No one told me that the pyramids had been one of the seven wonders of the ancient world, but they were certainly the primal wonder of mine. From early on they exercised an oddly persistent fascination.They could not, it seemed, be taken for granted, like hills and trees and houses. Approached along the pyramid road they got larger and larger and larger until they filled up one half of the sky. It took a long while to ride lurchingly round the Great Pyramid on a camel, and from no angle could their stupendousness be made a thing of nought. They were made of square yellow blocks, exactly like sugar lumps, but higher than I was.
