_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. S.W. _Symbolism of Flowers, etc._--In reference to works illustrative of poetical, mythological, scriptural, and historical associations connected with animals and plants, inquired for in No. 11. p. 173., many a literary man must equally desire an interpreter,-- "T' unbind the charms that in slight fables lie, And teach that truth is truest poesy." Yet, in the English language there is, I believe, no work of this description; and I therefore beg leave to suggest, that your learned correspondents may contribute to a very useful compilation by furnishing illustrations, or references to illustrations, critical and poetical, collected from the most valuable authors, ancient and modern; and that this "sacred eloquence," {458} "Where'er 'tis found On Christian or on heathen ground," if transplanted into learned pages, would to many readers, afford much pleasure. Meanwhile, I would refer Querist to the useful work of Camerarius on _Symbols and Emblems_. "Do thou, bright Phoebus, guide me luckily To the first plant by some kind augury." The proverbial expression, "Under the rose," appears opportunely in p. 214, beautifully illustrated[4], but still deserving further consideration. Schedius (_De Diis Gemanis_) and others have, with much learning, shown Venus Urania to be the same as Isis Myrionyma. With erudition not inferior, but in support of a peculiar theory, Gorop. Bacanus maintains Harpocrates and Cupido, son of Venus Uranis, to be one and the same hieroglyphical character. I shall now endeavour to explain the symbolism and dedication of the Rose. This "flower of flowers" adumbrates the highest faculty of human nature--_Reason_, and Silence, or the rest of the reasoning powers, which is indicated by the Greek term [Greek: epistaemae], _science_. (See Harris's _Philosoph. Arrang._ p. 444., and _Hermes_, p. 369.). To whom, then, could the hieroglyphical rose have been more appropriately dedicated than Harpocrates, who is described with his finger pointing to his mouth--_tacito plenus amore_--a proper emblem of that silence with which we ought to behave in religious matters. T.J. [Footnote 4: Has "ARCHILAEUS" looked for these verses into the _Rhodologia_ of Rosenbergius? I have in vain searched for them under "Rosæ," in the _Amphitheatrum sapientiæ_ of Dornavius.]
