[1] The translation, under the title _Eight Books of the Peloponnesian War, written by Thucydides the son of Olorus, interpreted with faith and diligence immediately out of the Greek by Thomas Hobbes, secretary to the late Earl of Devonshire_, appeared in 1628 (or 1629), after the death of the earl, to whom touching reference is made in the dedication. It reappeared in 1634, with the date of the dedication altered, as if then newly written. Though Hobbes claims to have performed his work "with much more diligence than elegance," his version is remarkable as a piece of English writing, but is by no means accurate. It fills vols. viii. and ix. in Molesworth's collection (11 vols., including index vol.) of Hobbes's _English Works_ (London, Bohn, 1839-1845). The volumes of this collection will here be cited as E. W. Molesworth's collection of the Latin _Opera philosophica_ (5 vols., 1839-1845) will be cited as _L.W._ The five hundred and odd Latin hexameters under the title _De mirabilibus Pecci_ (_L.W._ v. 323-340), giving an account of a short excursion from Chatsworth to view the seven wonders of the Derbyshire Peak, were written before 1628 (in 1626 or 1627), though not published till 1636. It was a New Year's present to his patron, who gave him L5 in return. A later edition, in 1678, included an English version by another hand. [2] Hobbes, in minor works dealing with physical questions (L.W. iv. 316; _E.W._ vii. 112), makes two incidental references to Bacon's writings, but never mentions Bacon as he mentions Galileo, Kepler, Harvey, and others (_De corpore_, ep. ded.), among the lights of the century. The word "Induction," which occurs in only three or four passages throughout all his works (and these again minor ones), is never used by him with the faintest reminiscence of the import assigned to it by Bacon; and, as will be seen, he had nothing but scorn for experimental work in physics. [3] The free English abstract of Aristotle's _Rhetoric_, published in 1681, after Hobbes's death, as _The Whole Art of Rhetoric_ (_E.W._ vi. 423-510), corresponds with a Latin version dictated to his young pupil. Among Hobbes's papers preserved at Hardwick, where he died, there remains the boy's dictation-book, interspersed with headings, examples, &c. in Hobbes's hand. [4] Among the Hardwick papers there is preserved a MS. copy of the work, under the title _Elementes of Law Naturall and Politique_, with the dedication to the earl of Newcastle, written in Hobbes's own hand, and dated May 9, 1640. This dedication was prefixed to the first thirteen chapters of the work when printed by themselves, under the title _Human Nature_ in 1650.
