The courts of justice were traps, in which the innocent were caught. The judges were almost as malicious and cruel as though they had been bishops or saints. There was no trial by jury, and the rules of evidence allowed the conviction of the supposed criminal by the proof of suspicion or hearsay. The witnesses, being liable to be tortured, generally told what the judges wished to hear. The supernatural and the miraculous controlled the world. Everything was explained, but nothing was understood. The church was at the head. The sick bought from monks little amulets of consecrated paper. They did not send for a doctor, but for a priest, and the priest sold the diseased and the dying these magical amulets. These little pieces of paper with the help of some saint would cure diseases of every kind. If you would put one in a cradle, it would keep the child from being bewitched. If you would put one in the barn, the rats would not eat your corn. If you would keep one in the house, evil spirits would not enter your doors, and if you buried them in the fields, you would have good weather, the frost would be delayed, rain would come when needed, and abundant crops would bless your labor. The church insisted that all diseases could be cured in the name of God, and that these cures could be effected by prayers, exorcism, by touching bones of saints, pieces of the true cross; by being sprinkled with holy water or with sanctified salt, or touched with magical oil. In that day the dead saints were the best physicians; St. Valentine cured the epilepsy; St. Gervasius was exceedingly good for rheumatism; St. Michael for cancer; St. Judas for coughs and colds; St. Ovidius restored the hearing; St. Sebastian was good for the bites of snakes and the stings of poisonous insects; St. Apollonia for toothache; St. Clara for any trouble with the eyes; and St. Hubert for hydrophobia. It was known that doctors reduced the revenues of the church; that was enough--science was the enemy of religion. The church thought that the air was filled with devils; that every sinner was a kind of tenement house inhabited by evil spirits; that angels were on one side of men and evil spirits on the other, and that God would, when the subscriptions and donations justified the effort, drive the evil spirits from the field. Satan had power over the air; consequently he controlled the frost, the mildew, the lightning and the flood; and the principal business of the church was with bells, and holy water, and incense, and crosses, to defeat the machinations of that prince of the power of the air.
