This gilt brass universal equinoctial dial consists of a flat, cylindrical box containing a compass, covered only by the hinged ring of the dial. Both a hinged upper lid and an arm for adjusting the latitude on the attached dial are now missing.
On the hinged ring, a rotating OUTER RING is inscribed on its OUTER surface with a scale of Italian hours numbered 1 to 24 by one, subdivided to the quarter hour. A fixed INNER RING is inscribed with a similar scale of hours, numbered 1 to 12 twice. In the centre is the pin gnomon, held in place by a cross piece.
On the INNER surface, the rotating outer ring is inscribed: ' * * CIRCVLUS * AEQVINOCTIALIS * VT * MONSTRAT * HORAS * GERMANIAE * ET * ITALIAE * * ' and the fixed inner ring is again marked with a scale of hours numbered 1 to 12 twice.
In the CENTRE of the cylindrical BOX is a compass. The names of the winds are inscribed in Italian on the plate around it: ' TRAMONTANA . . GRECO . . LEVANTE . . SCROCHO [Sirocco] [sic] . . MEZOGIORNO . . GARBINO . . PONENTE . . MAESTRO' and 32 compass points are indicated by alternating red and black pointers. North is marked by a fleur-de-lis, and magnetic deviation is indicated for N7°E. Around the edge the names of the eight main directions are inscribed in English, alternating with star punches.
The BOTTOM of the compass box is inscribed in a radiating design with the names of 22 European cities and their latitudes: 'GENEVA 43', 'FRANCFORT 50', 'DANZICK 55', 'COMPOSTEL 44', 'BASEL 47', 'BRVSSELE 51', 'AVSBVRCH 48', 'AMSTERDAM 52', 'ANTVERPIA 51', 'WITENBERG 52', 'VIENNA 48', 'VENETIAE 45', 'STRASBVRG 48', 'SAVOYA 43', 'ROMA 42', 'PARISIA 48', 'PRAGA 50', 'PORTVGAEL 41', 'NIERNBERG 49', 'MAILLANT 45', 'LONDEN 52', 'HAMBVRG 55'. Around the centre is another, brief inscription: ‘GRADE * ELEVATIO * POLI * *’ and a star symbol is also punched on an inner circle.
The signature of the maker and date of production are inscribed around the curved sides of the box.

- Curator's comments
- This universal equinoctial dial is very similar to that in the compendium by Melchior Reichle (EPACT 1998: http://www.mhs.ox.ac.uk/epact/catalogue.php?ENumber=37591 [British Museum: reg. no. 1865,0620.5]. Although the arm for adjusting latitude is missing from this one, it can be assumed that the mechanisms were similar.
This is the only known instrument by Cornelius van den Eedt.
