Sundials are the oldest known device for telling the time. As the earth rotates and the sun appears to move across the sky, the shadow cast on the scale indicates the time of day. This dial was constructed in 1968 and represents a globe made from a series of rings. The rings are called armillae in Latin, so it is called an armillary dial. The hour scale is on the northern half of the ring representing the equator. Image]
