I came upon the following wonderful painting by Sofonisba Anguissola, ‘The first great woman artist of the renaissance,’ of her sisters playing chess (painted 1555).
The painting is truly sublime. Chess players will notice, however, that the color of the squares on the board is the opposite from what is usually used in modern games, with light on the right, and so it made me wonder about the history of this convention. When did the light-on-the-right convention come into prominence? Has it been long established that way? Is this painting illustrating a different custom at that time, or rather might it be explained by an artist inventing a scene and not aware of the custom?
