NewtonI., De mundi systemate (London, 1728). The work was sold to the booksellers Tonson, Osborn & Longman by the administrators of Newton's intestate estate for £31.10s; see the memoir by ConduittJohn (King's College, Cambridge, Keynes MS. 127 A5) reproduced by WhitesideD. T. in The mathematical papers of Isaac Newton, i (Cambridge, 1967), xviii–xx. Numa Pompilius and the Temple of Vesta as a symbol for the heliocentric universe are a quotation from Plutarch, as Newton has taken the trouble to note in the margin. Indeed, one reads in the life of Numa: “Ferunt Numam aedem quoque Vestae sacro igni orbicularem circumjecisse, ut ibi asservaretur, adumbrans non effigiem terrae, quasi ea Vesta sit, sed universi mundi, cujus in medio ignis sedem locant Pythagorici, eamque vestam nominant & unitatem.” Newton consulted a Latin edition of Plutarch, Opera (see note 3 below, p. 38); the passage is at vol. i, col. 67a. Newton returns to the symbolic circular temple at the end of Scholium IX; cf. note 50 below.

Speaking of the hypothesis of the aether: “And for rejecting such a medium, we have the authority of those the oldest and most celebrated Philosophers of Greece and Phoenicia, who made a vacuum, and Atoms, and the gravity of Atoms, the first principles of their Philosophy, tacitly attributing gravity to some other cause than dense matter” (Opticks, Query 28 (20 in the first edition, 1704), third edn (1721), 343–4?; Dover reprint (1952), 369).

The thesis of McGuire and Rattansi has indeed found a pretty favourable echo among the students of this current of thought, who have still further isolated it from its cultural context from the end of the sixteenth to the beginning of the eighteenth centuries. See SchmittCharles B., “Prisca Theologia e Philosophia Perennis: Due temi del Rinascimento italianoe la loro fortuna”, in Il pensiero italiano del rinascimento e il tempo nostro, Atti del V Convegno internazionale del Centro di Studi Umanistici, Montepulciano, 8–13 agosto 1968, 211–63; idem, “Perennial Philosophy from Agostino Steuco to Leibniz”, Journal of the history of ideas, xxvii (1966), 505–32; and WalkerD.

McGuireRattansi, op. cit. (ref. 5), 142, note 71: “These sources cannot be discussed in any detail here, although the historical sketch of the prisca doctrines in the text should help to clarify the significance of some of these citations”; as will be seen, a procedure has been chosen which is inverse to the correct one, by which a text is only to be interpreted historically after an analysis has been made of its internal stratification.

The image is in the Scholium to Prop. IX (see below, note 46, p. 44); a variant is the other image of the Lyre of Apollo which Newton cites in the Scholium to Prop. VIII from passages in Pliny and Macrobius (cf. notes 35 and 36). In the Queries in Opticks, composed later, Newton quotes both the images without naming the sources for them.

“Fistula enim ex septem calamis concentum rerum et harmoniam, sive concordiam cum discordia mixtam, quae ex septem stellarum errantium mota conficitur, evidenter ostendit” (BaconF., De sapientia veterum, in Works, ed. by Ellis, Spedding and Heath (London, 1887–92), vi, 638). Newton possessed the Essays (1706) and the Opuscula varia (1658) of Bacon; among the Essays present was the Discourse on the wisdom of the Ancients (cf. Harrison, op. cit. (ref. 10), nos. 108–9). It is certain that Bacon too was greatly indebted to Natale Conti, see RossiP., Francesco Bacone, della magia alla scienza (Bar, 1957), 206ff. (English trans. (1968), 78, 93, 255).

Besides the book by Dobbs, one should consult the earlier studies by WestfallR. S., “Newton and the Hermetic tradition”, in Science, medicine and society in the Renaissance: Essays to honor Walter Pagel, ed. by DebusA. G. (New York, 1972), ii, 183–98; “The role of alchemy in Newton's career”, in Reason, experiment and mysticism in the Scientific Revolution, ed. by BonelliM. L. RighiniSheaW. R. (New York, 1975), 199–232 (with commentaries by CasiniP.HallM. Boas). Westfall first disclosed his researches into the Hermetic Key in the large volume Force in Newton's physics (London, 1971). It is interesting to note that one of the authors of “Newton and the Pipes of Pan”, McGuireJ. E., has in a recent essay proposed a sharp discrimination between the ‘Platonism’ that Newton shares with the Cambridge Platonists, and the ‘Hermeticism’ which he, McGuire, rejects: “There is no evidence that Hermetic magic appealed to Newton…. Nor does Newton make any significant references to Hernies in his writings. Where he does, ‘Hermetic'is a stock phrase referring to alchemy and cannot be pressed unduly. The materials he gathered in the 1690s for inclusion in the opening proposition of the third book of the Principia [the classical Scholia] do not make mention of Hermes or of Hermeticism, although they refer to the opinions of many of the Neoplatonists” (“Neoplatonism and active principles: Newton and the Corpus Hermeticum”, in Hermeticism and the Scientific Revolution (William Andrews Clark Memorial Library, Los Angeles, 1977), 131). This is a distinction one may well accept, against the thesis of Westfall and Dobbs.

(ref. 33), 130: “…it cannot be concluded that Newton perceived himself as a mere renovator of lost wisdom…. The problems that Newton conceived and tackled in his science were not set by the parameters of ancient thought, nor did ancient thought function as a direct source for his creative ideas. The enterprise of interpreting ancient thought could only commence for Newton after the techniques of seventeenth-century science had revealed anew the real structure of things.”.

In his edition of the Principia, “with variant readings” (Cambridge, 1972), ii, 803–7, I. Bernard Cohen has confined himself to a transcription of the autograph leaf by Newton that is folded in four and inserted between pages 412 and 413 of a copy of the Principia (1687), once Newton's property and now in Cambridge University Library, pressmarked Adv. b. 39.1. No one knows how this leaf came there; it was surely not inserted there by Newton himself (who, if he had done so, would have added all the classical Scholia); probably it was done by some ill-informed custodian of the book. Cohen does not transcribe the texts in the correct order, nor indicate the sources of them.
