the vehmic court system in medieval Germany. In Anglo-Saxon England, juries investigated crimes. After the Norman Conquest, some parts of the country preserved juries as the means of investigating crimes. The use of ordinary members of the community to consider crimes was unusual in ancient cultures, but was nonetheless also found in ancient Greece. The modern jury trial evolved out of this custom in the mid-12th century during the reign of Henry II. Juries, usually 6 or 12 men, were an "ancient institution" even then in some parts of England, at the same time as Members consisted of representatives of the basic units of local government—hundreds (an administrative sub-division of the shire, embracing several vills) and villages. Called juries of presentment, these men testified under oath to crimes committed in their neighbourhood. The Assize of Clarendon in 1166 caused these juries to be adopted systematically throughout the country. The jury in this period was "self-informing," meaning it heard very little evidence or testimony in court. Instead, jurors were recruited from the locality of the dispute and were expected to know the facts before coming to court. The source of juror knowledge could include first-hand knowledge, investigation, and less reliable sources such as rumour and hearsay. Between 1166 and 1179 new procedures including a division of functions between the sheriff, the jury of local men, and the royal justices ushered in the era of the English Common Law. Sheriffs prepared cases for trial and found jurors with relevant knowledge and testimony. Jurors 'found' a verdict by witnessing as to fact, even assessing and applying information from their own and community memory—little was written at this time and what was, such as deeds and writs, were subject to fraud. Royal justices supervised trials, answered questions as to law, and announced the court's decision which was then subject to appeal. Sheriffs executed the decision of the court. These procedures enabled Henry II to delegate authority without endowing his subordinates with too much power. ("Henry II" 293) In 1215 the Catholic Church removed its sanction from all forms of the ordeal—procedures by which suspects up to that time were 'tested' as to guilt (e.g., in the ordeal of hot metal, molten metal was sometimes poured into a suspected thief's hand. If the wound healed rapidly and well, it was believed God found the suspect innocent, and if not then the suspect was found guilty).
