performances had begun. Below him, indeed, on the arena from which he
had not once raised his eyes, nothing was to be seen on the yellow sand
but the scented fountain and a shapeless body, by which a second and a
third were soon lying; but overhead something was astir, and, from the
right-hand side, bright rays flashed across the wide space. Above the
vast circle of seats, arranged on seven tiers, suns and huge, strangely
shaped stars were seen, which shed a subdued, many-tinted radiance; and

He perceived, with amazement, that the givers of the entertainment, in
their anxiety to set something absolutely new before their imperial

fighting with the energy of despair. The Egyptian myth of the gods of
the great lights who sail the celestial ocean in golden barks, and of the
sun-god who each morning conquers the demons of darkness, had suggested
