 finished look than an}' other part ; a very 

 material circumstance in whatever is to be 

 combined with the highly-finished forms and 

 ornaments of architecture. It remains to 

 be considered, by what means these defects 

 may be diminished. Few roofs of ancient 

 buildings remain ; in them, however, a pe- 

 culiar attention seems to have been paid 

 both to regularity of construction, and to 

 lioht and shadow. The Tower of the Winds 

 at Athens is covered with slabs of marble, 

 in each of which the horizontal edge pro- 

 jects so much, as to give a strong shade ; 

 while the vertical joints are so elevated as to 

 fonn high ribs, which break the uniform 

 surface in a very beautiful manner.* The 

 Lanthorn of Demosthenes is roofed in the 

 form of laurel leaves, which, in a different
