Nocturnal Geocoin The early nocturnals were made of wood and later made in brass. They were approximately 7" to 10" in diameter plus the length of the handle and arm. The large circle, that has the handle attached to it, lists the days and months. The center rotating disk has the time. The arm has a notch on one edge so you know to use the opposite edge for lining it up with the stars. Both the center circle (time ring) and arm rotate on an arbor which is hollowed out to use it as a sight.
