It’s easy to underestimate the power of the square, so simple and familiar are its proportions. But it’s worth noting that, with the circle and the triangle, the square forms the basis of so-called ‘Sacred Geometry’, the three shapes which are believed to dictate life itself.
These basic forms are agreed to determine art, architecture and design, for example, and, given its structure, it is fitting that the square is symbolised by four constituent parts: stability, strong foundations, order and the fixed nature of matter. It follows that grids and squares provide the framework within which sports and game-playing exists, from football pitches to tennis nets to checkerboards.
