Not all sundials tell the truth. Some dials such as this Italian dial may look beautiful, but cannot tell time. A true "pillar" dial would have the III and IX hours equidistant from noon to sunrise (the first hour) or sunset (the XII hour). Learn how to make sundials.

	Grand Forks	North Dakota	USA	Armillary	Dial 282
	A large brass and cast iron armillary dial with full equatorial and equinoctial colure rings, two tropic rings and Arctic and Antarctic circle rings. The sphere is tilted so the central gnomon points to celestial north and is mounted in a four-legged stand. The gnomon includes a nodus that casts a shadow on a plate with engraved date analemma.
