Beaune Altarpiece Beaune Altarpiece The Beaune Altarpiece (c. 1445–50), often called The Last Judgement, is a large polyptych altarpiece by the Early Netherlandish artist Rogier van der Weyden. It was painted in oil on oak panels, with parts later transferred to canvas. It consists of fifteen paintings on nine panels; six are painted on both sides. It retains some of its original frames. Six outer panels (or shutters) are hinged; when folded they show an exterior view of saints and the donors. The inner panels contain scenes from the Last Judgement arranged across two registers.

Hinged dissection Hinged dissection A hinged dissection, also known as a swing-hinged dissection or Dudeney dissection, is a kind of geometric dissection in which all of the pieces are connected into a chain by "hinged" points, such that the rearrangement from one figure to another can be carried out by swinging the chain continuously, without severing any of the connections. Typically, it is assumed that the pieces are allowed to overlap in the folding and unfolding process; this is sometimes called the "wobbly-hinged" model of hinged dissection. The concept of hinged dissections was popularised by the author of mathematical puzzles, Henry Dudeney.
