 ents, which go very near to prove, that this 

 branch of painting was underftood among them:

 tranflated than by the/cience of light and ihade. 



Among the enumeration of paintings, by va-

 Echion, Anus lampadas preferens. Antiphilus, 

 Puero ignem conflante laudatus^ ac pulchrd alias domo 

 fplendefcentCy ipfmjque pueri ora. Philifcus, Off.ci- 

 nam p5ioriSy ignem conflante puero. f
