Universal equinoctial ring dial
Three-ring universal equinoctial ring dial for all latitudes. The obverse side of the meridian ring is signed 'N Bion AParis 49 Deg:' and also displays a table of latitudes consisting of a fairly standard list of European towns and cities. The reverse side of the equinoctial ring contains a table almost completely confined to places in Spain or Spanish colonies, indicating that the original owner was probably Spanish. This is a very fine example of the three-ring form of the universal equinoctial ring dial and can be used for taking stellar altitudes, as indicated on the alidade support struts.
