Sendivogius was not at all disposed to put up with such treatment without an effort to obtain redress, so he went at once to Prague, and laid his complaint before the Emperor. The Emperor at once sent an express to the prince, ordering him to deliver up Muhlenfels and his plunder. Alarmed at the aspect that things were now assuming, the prince, treacherous to one man as he had been to the other, erected gallows in his courtyard and hanged Muhlenfels with a thief on either side of him. He sent back the jewelled hat, the medal and chain, and the book in manuscript; the powder, he said, he knew nothing of. Sendivogius now adopted a different mode of living altogether to that which he had formerly been addicted to; he pretended to be excessively poor, and would sometimes keep his bed for weeks together, to make the people conclude it was impossible for him to be the owner of the philosopher's stone. He died in the year 1636, upwards of eighty, and was buried at Gravarna. Now, it is commonly held by most people, who have studied the subject, that there is a close and intimate connection between the Alchymists and the Rosicrucians; probably this is true, and a perusal of the works of John Heydon, and others of a similar character, will deepen the impression. It was, indeed, during the life of Sendivogius that the Rosicrucians first began to make a mark in Europe, and cause anything approaching to a sensation. A modern writer says:--"The influence which they exercised upon opinion during their brief career, and the permanent impression which they have left upon European literature, claim for them especial notice. Before their time alchemy was but a grovelling delusion; and theirs is the merit of having spiritualised and refined it. They also enlarged its sphere, and supposed the possession of the philosopher's stone to be, not only the means of wealth, but of health and happiness, and the instrument by which man could command the services of superior beings, control the elements to his will, defy the obstructions of time and space, and acquire the most intimate knowledge of all the secrets of the universe."[1]
