AZIMUTH DIAL Meaning and
Definition
-
An azimuth dial refers to a specific type of sundial or instrument used to determine the direction of the sun, as well as the corresponding time of day. It typically consists of a flat, circular plate that is marked with divisions representing specific time intervals, often in hours or minutes. The circular plate is often aligned with the Earth's magnetic field or geographic north, allowing for accurate readings.
The centerpiece of the azimuth dial is a vertical iron or magnetic needle that serves as a gnomon, casting a shadow on the circular plate. The position of the shadow on the marked divisions indicates the time of day relative to the sun's position in the sky. By observing the orientation of the shadow and the corresponding markings, one can estimate the local solar time.
Azimuth dials are mostly used in locations where the sun follows a predictable pattern throughout the day, such as near the Earth's equator, where the sun is generally high in the sky and moves in a consistent east-west trajectory. They have a long history and were widely employed for both practical and decorative purposes, providing crucial timekeeping information for various activities, including agriculture, navigation, and religious observations.
In modern times, azimuth dials are sometimes incorporated into larger astronomical or navigational instruments, such as sundials or telescopes, to assist in determining accurate time and orientation. They also serve as educational tools, helping individuals understand the movement and position of celestial bodies in relation to their local environment.

Etymology of AZIMUTH DIAL
The word "azimuth" originates from the Arabic word "as-sumūt", which means "the ways" or "the paths". In Medieval Arabic-speaking lands, "as-sumūt" was used to refer to the points on the horizon where celestial bodies rise and set. This term was later adopted by Greek astronomers and eventually became "azimuth" in English.
The use of "azimuth" in combination with "dial" likely stems from the device's function. An azimuth dial is a type of sundial used to measure the azimuth, which is the angular distance between a celestial object (such as the sun) and a specific point on the horizon. The name "azimuth dial" simply describes the instrument's purpose of determining azimuths.
