Stripped of the fashions of his day, sat bleakly against a plain blue wall, Johannes Froben doesn’t look like a sixteenth-century printer. In Hans Holbein’s portrait, he could be anyone, at any time. He looks to his left, his hair thinning, his cheeks sagging, his skin sallow, his arms tucket miserably into his black coat. It’s so stark, so quiet, so rueful and heavy with years of worry and effort. Holbein was special.
