The Larkin Memorial Sundial (LMS) is a variety of the classic equatorial sundial, often referred to as a "bowstring" equatorial sundial (similar to the "bow" in "bow and arrow"). The sundial is actually a reduced model of the Earth: visualize a bare-bones globe for which all that remains is one-half of the Equator, one meridian (line of longitude), and the Earth's axis of rotation. The time scale, also known as the equatorial band, represents one-half of the Equator. The vertically-oriented "bow" represents a single line of longitude, and is referred to as the "meridian band." The gnomon (or style) is a thin rod (the "bowstring") representing the Earth's axis of rotation. The bowstring is connected to the bow at the equivalent of the Earth's North and South Poles. The LMS bowstring features an analemma-shaped gnomon that can be used to determine the time of day as well as the approximate day of the year.
