monarchs and ministers.
At the beginning of their European tour, the couple visited Warsaw. In early March 1781, she was called to court to be introduced to King Stanisław II Augustus. After Warsaw, they visited Berlin, where Zofia was introduced to the King of Prussia Frederick II. In the resort town of Spa, Zofia was introduced to the Austrian Emperor Joseph II, who was reportedly so fascinated and impressed by her that he ordered Mozart to compose music on the Turkish harem theme. In one of his letters to his sister, the French queen Marie Antoinette, Joseph II recommended the Witte couple to her.
Zofia saw Marie Antoinette at Petit Trianon, which at that time was being rebuilt in a landscaped park. This was possibly what inspired Zofia later in life to create a similar park. Reportedly, Marie Antoinette was charmed by her and spoke of Zofia as her adopted daughter. While staying in Paris, Zofia became the lover of both of the French king's brothers; the Count of Provence, later King Louis XVIII, and the Comte d'Artois, the future French king Charles X respectively.
In Paris, on 17 November 1781, Zofia gave birth to a son. After this news reached the Polish king, she traveled to meet him at Kamianets where he congratulated her father-in-law, still commandant of the fortress, on the birth of a grandson. The king also promoted the man to the rank of Lieutenant General, and volunteered to be the godfather of the newborn.
