The Gloucester Tables Set was discovered in the 1980s, and has proved to be the oldest complete backgammon set in existence. That alone is remarkable but with every element  (including the board) decorated, it is a rare example of portable art in the style known as Romanesque. Made and lost during the early Norman period, around 1100, the set is an international treasure.

The talk looks into the designs of some of the playing pieces and shows how some can be related to imagery around Europe, while others are apparently unique.

Whose set was it? I consider this question and also the significant mystery - why was such an extravagant and valuable piece of property smashed up and thrown away?
