This jewellery box is a handmade piece, crafted out in wood and veneered with partridge's eye wood. Its decoration is made with different noble woods such as satinwood, ironwood, rosewood, holly and maple wood, chestnut wood, ash wood, elm tree root and olive root, boxwood wires, ebony wood and treated cow bone. Due to the symbology of the shape used to decorate the lid of the jewellery box, the author called it Pythagoras.
Geometrically, the jewellery box is a rectangular prism. The shape used to decorate the lid illustrates one of the simple proofs of the Pythagoras theorem "The square of the hypotenuse is equal to the sum of the squares of the legs”.
