true that all solid buildings, though not 

 equally immoveable, arc in themselves 

 equally motionless ; but where the surface 

 is even, the eye glides easily along it, and 

 that ideal motion of the sight, is in some 

 degree transferred to the object itself : all 

 easy 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 less 

 finely marked in the same book : 



■ . Under his burning wheels 



The steadfast empyrean shook throughout, 

 All but the throne itself of God.
