Re: Fw: Historical locations and longitudes
Dear John, Name on dial Longitude Fort St George 86d E (perhaps Madras?) Spot on! Fort St George is still there on the beach, the centre of the administration of the state of Tamil Nadu (formerly Madras State) in the city of Chennai (once Madras)... cheers, Peter -- Peter Mayer | [EMAIL PROTECTED] Politics Department | University of Adelaide | 'phone:+61.8 8303 5606/5610 Adelaide, SA 5005 | FAX: (+61.8) 8303 3446 AUSTRALIA | --

Madras (Fort St. George) is 80 deg 14 min E according to Norie's Tables, while Calcutta is nearer at 88 deg 20 min E but that is at Fort William. Never mind, John Harrison will soon be along.

Fw: Historical locations and longitudes
Dr J R DavisFlowton, UK52.08N, 1.043Eemail: [EMAIL PROTECTED] - Original Message - From: John Davis To: Mailinglist Sundial Sent: 19 July 2001 15:09 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!
