Equinoctial dial Long Caption: Universal equinoctial dial for all latitudes. This is one of the few instruments in the collection (other than the universal equinoctial ring dials) that can be used for northern and southern latitudes. Not only are there two hour scales, but the compass card is also marked for the two hemispheres. This suggests that it was intended for use by someone who travelled widely throughout the world, and it is certainly small enough to be easily portable.
