ABSTRACT
We all know that you can't count on eyes. Eyes go wrong, unaccountably. Yet in Egypt over five thousand years ago there was an eye you could count with: the eye of Horus. The god Horus, represented as a man with the head of a falcon, was the earliest of the Egyptian gods, worshipped predynastically as the face of the sky, his eyes being the sun and the moon. When neither sun nor moon was visible the sky was called 'Horus dwelling without eyes'.
