Arnold,
of Melchthal, patriarch of the forest cantons of Switzerland. He was in love with Matilda, a sister of Gessler, the Austrian governor of the district. When the tyranny of Gessler drove the people into rebellion, Arnold gave up Matilda and joined the insurgents; but when Gessler was shot by William Tell, he became united to her in marriage.
