An ingenious writer has observed, that "a garden just accommodates itself to the perambulations of a scholar, who would perhaps rather wish his walks abridged than extended." There is a good characteristic account of the mode in which the Literati may take exercise, in Pope's Letters. "I, like a poor squirrel, am continually in motion indeed, but it is but a cage of three foot! my little excursions are like those of a shopkeeper, who walks every day a mile or two before his own door, but minds his business all the while." A turn or two in a garden will often very happily close a fine period, mature an unripened thought, and raise up fresh associations, whenever the mind, like the body, becomes rigid by preserving the same posture. Buffon often quitted the old tower he studied in, which was placed in the midst of his garden, for a walk in it. Evelyn loved "books and a garden." FOOTNOTES: [Footnote 21: The same anecdote is related of Dr. Johnson, who once being at a club where other literary men were indulging in jests, upon the entry of a new visitor exclaimed, "Let us be grave--here is a fool coming."] PORTRAITS OF AUTHORS. With the ancients, it was undoubtedly a custom to place the portraits of authors before their works. Martial's 186th epigram of his fourteenth book is a mere play on words, concerning a little volume containing the works of Virgil, and which had his portrait prefixed to it. The volume and the characters must have been very diminutive. _Quam brevis immensum cepit membrana Maronem! Ipsius Vultus prima tabella gerit._ Martial is not the only writer who takes notice of the ancients prefixing portraits to the works of authors. Seneca, in his ninth chapter on the Tranquillity of the Soul, complains of many of the luxurious great, who, like so many of our own collectors, possessed libraries as they did their estates and equipages. "It is melancholy to observe how the portraits of men of genius, and the works of their divine intelligence, are used only as the luxury and the ornaments of walls." Pliny has nearly the same observation, _lib._ xxxv. _cap._ 2. He remarks, that the custom was rather modern in his time; and attributes to Asinius Pollio the honour of having introduced it into Rome. "In consecrating a library with the portraits of our illustrious authors, he has formed, if I may so express myself, a republic of the intellectual powers of men." To the richness of book-treasures, Asinius Pollio had associated a new source of pleasure, by placing the statues of their authors amidst them, inspiring the minds of the spectators, even by their eyes.
