At each of its six angles stand saints, evangelists, and angels, whose symbolism it is not now so easy to decipher.

The most beautiful groups are a company of angels blowing the judgment trumpets, and a winged youth standing above a winged lion and bull.

These groups separate the several compartments of the bas-reliefs, and help to form the body of the pulpit.

Beneath, on capital's of the supporting pillars, stand the Sibyls, each with her attendant genius, while prophets lean or crouch within the spandrils of the arches.

Thus every portion of this master-work is crowded with figures--some detached, some executed in relief; and yet, amid so great a multitude, the eye is not confused; the total effect is nowhere dissipated.
