You can see the folk process even on this thread, or is it the curse of the internet? The "Princes in the Tower" weren't found a few years ago, or in the 1930s.

The story goes back to 1674 when some workmen in the Tower of London found a box containing bones, and according to some accounts, rags and velvet. Apparently Charles II ordered them interred in the Lady Chapel of Westminster Abbey - they are in an urn supposedly designed by Christopher Wren. This has an inscription including "stifled with pillows ... by the order of their perfidious uncle Richard the Usurper".

This urn was reopened in 1933 and found to contain human, chicken and other animal bones. And some nails. No identification was possible.

There is loads of other info not to mention immense steaming piles of idle speculation on the Web, about both the Princes and Richard III. Even the Wikipedia entry on the princes seems to be compiled mostly from secondary sources.

It's all very interesting though, especially as I live near Leicester. As Martin Carthy's on at the Guildhall next month, will have to have a look at the Richard III exhibition there which has almost magically appeared at just the right time.
