Oracle bones star in Potter display

The British Library has unveiled its oldest artifact in an exhibition dedicated to the fictional Harry Potter, and the origins of "magic".

The Chinese oracle bones included in the display are more than 3,000 years old and were used in attempts to foretell the future.

The bones arrived at the British Library along with the Couling-Chalfant Collection, which was put together in China between 1903 and 1908 by two missionaries, Samuel Couling and Frank Chalfant.
