Re: Ya Gnomon?/ Mathematica
Thank you, Michael. I've downloaded Sundial Construction at the URL that you gave (below) and opened it using Mathreader available at: http://www.wolfram.com/products/mathreader/ I think that I'm not going to see the sun for months whilst poring through this most thorough treatment! Thank you, I think.

Re: Ya Gnomon?
Hello everyone, Many thanks for all the EXTREMELY interesting responses. Perhaps the following title may prove useful too, this is where I got the Hero reference from. Again, thank you all. http://www.amazon.com/exec/obidos/ASIN/0691005141/qid=933291192/sr=1-1/002-2335182-6916060 -Luke

Ya Gnomon?
Luke, I believe this gnomonic progression is discussed in Robert Lawlor's Sacred Geometry. Fred

Ya Gnomon?
Hello everyone, Has anyone ever seen gnomon defined as such? Almost two thousand years ago, Hero of Alexandria defined the gnomon as that form which, when added to some form, results in a new form, similar to the original. In a spiral seashell, for example, we see that each new section of growth (the gnomon) resembles its predecessor and maintains the shell's overall shape. -Luke
Ya Gnomon?
Message text written by Luke Coletti Has anyone ever seen gnomon defined as such? No, but the Greeks from the 3rd century BC and later the Romans, used the term to refer to what we'd now call the gnomon's point rather than its edge. I suspect that Ptolemy or Vitrvius defined it but cannot today find the reference. Patrick
