Eight year-old boy shown for vertical scale.
View from the west (facing almost due east). The meridian band runs north-south; the gnomon, representing the Earth's axis of rotation, intersects the semi-circular meridian band at the equivalent of the Earth's North and South Poles. Eight year-old boy is 51.5 inches (130.81 cm) tall.

Boy shown for horizontal scale.
View from the south (facing north), looking along the meridian band. The equatorial band (time scale) runs east-west (right-left). Boy is 51.5 inches (130.81 cm) tall, shown lying along the time scale. The meridian band ('bow') bisects the equatorial band ('time scale'); the 12 o'clock noon hour line is located on the time scale where the two bands intersect (since solar noon occurs when the Sun crosses the observer's meridian). Facing north, morning times are located on the left side of the equatorial band; afternoon times are on the right.
