Was Catherine of Aragon's marriage to Arthur Tudor ever consummated? Alison Weir's book 'The Six Wives of Henry VIII" implies that the marriage between Catherine and Arthur had not been consummated: "she was a religious woman of sound principles; it is far likely therefore that she was guilty of deception than she was telling the truth". However, Joanne Denny provides some evidence that the marriage was consummated "for clearly somebody [Arthur] had been worried enough about the fact that the bride was not yet pregnant to write to Rome" about her excessive "religious" practices that might have prevented pregnancy ('Anne Boleyn: A new Life of England's Tragic Queen'). Denny also mentions that Catherine might have lied to Henry VII and the court about her first pregnancy - is it possible that Catherine was not truthful?
