Of coulours perticular. chap. 14.

NOw it followeth to speake of per∣ticular colours, and first of white, that is the chiefe fundament and ground of meane colours. Whitenes is a colour gendered of much cléere light, and pure matter & cléere, as Algasel saith. And so the more pure the cléere matter is, & the more cléere ye light is, the more white the colour is, & the lesse medled with black, then ye materiall cause of white colour is cléere & pure, without medling of earthy drafts, now dry & now moist. The cause of working & making white coulour is cold or heat, for if drinesse hath the ma∣stry in working therin, thē white colour is gendered, for thinning and subtilling of partes of the matter, and for cléering by vertue of might and heat, as it fareth in Lime and in burnt bones. And if the matter be moyst in substance, and colde hath mastrye in working therein, then white colour is gendered, as it fareth in snow & in dew. Therfore white is gen∣dred of aire that is some deale watry, as Aristotle sayth, lib. 19. de Animalibus, and that by working of colde, for colde maketh moyst matter white, and drye matter blacke. Also white matter is gen∣dered of chinning and spreading of ayre, as it fareth in skumme: and therfore hot water gendereth white haire, and a hot braine is cause of baldnesse, for white commeth not but of vapourable aire and watry that is in the members. And for white commeth of hot ayre and vapou∣rable, therfore beasts be white vnder the wombe, as Ari. saith, li. 19. de Animali∣bus. White hath vertue to shed the sight, & to shed ye visible spirit if it be too white, and maketh the eie watry and to drop, and is the ground of all coulours, & the meane colours bée grounded in no other coulour better then in white. And the more white the ground is, the faster the coulour cleaueth and abideth, that is lai∣ed therevppon, whether it bée white or black and to whitenesse belongeth & ap∣perteineth Candor, Albor, Palior, Li∣uor, or Flauor. In one meaning Flauum & Liuidum is all one, as Aristotle sayth in cap. de. Sapore. And he sayth, ye Liui∣dum is Flauum, for hée followeth the kinde of white. Phisitions doe assigne many other maner colours about white, as watrie colour, and milkie colour, and Karapos, that is whitish or palish, and be diuers as the matter is diuerse, in which they be rotted, thick or thinne, as it is sayd in libro de Isaac, Theophile, Constantine, Egid. de vrinis, Candor, is passing whitenesse, and hath in it selfe much light in forme, and much pure∣nesse & cléerenesse in matter, for blasing of brightnesse, ye dresseth matter that is without, that is cléere & pure & printeth likenesse in the sight, without gréening of the eye, & comforteth the sight to be∣hold theron with a manner liking: such whitenes is called Candor, yt is first séene of whitnesse, by doing of lyght, with∣out corruption of the sight, and is called Candor, for the vttermost whitenesse is not séene with eie, for it voideth ye dome of sight, for nothing may be séene vnder the vttermost coulour: For the vtter∣most colours be vnseene by themselues, for cleerenesse thereof, as it is said in li. de Sensu & Sensato. cap. octauo. Then that that is first séene of whitenesse is tearmed Candor.
