The first Primary Light is that which falleth upon and is receiv’d in that Part of a Colour’d Body which is opposite to the Body giving Light ; which running upon the Bodys, toucheth them sweetly with a certain Natural Order, not possessing them in any of the Extreams as other Lights do, and must be observ’d in Historys suppos’d in the open Air.
The Second Primary Light is that which is caus’d by the Apparitions of Angels, or Glory, as about our Saviour in his Nativity, his Transfiguration, his Resurrection, &c. and it must be observ’d in all parts according to their distance on every side.
The third Primary Light is from Fire, Torches, Lamps, Candles, &c. but must be less Refulgient then the last. In this we must observe whither it be by Day or Night, the Matter Burning, &c.
Where there be several Lights there must be care taken how they are placed that by their Opposition, they take not away all Occasions of Shaddowing, which will diminish their Beauty, though the want of force and strength ; likewise that they cast not double Shaddows, and confound each other.
