Floor tiles - so called Leonardo tiles

Hexagonal, showing a hollow dice. The sides are painted in blue, ochre and white. The inner edges of the hollowed forms are painted in green and ochre. The sides of the dice and the outer edges are contoured with manganese. The effect of this is to make it appear as if the hollow dices are three-dimensional against a dark manganese background. The makers of this tile must have been Haban, although the technique of decoration was originally Italian. There are 456 hexagonal, 56 triangular and 54 broken remnants of tiles in the collection of the Budapest Museum of Applied Arts.

The simplicity of the range of colours enhances the motif borrowed from Luca Pacioli's treatise De divina proportione (Venice, 1509). The geometrical design was hollowed out of the clay before it was fired. One of the pieces bears an inscription in German.
