Geometry was seen as a reflection of a divine and cosmic order and a lot of Renaissance study was focused both on trying to find geometric patterns in nature and then trying to recreate this codified order in architecture, art, town planning and gardens. Long successions of theologians from St Augustine onwards were convinced that numbers and proportions were divined and that a secret canon could be partially derived from Holy Scripture. Art and science were strongly linked and a study of proportion and the human figure created a framework for a classical order of perspective, proportion, symmetry, and geometric forms, circles and triangles. These forms have provided the underlying grid for the Hamilton Gardens example.
