The central disk of onyx represents the world, and the two sets of four roundels around it the four elements and four qualities unified by love, a symbol of the Great Chain of Being that bound the monarch to the lowliest subject and the highest angel under God, as in this fifteenth-century text:
"In this order, hot things are in harmony with cold, dry with moist, heavy with light, great with little, high with low. In this order, angel is set over angel, rank upon rank in the kingdom of heaven; man is set over man, beast over beast, bird over bird and fish over fish, on the earth, in the air and in the sea: so that there is no worm that crawls upon the ground, no bird that flies on high, no fish that swims in the depths, which the chain of this order does not bind in the most harmonious concord. Hell alone, inhabited by none but sinners, asserts its claim to escape the embraces of this order." (Sir John Fortescue, trans. On Nature, 1492.)There was a Latin inscription to accompany the Pavement which described the age of the world from beginning to end as 19,683 years - the lifespan of the macrocosm conceived as a living creature. However inaccurate this is in terms of modern cosmology, it was an attempt to make the Pavement an image of the whole of space-time. We lost our "Theory of Everything", and modern science has been trying to get it back ever since.
