IV in one passage. A similar diagram to ours is to be found in the Preface to Kepler's Mysterium Cosmographicum, (ed. Ch. Frisch, Vol. I, Frankfurt, ; ed. F. Hammer, Vol. VIII, Munich 1963, p. 26) of 1621. Kepler tells us that he was lecturing with this diagram on 9 or 19 July 1595 when he was led by it to a scheme of cosmic harmony. The diagram is not to be found in Albumasar, and is included here for purely explanatory purposes. Kepler's parameters differed somewhat from Albumasar's. Although I have not yet introduced Kepler's terminology, for which see n.19 below, this is a suitable place at which to point out that he half‐heartedly believed in a correlation of ‘maximum conjunctions’ and historical periods. The epochs which are apparently implied there are 3975 B.C. (or Creation), 3182 B.C. (Enoch), 2388 B.C. (Noah), 1514 B.C. [Truncated]

According to Hipparchus the stars change their celestial longitudes at a rate of ‘at least’ one degree per century. Ptolemy, in Almagest, repeated the argument but later took the figure to be exact. The stars should accordingly make a circuit of the sky in 360 times 100 years. This has nothing to do with the planetary motions with which we are concerned.

h (minores). Rheinhold gave periods close to Cardan's. Kepler (see n. 11 above) rounded off to 794 years for the coniunctio maxima, made no mention of con. media, and loosely defined coniunctio magna as a conjunction of Saturn and Jupiter with Mars nearby.

Dicamus quoque quia cum Juppiter per naturam significet fidem et diversitatem legum in temporibus et vicibus atque sectis ex complexionibus Saturni et ex complectionibus ceterorum planetarum cum eo scilicet Jove… Si fuerit complexus Saturnus, significabit quod fides civium eiusdem sit Judaisma, quod congruit planete Saturni eo quod omnes planete iunguntur ei, et ipse nemici illorum iungitur. Et similiter iudaica fides; omnes cives ceterarum confitentur ei; et ipsa nulli confitetur… Et si complexus ei fuerit Mars significat culturam igneam et fidem paganam. Et si complexa ei fuerit Venus significat fidem unitatis et mundam, ut fidem Saracenorum et ei similem. Et si complexus ei fuerit Mercurius significat fidem Christianam… Et si complexa fuerit ei Luna significat dubitationem ac volutionem et mutationem ac expoliationem a fide… (Albumasar, De magnis coniunctionibus, II. 8; quoted from Garin, ed. cit., n. 90 below).

Ibid.,. pseudo‐Zoroastrian work is entitled Liber de dominio quartarum octave spere. A quadrant of the eighth sphere is said to dominate every historical period of 12,000 years and the turning points of which men of divine attributes are born of incubi and succubi, etc. etc. This has more the appearance of an Indo‐Persian doctrine than of anything based on a theory of the precession of the eighth sphere

The Summa was printed at Venice in 1489. The Bodleian copy (Ashmole 576) is much corrected at the outset from a Merton manuscript, probably now MS Oriel 23. The author's name is rendered ‘Eschuid’ in the printed edition. The copy in the Kongelige Bibliotek, Copenhagen, is sparsely annotated, and then chiefly in the sections on great conjunctions.

The best MS., namely Digby 176, belonged to Reed, who assembled it piecemeal in an interesting way, explained in a note on f. 1 v; and in a table of contents on the same page the two statements are made about the authorship of the calculations. There is, even so, room for doubt. I have recalculated all the conjunctions in the table (n. 50), and found that (I) the first for 1349 is very close indeed to a prediction on the basis of the Alfonsine tables; but five days out by the Toledan tables; (II) the second for 1349 would have been predicted for (the correct) 6 August from both tables; (III) the other two were badly calculated, but in both cases the results quoted come appreciably nearer to Alfonsine predictions; (IV) for 1345, the Alfonsine prediction would have been for 17 March, the Toledan for more than 3 weeks earlier, the actual conjunction March 24, and the quoted conjunction March 23, which therefore has an ex post facto look about it. The agreement may simply be a fortunate chance. These figures may also have been covertly borrowed (see n. 53 below). The precise prediction of a conjunction along traditional lines is a tedious business, with ample room for mistakes.

A French translation of a large part of this letter is given by Pierre Duhem, Le Système du Monde, Vol. IV Paris, repr., pp. 35–7, although as Thorndike indicates (op. cit., Vol. III, p., n. 81), Duhem's interpretation is vitiated by the fact that he misread the symbols for Jupiter and Saturn, and interchanged meanings. (From a French standpoint, the worst mistake was to have made France subject to Saturn and England to Jupiter. Duhem, who was intensely nationalistic, probably never made a more sinister error.) Jean predicted the conjunction for 30 October 1365 in 8° Scorpio, and the later Ashenden/Reed figures were in suspicious agreement with these. Both figures are in error (25 October, 7° Scorpio), but presumably because based on the same (Alfonsine) tables. Note that the Chronica Johannis de Reading, ed. J. Tait (Manchester, 1914), p. 166, the conjunction as having happened on 30 October in 8° Scorpio. One must obviously treat chronicles with caution, [Truncated]

The strongly Aristotelian second part is an interesting piece of natural philosophy, discussing as it does properly physical influences (like magnetic influence) as possibly radiating from the stars. It ends with the admission: ‘Nolo tamen negare, quin sint in superioribus multe habitudines causales et inclinative inferiorum ad diversas dispositiones et effectus, ex quibus habitudinibus, si constarent simul, et ex dispositione inferiorum possent aliqui effectus futuri propinqui pronosticari et rationabiliteter coniecturari’, II.
