The 2300 years do not end before the year 2132 nor after 2370. The time times & half time do not end before 2060. .... It may end later, but I see no… - Isaac Newton

The ancients considered mechanics in a twofold respect; as rational, which proceeds accurately by demonstration, and practical. To practical mechanics all the manual arts belong, from which mechanics took its name. But as artificers do not work with perfect accuracy, it comes to pass that mechanics is so distinguished from geometry, that what is perfectly accurate is called geometrical; what is less so is called mechanical. But the errors are not in the art, but in the artificers. He that works with less accuracy is an imperfect mechanic: and if any could work with perfect accuracy, he would be the most perfect mechanic of all; for the description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geometry does not teach us to draw these lines, but requires them to be drawn; for it requires that the learner should first be taught to describe these accurately, before he enters upon geometry; then it shows how by these operations problems may be solved.

And now to explain colours. I suppose that as bodies excite sounds of various tones and consequently vibrations, in the air of various bignesses, so when rays of light by impinging on the stiff refracting superficies excite vibrations in the ether, these rays excite vibrations of various bignesses... therefore, the ends of the capillamenta of the optic nerve which front or face the retina being such refracting superficies, when the rays impinge on them they must there excite these vibrations, which vibrations (like those of sound in a trumpet) will run along the pores or crystalline pith of the capillamenta through the optic nerves into the sensorium (which light itself cannot do), and there, I suppose, affect the sense with various colours, according to their bigness and mixture—the biggest with the strongest colours, reds and yellows; the least with the weakest, blues and violets; middle with green; and a confusion of all with white, much after the manner, that in the sense of hearing, nature makes use of aereal vibrations of several bignesses to generate sounds of divers tones; for the analogy of nature is to be observed.

The Popes began also about this time to canonize saints, and to grant indulgences and pardons: and some represent that Leo III was the first author of all these things. It is further observable, that Charles the great, between the years 775 and 796, conquered all Germany from the Rhine and Danube northward to the Baltic sea, and eastward to the river Teis; extending his conquests also into Spain as far as the river Ebro: and by these conquests he laid the foundation of the new Empire; and at the same time propagated the Roman Catholic religion into all his conquests, obliging the Saxons and Huns who were heathens, to receive the Roman faith, and distributing his northern conquests into Bishoprics, granting tithes to the Clergy and Peter-pence to the Pope: by all which the Church of Rome was highly enlarged, enriched, exalted, and established.
