De Materia coloris. cap. 2.

A Cléere thing well termined, is the matter of colour, and that onelye or namely thing that is moyst: for drye & earthie is not cléere, insomuch as it is drye: and fierie drought commeth not downe from his sphere and place of the fire, nor is found héere beneath among vs: for onely forme of fire, is gendered of might of some element, of the which a medled body shall be made, as it it sayd in li. de generatione. Then such a cléere∣nesse hath thrée materiall diuersities, for the matter is thin, or thicke, or meane: If it be meane, then there is much more moisture of water than drines of earth, & passing ye moisture of aire failing from ye airie moysture. Or els it is airy much chaunged by the thing that is dry & ear∣thie, yet so that it passeth grosenes. And if it be thin and small, then it is moyst & changeth to the matter of aire, or els it is moyst & airie, & changeth to thicknesse and drines of earth, so that it passeth not & goeth not beyond meannesse of earth.
