content: This brass universal equinoctial ring dial consists of a meridian (outer) ring, hour (inner) ring, rotating crosspiece or bridge, and sliding suspension ring/handle with two chain links. The meridian ring is calibrated for northern and southern latitudes on both sides from 90 to 0 to 80 by single degrees. The hour ring is calibrated on both sides from I to XII x 2, by I with quarter-hour divisions. There is a pinhole gnomon in the bridge which slides over a calendar scale calibrated by month (in Spanish?) and also marked with the characters of the constellations. Both sides of the meridian ring are engraved with a list of 15 cities and latitudes. One side is marked: "Coppo 25; Copupo 30; Lig 30; Qiullta Sn Jan 32; Valpso Sn Tago 33; Maule 34". The opposite side is marked: "Bucnui Menza 34; Conceptn Chilln 36; S Fee Avco 37; Saldea 40; Chilo 40". These appear to be cities in what is now Chile and Argentina. Another alternate spelling of the maker's name is "Lorenz Grassl"; he worked in Augsburg.
