A formal inquiry designed to prove and put upon record the blameless characters of judges, advocates and jurors. In order to effect this purpose it is necessary to supply a contrast in the person of one who is called the defendant, the prisoner, or the accused. If the contrast is made sufficiently clear this person is made to undergo such an affliction as will give the virtuous gentlemen a comfortable sense of their immunity, added to that of their worth. In our day the accused is usually a human being, or a socialist, but in mediaeval times, animals, fishes, reptiles and insects were brought to trial. A beast that had taken human life, or practiced sorcery, was duly arrested, tried and, if condemned, put to death by the public executioner. Insects ravaging grain fields, orchards or vineyards were cited to appeal by counsel before a civil tribunal, and after testimony, argument and condemnation, if they continued in contumaciam the matter was taken to a high ecclesiastical court, where they were solemnly excommunicated and anathematized. In a street of Toledo, some pigs that had wickedly run between the viceroy's legs, upsetting him, were arrested on a warrant, tried and punished. In Naples and ass was condemned to be burned at the stake, but the sentence appears not to have been executed. D'Addosio relates from the court records many trials of pigs, bulls, horses, cocks, dogs, goats, etc., greatly, it is believed, to the betterment of their conduct and morals. In 1451 a suit was brought against the leeches infesting some ponds about Berne, and the Bishop of Lausanne, instructed by the faculty of Heidelberg University, directed that some of "the aquatic worms" be brought before the local magistracy. This was done and the leeches, both present and absent, were ordered to leave the places that they had infested within three days on pain of incurring "the malediction of God." In the voluminous records of this cause celebre nothing is found to show whether the offenders braved the punishment, or departed forthwith out of that inhospitable jurisdiction.
