Like his father, he was a friend and supporter of lute music and an active lutenist, composing several works for the lute. He also contributed important works to the Roudnice Lobkowicz Library.[2]
One of his friends at the Viennese court was the lutenist Silvius Leopold Weiss. Christoph Willibald Gluck's father was a forester in the service of Phillip Hyacinth in Jezeří. During his time in Vienna, Phillip Hyacinth supported Gluck from 1729 onwards. With Phillip Hyacinth's stepbrother, Georg Christian of Lobkowicz, he travelled through Europe, which took him to London. Gluck dedicated operas La Sofonisba (1744), Ipermestra (1745) and a pasticcio (1743) to him. Phillip Hyacinth founded what was then an important band for the Loreta monastery in Prague.[3]
Personal life
On 17 October 1703, Lobkowicz married Countess Eleonore Karoline von Lobkowicz auf Bílina (1684–1720), a daughter of Wenzel Ferdinand Popel von Lobkowitz (the Habsburg Envoy to France). Before her death on 3 March 1720, the couple had one son:
Ferdinand von Lobkowicz (d. 1704), who died young.
After the death of his first wife, he married Countess Maria Wilhelmine von Althann (1704–1757) on 25 August 1721. She was a cousin of Count Gundaker Ludwig von Althann. Together, they were the parents of:
Marie Anne von Lobkowicz (1725–1729), who died young.
Anne Maria Elisabeth von Lobkowicz (1726–1786), who married diplomat Count Anton Corfiz von Ulfeldt, in 1743.[5]
Philip Joseph von Lobkowicz (1728–1729), who died young.
Charles Joseph von Lobkowicz (1732–1734), who died young.
The Prince of Lobkowicz died on 21 December 1734 in Vienna and was succeeded by his eldest surviving son, Wenzel Ferdinand. He died, unmarried, in 1739 and the title passed to his younger brother, Ferdinand.
