true tliat all solid buildings, though not 

 equally immoveable, are in themselves 

 equally motionless ; but where the surface 

 is even, the eye glides easil}^ along it, and 

 that ideal motion of the sidit, is in some 

 degree transferred to the object itself: all 

 eas}^ transitions, therefore, from one ob- 

 ject, or from one part of an object to an- 

 other, which constitute so principal a cause 

 of beauty, are equally a cause of lightness ; 

 and it may be observed, that many of the 

 terms used on such occasions, are borrowed 

 from those of motion. To apply this to the 

 present subject I must observe, that where 

 the general surface of a bridge is even, and 

 where the projections and ornaments are 



Light as the lightning glimpse they ran, they flew. 

 From their foundations loos'ning to and fro, 

 THey pluck'd the seated hills with all their load, 

 Rocks, waters, woods, and by the shaggy tops 

 Uplifting, bore them in their hands. 



The grandeur arising from absolute immobility, is no, les» 



finely marked in the same book : 



■ Under his burning wheels 



The steadfast empyrean shook throughout, 

 AH but the throne itself of God.
