If an analemmatic dial is planned for a vertical declining wall at 55° North, and the latitude on the earth's surface where this plane would be horizontal to the surface is 35° South, these two defining planes would be parallel to each other. Therefore, as the gnomon's < Not true if the vertical wall declines. Declination will bring the southern latitude closer to the equator - until it equals the equator when the declination is 90 degrees. Fred Sawyer
