At some point in or shortly after 1607, the opening passage of Francis Bacon's earliest surviving philosophical work, Valerius Terminus of the interpretation of nature – the first version of what ultimately became Bacon's Instauratio magna – was copied into the natural philosophical notebook of Edmund Leigh (c. 1585–1658), a Bachelor of Arts at Brasenose College, Oxford. Whereas contemporary scribal copies of Bacon's political, religious, and legal writings are common, copies of his unpublished philosophical writings are rare, and tend only to be found in unique exemplars with a direct Baconian association. As such, the Valerius Terminus has hitherto only been known from a single manuscript, with corrections in Bacon's hand, that was first printed in 1734. The discovery of a ‘user’ copy in a student notebook is therefore significant for what it suggests about the circulation of Bacon's earliest philosophical ideas. This significance is enhanced by the fact that the new copy appears to record an early draft of Bacon's work.

I am grateful to Louis Caron for drawing my attention to Add. MS 102, to Mordechai Feingold for his invaluable improvements and corrections to this study, and to Elizabeth Boardman and Georgina Edwards of the Brasenose College Archives.

Farrington, Benjamin, The philosophy of Francis Bacon: an essay on its development from 1603 to 1609 (Liverpool, 1964), pp. 3844; Milner, Benjamin, ‘Francis Bacon: the theological foundations of Valerius Terminus’, Journal of the History of Ideas, 58 (1997), pp. 245–64; Gaukroger, Stephen, Francis Bacon and the transformation of early modern philosophy (Cambridge, 2001), pp. 77–8, 155–6; Harrison, Peter, The fall of man and the foundations of science (Cambridge, 2007), pp. 27, 169–73; Jalobeanu, Dana, ‘Bacon's brotherhood and its classical sources’, in Zittel, C. et al. , eds., Philosophies of technology: Francis Bacon and his contempories (Leiden, 2008), pp. 197230; Georgescu, Laura, ‘Francis Bacon: the theological foundations of natural philosophy’, Studii de Ştiinţa şi Cultură, 23 (2010), pp. 7487; 22Lewis, Rhodri, ‘Francis Bacon, allegory and the uses of myth’, Review of English Studies, 61 (2010), pp. 360–89; Hartmann, Anna-Maria, ‘Light from darkness: the relationship between Francis Bacon's prima philosophia and his concept of the Greek fable’, Seventeenth Century, 26 (2011), pp. 203–20; Corneanu, Sorana, Regimens of the mind: Boyle, Locke, and the early modern cultura animi tradition (Chicago, IL, 2012), pp. 26–9, 34–7.

9 I am not aware that James Spedding's characteristically careful and perceptive discussion of the date of Valerius Terminus has yet been superseded (Bacon, Works, iii, pp. 206–13).

10 The exception to this generalization is the abandoned English treatise Filum labyrinthi siue formula inquisitionis (BL, MS Harley 6797, fos. 139r–146v; Bacon, Works, iii, pp. 496–504), effectively a translation of the opening portion of the Latin Cogitata et visa.

11 The full title also promises annotations by a different fictional persona, ‘Hermes Stella’, but as Bacon himself noted: ‘None of the Annotations of Stella are sett down in these fragments’ (BL, MS Harley 6463, fo. 1*v).

12 A list of the writings Bacon addressed directly to James in the aftermath of his accession would include: A brief discourse touching the happie union of the kingdomes (1603); Certaine considerations touching the better pacification and edification of the Church of England (composed, 1603; published illicitly, 1604); Of the proficience and advancement of learning (1605); ‘Of the true greatnes of the kingdome of Brittaine’ (c. 1607?); ‘Certain considerations touching the plantation in Ireland’ (1609).

13 BL, MS Harley 6463, pp. 1–70.

15 Stephens, Robert, ed., Letters and remains of the Lord Chancellor Bacon (London, 1734), pp. 398450; see also p. vii. Modern editions of the Valerius Terminus include the German translation by Franz Träger (Würzburg, 1984) and the French translation by François Vert (Paris, 1986).

16 Peter Beal, Catalogue of English literary manuscripts (CELM), unpublished database at (consulted July 2009). I am grateful to Dr Beal for granting me pre-publication access to his remarkable catalogue, which expands upon his earlier Index of English literary manuscripts, i: 1450–1625, Part i: Andrewes–Donne (London, 1980), pp. 17–52 (IELM); the Harleian MS of Valerius Terminus is item *BcF 285 in both.

