existence. Philip Hyacinth (1680–1734), 4th Prince Lobkowicz, was a patron of the arts who collected musical scores on several journeys to England. The composer Sylvius Leopold Weiss, one of the finest lutenists of his day, taught music to both Philip Hyacinth and his second wife Anna Maria Wilhelmina von Althan, and dedicated several works to the princess. Eleonore, Princess Lobkowicz (1682–1741) was the daughter of Ferdinand August, 3rd Prince Lobkowicz. At the beginning of the 18th century, she had the mineral spring at Bílina cleaned, leading to the town becoming a well-known spa. In 1701 she married Adam Franz Eusebius, hereditary Prince von Schwarzenberg, whom Emperor Charles VI killed in a hunting accident in 1732. Subsequently, the Emperor took her son Joseph Adam to his court in Vienna, and she was paid a baronial maintenance of 5,000 gulden. Eleonora Carolina (1685–1720), Countess of Bílina. The daughter and sole heir of Count Wenzel Ferdinand, she married her distant cousin Philip Hyacinth, 4th Prince Lobkowicz. Georg Christian, Fürst von Lobkowicz (1686–1755). A field marshal of the Imperial forces, Georg Christian was the fourth son of Ferdinand August, 3rd Prince Lobkowicz. He commanded the Lobkowicz regiment founded during the Thirty Years' War by Václav Eusebius, 2nd Prince Lobkowicz, and was commander-in-chief of the Habsburg armies in Italy. The Lobkowicz Collections holds portraits of eighteen officers that served in the Lobkowicz regiment under his command. Ferdinand Philip (1724–1784), 6th Prince Lobkowicz. After Frederick the Great of Prussia invaded Silesia during the War of the Austrian Succession, Ferdinand Philip supported Frederick over Empress Maria Theresa of Austria in order to protect his huge and highly profitable Silesian estate, originally acquired by Václav Eusebius, 2nd Prince Lobkowicz. It was probably for this reason that he was one of only two reigning princes of Lobkowicz not to be awarded the Order of the Golden Fleece, the highest Austrian order of chivalry. Wishing to avoid the war in Silesia and Bohemia but unwelcome at the Habsburg court in Vienna, Ferdinand Philip spent much of the 18th century in England, accompanied by Christoph Willibald Gluck, whom he had employed in the Lobkowicz Palace orchestra. He returned to Bohemia with two of Canaletto’s finest paintings of London. His shrewd protection of his Silesian estate paid off: after his death, it was sold to the Duke of Courland for the incredible (at the time) sum of one million gulden. Joseph František
