>as far as I know you can not use lines on an Analemmatic Sundial.<

Yes that's right but I think that John has abandoned his idea of an
analemmatic dial in favour of this suggestion of a conventional horizontal
dial but one without a gnomon.  Instead of a gnomon he would use a human
standing at the correct spot for his height.  This person's head would
therefore form a nodus whose shadow would fall on hourlines drawn from the
dial's origin.  Not only would it make it easier to use in low latitudes it
would also be easier for use by persons of significant variation in height
- both problems with true analemmatic dials.

I only know of one such dial in the UK but there may be more in the US.

Sorry if we have confused you by our mail
