The anguish of the third dimension is given its first verbal 
manifestation in poetic history in King Lear.

*     Shakespeare seems to have missed due recognition for 
having in King Lear  made the first, and so far as I know, the

that a fixed visual point of view is deliberately provided for the 
reader:

     Outshon the wealth of Ormus  and of Ind ,
     Or where the gorgeous East with richest hand 
     Showrs on her Kings Barbaric  Pearl and Gold, 
     Satan exalted sat, . . .
