" His personal fulfillment did not lead him to evolve a cheerful Madonna; on the contrary this Madonna was sad; she had already, through his sculptures, known the Descent. The tranquility of his early bas-relief, when Mary still had her decision to make, could never be recaptured. This young mother was committed; she knew the end of her boy’s life. That was why she was reluctant to let him go, this beautiful, husky,healthy boy, his hand clasped for protection in hers. That
was why she sheltered him with the side of her cloak.
The child, sensitive to his mother’s mood, had a touch of melancholy about the eyes. He was strong, he had courage, he would step forth from the safe harbor of his mother’s lap, but just now he gripped her hand with the fingers of one hand, and with the
other held securely to her side. Or was it his own mother he was thinking about, sad because she must leave her son alone in the world? Himself, who clung to her? "
