the straightforward one that they were murdered by their uncle who in any case controlled access to them and was therefore regarded as responsible for their welfare. In the period before the boys' disappearance, Edward was regularly being visited by a doctor; historian David Baldwin extrapolates that contemporaries may have believed Edward had died of an illness (or as the result of attempts to cure him). An alternative theory is that Perkin Warbeck, a pretender to the throne, was indeed Richard, Duke of York, as he claimed, having escaped to Flanders after his uncle's defeat at Bosworth to be raised by his aunt, Margaret, Duchess of Burgundy. Bones belonging to two children were discovered in 1674 by workmen rebuilding a stairway in the Tower. On the orders of King Charles II, these were subsequently placed in Westminster Abbey, in an urn bearing the names of Edward and Richard. The bones were re-examined in 1933, at which time it was discovered the skeletons were incomplete and had been interred with animal bones. It has never been proven that the bones belonged to the princes, and it is possible that they were buried before the reconstruction of that part of the Tower of London. Permission for a subsequent examination has been refused. In 1789, workmen carrying out repairs in St George's Chapel, Windsor Castle, rediscovered and accidentally broke into the vault of Edward IV and Elizabeth Woodville. Adjoining this was another vault, which was found to contain the coffins of two children. This tomb was inscribed with the names of two of Edward IV's children who had predeceased him: George, Duke of Bedford, and Mary. However, the remains of these two children were later found elsewhere in the chapel, leaving the occupants of the children's coffins within the tomb unknown. In 1486 Edward IV's daughter Elizabeth, sister of Edward V, married Henry VII, thereby uniting the Houses of York and Lancaster. Epitaph As outlined above, on the orders of Charles II, the presumed bones of Edward V and his brother Richard were interred in Westminster Abbey; Edward was thus buried in the place of his birth. The white marble sarcophagus was designed by Sir Christopher Wren and made by Joshua Marshall. The sarcophagus can be found in the north aisle of the Henry VII Chapel, near Elizabeth I's tomb. The Latin inscription on the urn can be translated as follows: The original
