Dan,
I’m just guessing, but maybe the two holes and two spots are placed so that, no
matter what the Sun’s declination is, at least one of the spots will fall on a
smooth, uncluttered part of the floor.

Subject: Gnomon of Saint-Sulpice
Hello,
Last week I visited the meridian line of Saint-Sulpice in Paris which dates
back to 1743. After the French Revolution the Republicans chiseled out all
references to royalty from the inscriptions. I don't know why but they also
erased some of the zodiac signs. Could it have something to do with the new
Republican Calendar? Also, there are two holes for the light to enter with two
spots forming on the ground and I don't understand exactly why...
