The works of Rousseau, Voltaire, and others, who were then endeavouring by their writings to bring about a reform in the political and moral conditions of society, warmed his imagination, and he, Lavater, Jacob and Felix Hess, (who were not less influenced,) were determined to exert themselves, to benefit those of their native city. An opportunity was soon presented to their active minds. Rumour had been for some time busy with the character of a ruling magistrate, the high land-bailiff Grebel, ascribing to him various acts of tyranny and oppression, and among others, that of appropriating to himself property, and bidding defiance to the rightful owners. This he considered he might do with impunity, not only by the power which he possessed from his high situation, but also from that which he derived from his father-in-law, who was the burgomaster of Zurich. The young friends made diligent inquiries into these charges, and found that there were ample grounds to justify the reports which were current. Their indignation was aroused, and they sent an anonymous letter to the magistrate, threatening him with instant exposure if he did not restore the property. Grebel, relying too much upon the feeling of security which power creates, took no notice of this letter. Upon which Fuseli, and Lavater in particular, excited farther by his contempt, resolved to make the cause of the injured party their own, and accordingly wrote a pamphlet, entitled, "The Unjust Magistrate, or the Complaint of a Patriot," in which they detailed, in forcible and glowing terms, the acts of oppression which had been committed, and called upon the Government to examine into the facts, and punish the offender. This pamphlet they industriously circulated, and took care that it should fall into the hands of all the principal members of the government. The manly tone in which it was written, and the facts adduced in support of the accusation, made such an impression on the council of Zurich, that it was stated from authority, if the author would avow himself, all the circumstances should be inquired into, and the facts carefully examined. Upon this, Fuseli and Lavater, who were the ostensible persons, boldly stepped forward, and acknowledged themselves the authors. Evidence was taken, and the truth of the accusation established to its utmost extent. An upright judgment was awarded; the property restored; and the guilty magistrate then absconded, to avoid the personal punishment so justly due to his crimes.
