Description: | Astronomical compendium comprising of a nocturnal (slit type), epact calendar, table of latitudes, universal equinoctial dial, magnetic compass and lunar volvelle. The accompanying Rojas projection disc is not part of the original item and most likely comes from reverse of a separate Gunter quadrant.
For a detailed description, please see 'Sundials at Greenwich' by Hester Higton, Oxford University Press (2002), pp318-320.
There are similar compendia by Whitwell in the Whipple Museum, Cambridge (Wh:1733) and the Museum of the History of Science, Oxford (44225).
