New Minster, Winchester (see image below). Most charters are only known from later copies, but sixteen survive as single sheets which are or may be originals. Some give Edgar's regnal year, and the start date they were based on varied, with some from 959, 960 and 973, but most often 957. Like Æthelstan, Edgar used the titles king of the English and king of Britain in his charters, and Keynes comments that "the consistent usages of Edgar's reign represent nothing less than a determined reaffirmation of the polity created by Æthelstan in the 930s". Law Four law codes have been attributed to Edgar, but the correct number is two. The Hundred Ordinance was formerly called I Edgar by historians, but it does not say who issued it, and it may date to an earlier king. II and III Edgar are the ecclesiastical and secular sections of one set of provisions, known as the Andover Code. IV Edgar is thus the second code. Edgar was more concerned with the administration of the law than its substance. His primary concern was to ensure that existing laws were properly enforced. Law codes were not unilateral royal pronouncements, but issued with the advice of the king's councillors. The legal historian Patrick Wormald describes the Andover code as impressive and rational. II Edgar covers ecclesiastical matters, especially church dues. For the first time, a specific penalty was prescribed for non-payment of tithes, and anyone who did not pay Romescot, the penny due to the Pope, had to take it to Rome – a penalty theoretical rather than real. III Edgar is concerned with making justice accessible, preventing unjust judgments, standardisation of weights and measures, and that "one coinage is to be current throughout all the king's dominion". Plaintiffs had to exhaust other avenues before they were allowed recourse to the king, judgements had to be just and punishments had to be appropriate. Courts were to be held regularly, and every man was to provide himself with a surety to hold him to his legal duty. The preservation of order required the cooperation of the secular and religious authorities, but it is not until III Edgar that ealdormen and bishops were required to work together in the judgement of legal cases. IV Edgar is more wordy than the Andover code and more rhetorical than any previous one. It has attracted the most attention by historians as
