1. Newton I., 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 Conduitt John (King's College, Cambridge, Keynes MS. 127 A5) reproduced by Whiteside D. 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.
2. Newton and the ‘Pipes of Pan’
3. Besides several of his theological and exegetical writings; cf. Harrison J., The library of Isaac Newton (Cambridge, 1978), 195, nos. 1109–16.
