Yet there are obvious reasons for closely criticising the accusations against King Richard, and for examining them with more than ordinary care before accepting them as proved. For his successor had no valid title to the crown. It was not only the new King's interest, but a necessity of his position, that he should cause grave charges to be brought against his predecessor, and that they should be accepted as true. Henry VII. had the power and the will to silence all comment, and to prevent any defence from being published. Evidence in favour of Richard was destroyed. Authors employed by Henry, and others who were anxious to please him and his successors, were alone permitted to write histories. Not a syllable was allowed to be uttered on the other side for one hundred and sixty years. The story thus put forward was dramatised by Shakespeare, and became so familiar to posterity that even writers of our own day approach the subject with unconscious prejudice which they cannot resist. If Richard performs kindly acts, and many such are recorded, he is trying 'to get unsteadfast friends.' If he punishes treason he is 'a venomous hunchback.' If a rebellion is put down during his reign he is an inhuman tyrant. His ability is cunning, his justice is cruelty, his bravery is fury, his generosity is artfulness, his devotion is hypocrisy. In giving some account of the original authorities upon whose testimony the charges against King Richard rest, I only propose to state general conclusions with regard to them in the present chapter; because proofs {168} and arguments will be embodied in the detailed discussions which follow. Bernard André, Archbishop Morton, and Polydore Virgil were actually in the pay or under the direct influence of the first Tudor King. In this trio only one was an Englishman. John Rous and Robert Fabyan wrote during Henry's reign, accepted his version of events, and sought his favour. The continuator of the Chronicle of Croyland Abbey is the sole independent source of information. [Sidenote: Morton's pamphlet]
