Erasmus had asked AEgidius to assist Holbein's success in any way he could. And it was probably owing to a letter from the Antwerp scholar that a friendship of many years sprang up between the painter and Nicholas Kratzer of Munich, then Astronomer-Royal at the Court of Henry VIII. It began with what was once a fine portrait. But the oil painting, now in the Louvre (Plate 23), has suffered such severe injuries as to be but a poor ghost of what it was originally. Only the composition, and the fidelity with which all his friend's scientific instruments are drawn attest Holbein. He never adds a detail for merely pictorial purposes; and never shuffles one that concerns the personality of a sitter. No biographer with his pen sets every straw to show the winds of character and circumstance more deliberately than does this historian with his brush. Something of Kratzer's shrewd wit,--for he was a "character"--can still be read in his half-destroyed picture. Years later we shall see the intimate friend of both him and his painter writing of the astronomer as a man "brim-full" of humour and fancy. And once, we may be sure, it sparkled in the eyes of Kratzer's portrait as brilliantly as in his own. Illustration: PLATE 23 NICHOLAS KRATZER _Oils. The Louvre_ In the Munich Gallery there is another portrait in oils which has undergone, if possible, still more atrocious treatment than Kratzer's; yet, like it, still keeps enough of its original charm to rivet attention in any company. This latter is one of the most striking of the half-dozen portraits of Sir Bryan Tuke, which all claim, with more or less of probability, to be paintings by Holbein. And certainly in the years when Sir Bryan was Treasurer of the King's Household it would be natural that the painter, whose salary he regularly disbursed, should gladly oblige him to his utmost. But the Munich portrait also shows a far deeper bond of interests than one of money. The undercurrent of their natures ran in a groove of more than common sympathy; and to an analyst, such as Holbein was, the reflections behind these inscrutable eyes were full of unusual attraction.
