Alas ! how loft thofe magic mixtures all ! 355 

 No hues of his now animate the wall ; 

 How then fliall modern Art thofe hues apply, 

 How give Defign its finim'd dignity ? 

 Return fair COLORING ! all thy lures prepare, 

 Each fafe deception, every honeft fnare, 360 



Which brings new lovers to thy lifter's train, 

 Skilful at once to charm, and to retain ; 

 Come faithful Siren ! chaft feducer ! fay, 

 What laws control thee, and what powers obey. 



Know firft that Light difplays and fhade deftroys 

 Refulgent Nature's variegated dyes. 



Thus bodies near the light diftinctly fhine 

 With rays direct, and as it fades decline. 



Haec quidem ut in tabulis fallax, fed grata venuftas, 



Et complementum graphidos, inirabile vifu, 



Pulchra vocabatur, fed fubdola, lena fororis : 



Non tamen hoc lenocinium, fucufque, dolufque 



Dedecori fuit unquam ; illi fed femper honor^ 265 



Laudibus & mentis -, hanc ergo nofie juvabit. 



Lux variqm, vivumque dabit, nullum umbra, colorem. 



Quo magis adverfum eft corpus, lucique propinquum ? 

 Clarius eft lumen ; nam debilitatur eundo.
