From this extract all that can be gathered with certainty is the popular idea of the opinions John Ball held; and it is instructive to find that in the Primate's eyes there was nothing in the doctrine to warrant the extreme penalty of the law. But in reality we have no certainty as to what Ball actually taught, for in another account we find that, preaching on Corpus Christi Day, June 13, 1381, during the last days of the revolt, far fiercer words are ascribed to him. He is made to appeal to the people to destroy the evil lords and unjust judges, who lurked like tares among the wheat. "For when the great ones have been rooted up and cast away, all will enjoy equal freedom--all will have common nobility, rank, and power." Of course it may be that the war-fever of the revolt had affected his language; but the sudden change of tone imputed in the later speeches makes the reader somewhat suspicious of the authenticity. The same difficulty which is experienced in discovering the real mind of Ball is encountered when dealing with Wat Tyler and Jack Straw, who were, with him, the leaders of the revolt. The confession of Jack Straw quoted in the _Chronicon Angliae_, like nearly all mediaeval "confessions," cannot be taken seriously. His accusers and judges readily supplied what they considered he should have himself admitted. Without any better evidence we cannot with safety say along what lines he pushed his theories, or whether, indeed, he had any theories at all. Again, Wat Tyler is reported to have spoken threateningly to the King on the morning of his murder by Lord Mayor Walworth; but the evidence is once more entirely one-sided, contributed by those who were only too anxious to produce information which should blacken the rebels in the minds of the educated classes. As a matter of fact, the purely official documents, in which we can probably put much more reliance (such as the petitions that poured in from all parts of the country on behalf of the peasants, and the proclamations issued by Richard II, in which all their demands were granted on condition of their immediate withdrawal from the capital), do not leave the impression that the people really advocated any communistic doctrines; oppression is complained of, the lawyers execrated, the labour laws are denounced, and that is practically all. It may be, indeed, that the traditional view of Ball and his followers, which makes them one with the contemporaneous revolts of the Jacquerie in France, the Ciompi in Florence, &c., has some basis in fact. But at present we have no means of gauging the precise amount of truth it contains.
