Subject: Historical locations and longitudes Hi colleagues,
I have recently had the opportunity to inspect a superb
bronze horizontal dial made by George Adams (the elder) in the second quarter of
the 18th century.
Amongst other exiting details of the engraving, it carries
the names of 32 cities or locations worldwide in the chapter ring. The
names are evenly distributed with two between each pair of hour numerals,
but small arrows identify the time of noon at these locations (compared to that
of the dial, located at around 1 degree East) to the nearest
minute.
Many of the cities still have the same names: Dublin,
Lisbon, Boston etc. Some are easy to guess: Dantzick = Gdansk;
Constanstinople = Istanbul; Berbadoes = Barbados etc. However, some have
me baffled and hence I'm posting this looking for help, please. Can anyone
identify the following locations, with very approximate longitudes calculated
from the dial. I say approximate because some of the known cities have
large inaccuracies compared to modern values, eg although Lisbon is right to
half a degree, "Pekin in China" is 16 degrees off the value my atlas gives for
Bejing!
Name on
dial Longitude
Fort St George
86d E (perhaps Madras?)
Cape Comorm
79d E
Isphan
56d E
Cainiec 27d
E
St Mich. Isle
28d W
Ca. Spir
Sancto 41d
W
Ca Fare
Freezld 50d
W
Port Concepn
110d E
Compostetta 117d
W
Note that the engraving makes some characters difficult to
read and the above list might have mis-identified in for m, f for the long
s etc.
Here's hoping the list includes some historical
cartographers!
John
