Last night I was reading Finnegans Wake pages 492 to 505. I thought at once of writing to Giedion about it. In these pages Joyce runs through the letters of the alphabet from A to Z as a social cycle. When he gets to Z, the cycle begins again. He explicitly indicates the return to primal undiscriminated auditory space, then begins again the discovery of the vertical plane and enclosed space and numbers and measurement. Joyce is quite explicit that (page 501) as the alphabet ends its cycle we move out of visual space into discontinuous auditory space again. This he mentions as the return to "Lewd’s Carol", that is, through the looking glass into the world of non-Euclidean space once more, lewd, ignorant, tribal, involved totally as in group singing. In his "Beginnings of Architecture" Giedion cites the evidence several times that there is no architectural enclosing of space before script. Giedion does not know why this should be. Visual space alone of all the space discriminated by our various senses is continuous, uniform
and connected.