17 Evidence for this circulation is extensively documented in IELM/CELM.

18 Francis Bacon, Scripta in naturali et universali philosophia, ed. Isaac Gruter (Amsterdam, 1653). See further Graham Rees, ‘Introduction’, to Graham Rees, ed., The Oxford Francis Bacon, vi: Philosophical studies, c. 1611–c. 1619 (Oxford, 1996), pp. lxx–lxxxv.

20 Bacon, Scripta in naturali et universali philosophia, sig. x2v: ‘intra legitima & optata ingenia clausa’.

21 Spedding, James, Letters and life of Francis Bacon (7 vols., London, 1861–74), iv, p. 64.

22 Ibid., iii, pp. 363–6, iv, p. 141, iii, p. 256.

23 See ibid., iii, p. 256, iv, pp. 132–3, 135–6, 137, 139.

24 Ibid., iv, pp. 8–9.

25 This copy was identified by the author in October 2012. The provenance of the manuscript remains uncertain: A catalogue of the manuscripts preserved in the library of the University of Cambridge (5 vols., Cambridge, 1856–67), v, p. 569, merely describes the early Additional Manuscripts as those ‘which have previously had no shelf-mark’.

26 Feingold, Mathematician's apprenticeship, p. 100; Feingold, Mordechai, ‘The occult tradition in English universities of the Renaissance: a reassessment’, in Vickers, B., ed., Occult and scientific mentalities in the Renaissance (Cambridge, 1984), pp. 7394, at p. 78.

27 For this reason it is difficult to be absolutely confident that the copy of the Valerius Terminus was made by the same scribe as the one whose hand is found elsewhere throughout the volume.

28 Presentation manuscripts of some of Bacon's writings also exist with this mixture of humanist minuscule titles and formal italic text, although none is in the same hand as this one. See Queen's College, Oxford, MS 280, pp. 205–33 (‘Cogitata et visa’, c. 1607); and Huntington Library, San Marino, MS EL 1721, and National Library of Ireland, MS 2582 (‘Certaine considerations touching the plantation in Ireland’, 1609).

29 In establishing this list on the basis of the author's rather cryptic references I have benefited from the fine new Universal short-title catalogue: Dates are of first publication, which is not necessarily the edition that was being read.

30 See the parallel instance of the notebook kept by the MA student George Palfrey at Sidney Sussex College, Cambridge, in the earlier 1620s (Cook, C. J., ed., The Palfrey notebook: records of study in seventeenth-century Cambridge (Woodbridge, 2011)); the students share an interest in Franciscus Toletus's Commentarius de anima.

31 On the structure of disputations see Costello, Scholastic curriculum, pp. 14–31. Cook, ed., The Palfrey notebook, pp. 138–40, 150–2, also records disputations, though in a more telegraphic fashion.

33 Nichols, John, The progresses … of King James the first (4 vols., London, 1828), i, pp. 536–7. It should be noted that the thesis ‘Imaginatio producit reales effectus’ was also disputed at the philosophy tripos in Cambridge in 1609; see Hall, J. J., Cambridge Act and Tripos verses, 1565–1894 (Cambridge, 2009), p. 134.

34 On this kind of neo-classical debate on laughter, see Skinner, Quentin, ‘Why laughing mattered in the Renaissance’, History of Political Thought, 22 (2001), pp. 418–47.

36 See further Feingold, Mathematician's apprenticeship, p. 100.

37 The very few other appearances of the English language in the manuscript are fragmentary in nature: see the front paste-down (not, I think, in the hand of the main scribe); fo. 236r; and the penultimate leaf, fo. 293v.

42 Quotation from Spedding, Letters and life, i, p. 109 (Bacon to Lord Burghley, n.d., c. 1592).

43 In fact the ‘e’ in the surname of the signature is both caudate (indicating the dipthong æ) and carries a dieresis (indicating that the two syllables should be pronounced separately), but it has not proved typographically possible to represent this here.

44 The online manuscript catalogue of the CUL, Janus (, consulted Oct. 2012), assigns the volume to an ‘Edmund Lee’; as we shall see, however, this is not quite correct.

B., ‘Sir Thomas Egerton as patron’, Huntington Library Quarterly, 11 (1948), pp. 105–27 (pp. 124–7), identifies six members of Brasenose. Leigh also entered Brasenose at the same time as a young Cheshire gentleman also named Thomas Egerton (Clark, Register, p. 242) who, though not a descendant, may have been a kinsman of the lord chancellor.
