The King, however, did not retain the volume for long, but exchanged it with the Earl of Pembroke for the beautiful little picture of “St. George slaying the Dragon,” by Raphael, which is now in the Hermitage Gallery, St. Petersburg. This latter is entered in Van der Doort’s catalogue as “A little St. George, which the King had in exchange of My Lord Chamberlain, Earl of Pembroke, for the book of Holbein’s drawings.” This picture was sold by the Commonwealth for £150, and after passing through the La Noue, De Sourdis, and Crozat collections, found a final resting-place in the Hermitage. In 1627, while still in the Earl of Pembroke’s possession, it was engraved by Lucas Vorsterman, so that the exchange with the King may have taken place in 1628 or thereabouts. Lord Pembroke, in his turn, did not keep the drawings, but almost at once passed them on to the great collector, Thomas Howard, Earl of Arundel, who, according to Sir Edward Walker, who wrote his life, had “more of that exquisite master, Hans Holbein, than are in the world besides.” Whether Lord Pembroke gave the drawings to him, or in his turn carried out a second exchange, is not known. Their presence in the Arundel Collection is proved by a contemporary reference in the manuscript among the Harleian MSS.[562] in the British Museum entitled, “An exact & Compendious Discours concerning the Art of Miniatura or Limning,” on the fly-leaf of which is written, in an eighteenth-century hand, “of Limning by Hilliard,” to which attention has been already called.[563] As the Holbein drawings were still in the possession of Charles I in 1627, the paragraph in the “discours” which speaks of them as in the Arundel Collection cannot have been penned by Nicholas Hilliard himself, who died in 1619. The compiler was almost certainly Edward Norgate, who held Holbein in the highest estimation. Speaking of the painting of shadows, he says:— Footnote 562: No. 6000. Footnote 563: See p. 219. “The black must be deepened with ivory black, and if in working in the heightenings and light-reflections, you will mingle with your ordinary black a little lake and indigo, or rather a little litmus instead of indigo, you will find your black to render a rare and admirable reflection like to that of the well-dyed satin, especially if your lights be strong and hard; the manner whereof if you please to see inimitably expressed, you will find abundantly for your content in the gallery of my most noble Lord the Earl of Arundell, Earl Marshal of England, and done by the incomparable pencil of that rare master, Hans Holbein, who in all his different and various manners of painting, either in oil, distemper, limning, or crayon, it seems was so general and absolute an artist, as never to imitate any man, or ever was worthily imitated by any.”[564] Footnote 564: Quoted by Wornum, pp. 397-8. Also by Dallaway with slight differences (see p. 219 above).
