In 1757 he published "A Prose Translation of the Works of Horace." From this performance he could derive but little fame. He thought that such a translation could be useful to those who are desirous of acquiring or recovering a competent knowledge of the Latin tongue. The good or the evil of literal translations is yet a problem, and each side of the question has its advocates. Though our poet was engaged on the one hand in translating the Odes of Horace into prose, on the other he successfully translated Pope's Ode to St. Cecilia into Latin verse, and thereby obtained the notice of Mr. Pope, with whom a correspondence ensued, of which Mr. Smart was not a little vain. In what manner he lived for some time after this, we are not told; but Garrick, finding him in pecuniary distress, gave him the profits of a benefit at his theatre. In 1763, he published "A Song to David," in which there are some passages greatly to be admired, and which, Mr. Editor, as a man of taste, you have introduced to your readers; but there are some to be found of even more majestic animation; and it will surprise the reader when he is told that this piece was composed by him during his confinement; when he was debarred the use of pen, ink, and paper, and was obliged to indent his lines, with the end of a key, upon the wainscot. In the same year he published "Poems," and at the conclusion betrays that irritability and self-conceit which are frequently observed to precede, and generally to accompany, derangement of mind. In all these poems his imagination, although occasionally fine, went often into wild excesses, and evinced that his mind had never recovered its _sober_ tone. In his intervals of health and regularity, he still continued to write. His "Translation of the Psalms of David" afford a melancholy proof of want of judgment and decay of powers. We find him at length an inmate of the King's Bench prison. Here he died after a short illness, occasioned by a disorder in his liver, May 18th, 1770, leaving two daughters, who, with his widow, were long settled at Reading, and by their prudent management of the bookselling trade, transferred to them by Mr. John Newbery, were enabled to maintain a very respectable rank in life. Of his personal character, the following particulars yet remain to be added from the memoirs: "His piety was exemplary and fervent; it may not be uninteresting to the reader to be told, that Mr. Smart, in composing the religious poems, was frequently so impressed with the sentiment of devotion, as to write particular passages on his knees. He was friendly, affectionate, and liberal to excess; so as often to give that to others of which he was in the utmost want himself."
