_Luther's Portrait at Warwick Castle_ (No. 25. p. 400.).--The Portrait
by Holbein, in Warwick Castle, certainly erroneously stated to be that
of Luther, was, I believe, engraved as such in Knight's _Portrait
Gallery_, published by the Society for the Diffusion of Useful
Knowledge. I cannot find in any account of Helbein's works a mention of
a portrait of Luther by him.
