The Basle case was a very singular one. A farm-yard cock was tried on the absurd charge of having laid an egg. It was contended in support of the prosecution that eggs laid by cocks were of inestimable value for use in certain magical preparations; that a sorcerer would rather possess a cock's egg than the philosopher's stone; and that Satan employed witches to hatch such eggs, from which proceeded winged serpents most dangerous to mankind. On behalf of the gallinaceous prisoner, the facts of the case were admitted, but his advocate submitted that no evil animus had been proved against his client, and that no injury to man or beast had resulted. Besides, the laying of the egg was an involuntary act, and as such not punishable by law. If it was intended to impute the crime of sorcery to his client, he was entitled to an acquittal; for there was no instance on record of Satan having made a compact with one of the brute creation. In reply, the public prosecutor stated that, though the Evil One did not make compacts with brutes, he sometimes entered into them; and though the swine possessed by devils, as related by the Evangelists, were involuntary agents, yet they, nevertheless, were punished by being caused to run down a steep decline into the Lake of Galilee, where they were drowned. The poor cock was convicted, and condemned to death, not as a cock, however, but as a sorcerer, or perhaps a devil, in the form of a cock, on which finding it was, with the egg attributed to it, burned at a stake, with all the form and solemnity of a judicial execution. As the lower animals were amenable to the law in Switzerland in those dark ages, so, in certain circumstances, they could be put into the witness box. If a house was broken into between sunset and sunrise, and the occupier killed the intruder, the act was regarded as justifiable homicide. But it was thought right to provide by law against the case of a man, living alone, who might invite a person whom he wished to kill to spend the evening with him, and having slain him, might assert that he committed the act in self-defence, or to protect his property, the dead man having been a burglar. Therefore, when a man was killed in such circumstances, the occupier of the house was required to produce some domestic animal that was an inmate of the house, and had witnessed the tragedy, and to declare his innocence on oath in the presence of such animal. If the brute witness did not contradict him, he was acquitted; the law taking it for granted that God, rather than allow a murderer to go unpunished, would intervene by causing a miraculous manifestation by the mouth of a dumb witness.
