Giuseppe Guarneri was an Italian luthier from the Guarneri house of Cremona. He rivals Antonio Stradivari (1644–1737) with regard to the respect and reverence accorded his instruments, and he has been called the finest violin maker of the Amati line. Giuseppe is known as del Gesù because his labels incorporated the nomina sacra, I.H.S. (iota-eta-sigma) and a Roman Cross. His instruments diverged significantly from family tradition, becoming uniquely his own style. They are considered second in quality only to those of Stradivari but are also claimed by some to be superior.
