The doctor's face blazed: his bent figure seemed to straighten itself and become taller.

"Ah," he cried, growing more dithyrambic, "how lightly you ask what it means! How confidently you expect an answer! Yet here am I who have given my life to the study of the Renaissance; who have violated its tomb, laid open its dead body, and traced the course of every muscle, bone, and artery; who have sucked its very soul from the pages of poets and humanists; who have wept and believed with Joachim of Flora, smiled and doubted with AEneas Sylvius Piccolomini; who have patiently followed to its source the least inspiration of the masters, and groped in neolithic caverns and Babylonian ruins for the first unfolding tendrils of the arabesques of Mantegna and Crivelli; and I tell you that I stand abashed and ignorant before the mystery of this picture. It means nothing -- it means all things. It may represent the period which saw its creation; it may represent all ages past and to come. There are volumes of meaning in the tiniest emblem on the lady's cloak; the blossoms of its border are rooted in the deepest soil of myth and tradition. Don't ask what it means, young man, but bow your head in thankfulness for having seen it!"

He answered with a despairing gesture. "Ah, it's easy for you to talk. You have years and years to spend with it; I am an old man, and every moment counts!"

"It's bad for you," she repeated with gentle obstinacy.
