The court invited many of the greatest magnates and prelates [highest ecclesiastical officials, such as bishops] of the land to the great ecclesiastical festivals, when the king held more solemn courts and feasted with his vassals for several days. These included all the great earls, the majority of bishops, some abbots, and a number of thegns and clerics. Edward had a witan of wise men to advise him, but sometimes the King would speak in the hall after dinner and listen to what comments were made from the mead-benches. As the court moved about the country, many men came to pay their respects and attend to local business. Edward started the practice of King's touching people to cure them of scrofula, a disease which affected the glands, especially in the head and neck. It was done in the context of a religious ceremony. The main governmental activities were: war, collection of revenue, religious education, and administration of justice. For war, the shires had to provide a certain number of men and the ports quotas of ships with crews. The king was the patron of the English church. He gave the church peace and protection. He presided over church councils and appointed bishops. As for the administration of justice, the public courts were almost all under members of Edward's court, bishops, earls, and reeves. Edward's mind was often troubled and disturbed by the threat that law and justice would be overthrown, by the pervasiveness of disputes and discord, by the raging of wicked presumption, by money interfering with right and justice, and by avarice kindling all of these. He saw it as his duty to courageously oppose the wicked by taking good men as models, by enriching the churches of God, by relieving those oppressed by wicked judges, and by judging equitably between the powerful and the humble. He was so greatly revered that a comet was thought to accompany his death. The king established the office of the Chancery to draft documents and keep records. It created the writ, which was a small piece of parchment [sheep skin] addressed to a royal official or dependent commanding him to perform some task for the King. By the 1000s A.D., the writ contained a seal: a lump of wax with the impress of the Great Seal of England which hung from the bottom of the document. Writing was done with a sharpened goose-wing quill. Ink was obtained from mixing fluid from the galls made by wasps for their eggs on oak trees, rainwater or vinegar, gum arabic, and iron salts for color.
