says Heeren in his Researches on the Ethiopians, “determined very naturally the principal character of the Nubian Egyptian architecture to the colossal form which it assumed. In these caverns, already prepared by nature, the eye was accustomed to dwell on huge shapes and masses, so that when art came to the assistance of nature it could not move on a small scale without degrading itself. What would statues of the usual size, or neat porches and wings have been, associated with those gigantic halls before which only Colossi could sit as watchmen or lean on the pillars of the interior?”

The Gothic church plainly originated in a rude adaptation of the forest trees, with all their boughs, to a festal or solemn arcade; as the bands about the cleft pillars still indicate the green withes that tied them.
