Nicola,
Thanks for your addition.
Your notes bring sense to a dial with lines radiating from the footpoint of
a perpendicular gnomon
and they still exist in Italy.
On the other hand I didn't expect this in a more modern society as New York.
Best, Fer.

Dear Bob and Fer,
I have seen in Italy several sundials with the hour lines radiated from
footpoint of the vertical gnomon. This are simple sundials made from
simple people without gnomonic calculation, but only with the sun
observation. The precisione is not high, but good for living in the little
country of XVIII-XIXth century. I have seen several sundials in this mode
on house and church in Italy. Also the italian diallists point out this
dials like "pseudo-sundials", and not more time ago this was a long
diatribe on the italian mailing list on this subject. But this simple
sundials are not very rare in Italy and its are the testimoniance of
measuring time of our simple people in the country.
Thanks to all and sorry for my bad english

Bob, Nicola,
I also saw the "hourlines" on the sunny photograph of this dial but they
didn't give sense to me.
They radiate from the footpoint of the perpendicular gnomon on the wall,
I guess, and to my opinion they are not (usual) hourlines.
I don't know the text by Nicola and ask to place that text on the sundial
list so we all can learn Nicola's thoughts.
Best, Fer.

Nicola and all,
Nicola, I did not notice the hourlines until you pointed them out.
Thank you, this dial is beginning to make more sense.
I have put another page online with an edited version of Nicola's
graphic with a statement and link about the dial's concept.
