An Equinoctial Dial is a type of sundial designed with its dial plate aligned parallel to the Earth\'s equator, allowing accurate time measurement throughout the year when correctly oriented. Frequently crafted in brass or bronze, equinoctial dials became popular during the seventeenth and eighteenth centuries among travellers, scientists and gentlemen interested in astronomy and navigation. Antique examples are admired for their precision engineering and historical significance. *Related Terms*\ Astronomical Instruments, Brass Sundial, Compass, Scientific Instruments, Sundial, Timekeeping.
