Persian gardens, proportion, and Plato’s Timaeus
The classical Persian garden, the chahar bagh, is divided into four parts by water channels meeting at a centre. Visit the Fin Garden in Kashan or Bagh-e Eram in Shiraz and you feel the order before you understand it.
In the Timaeus, Plato's craftsman god shapes the world according to mathematical proportion, assigns regular solids to the elements (the tetrahedron to fire, the cube to earth, the octahedron to air, the icosahedron to water), and makes the cosmos as beautiful as possible.
As an architect, I wonder: is beauty really proportion? The Persian garden suggests it's something more: proportion plus shade, water sound, scent, the way you move through it. Plato would say those are mere sense pleasures. Would he be right?
