¶Of Ethere shining. Chap. 5.
EThere in Gréeke is shining, and Isi∣dore saith. The ouer parts of fire, & of aire are called Ether, where is euer∣lasting shining of lyght and of bright∣nesse. And Anaxagoras saith, that that name Ether, is the name of fire. And as Aristotle sayth, he troweth that, for the burning, which commeth of the swifte∣nesse of the mouing thereof: and so A∣naxagoras meaneth, that all thing which burneth is called by that name Ether. And Alarcianu• saith, that Ether is the place, which is departed from the nether worlde, and is vnséene in comparison to yt nether, which suffereth many manner diuersitie and chaunging. For in Ethe∣re, in that place is day euerlasting, no night commeth after day light, and no wonder: for the shadowe of the earth, which is cause of the night, commeth not in so high a place, as is that place, which is called Ether, as in li. Metheo∣rorum Arist saith, that Ether is nought els in kinde, but one element, & is none of the foure Elements: For all thing which is aboue ye roundnes of ye Moone, is of kinde departed from the kinde of the nether elements. Therfore Ether is neither heauie nor light, nor thinne nor thick: nor may be departed by thirling & holing of another bodie. For no corrup∣tion nor alteration may come and enter into the kind which is called Ether, nei∣ther into all nor into part thereof: and if it came, as had composition of the E∣lements, then corruption shoulde come therein. But yet Anaxagoras saith, that Ether is the aire, which is set a fire. And he saith, that sometime it cōmeth down∣ward, and is hid within the earth: and for the subtiltie thereof, it is ruled now vpward, now downward: and therfore commeth earth shaking, of the vertue of Ether closed in the inner partes of the earth. But Aristotle sayth, that this sai∣eng is erronious: For a subtill thing moueth not downward: and also though it moued downwarde, yet it should not make such working. And as Macrobi∣us sayth, The shining of Ether vnder the roundnesse of heauen, blaseth and shineth into all the roundnesse of the worlde: and contayneth in it selfe the roundnesse of the seuen Planets, which moue agaynst the mooing of the Fir∣mament. And the neather parte of the Page 123 aire with swiftnesse of his mouing, set∣teth on fire the ouer part of matters E∣lementall: and of that setting on fire, the roundnesse of fire is gendred and bred, as it is sayd, in libro de coelo & mun∣do in sine. And Ether is not set on fire, by the matter that is so set on fire. For it taketh no chaunging of the neather things, though those neather things take chaunging thereof.
