Re: Sundial Cupolas
Hi Thierry: I would call the structure at Westminster a sundial tower and not a sundial cupola. But the idea is about the same. thanks for the photos. - Original Message - From: Thierry van Steenberghe To: John Carmichael Cc: Sundial List Sent: Tuesday, March 22, 2005 9:23 AM Subject: Re: Sundial Cupolas In addition to my earlier message re St Margaret, you can see a nice picture of the church (and one of the dials) at http://www.westminster-abbey.org/stmargarets/index.htmlwhile the dials themselves are described athttp://www.westminster-abbey.org/stmargarets/guide/tow_bell.htmThierry-- __Thierry van Steenberghe50.5N 4.3E__ John Carmichael wrote: Hello All: [...] Have any of you ever seen a cupola or "clock tower" with sundials instead of clocks?

John Carmichael wrote: Hello All: [...] Have any of you ever seen a cupola or "clock tower" with sundials instead of clocks? I remember that St Margaret church, near Westminster, London (UK) has a square tower with a round blue sundial on each of the four faces, yes, including north. (I can't remember whether this is instead or in addition to mechanical clock faces: does it matter?) Now, I was wondering: is "cupola" the right term for this thing? In French you call it "une lanterne", while "une coupole" is a dome; of course, English is not my mother language, is there any architectural terminology buff out there to, well, enlight me (éclairer ma lanterne)?

Re: Sundial Cupolas
examples you found really are beautiful and quite ornate. My design will be more American in style, but basically the same idea. By the way, if any of you design a sundial cupola, be careful to watch out for shading from roof eave overhang. The "Pagoda" designs have big overhangs that might shade the southern dials at midday in the summer. John - Original Message - From: "Frans W.

Re: Sundial Cupolas
been mentioned to me by the people on the Sundial List. In the United States, wooden cupolas with copper roofs are somewhat common in New England. They were usually used to vent hot air out of a building's attic. They were also used for bird houses and clocks. Now, they are usually just ornamental. The old one in Cambridge is of stone. I wonder if there are any old wooden cupolas in the US with sundials. I don't think there are any in the NASS registry. I'll send you a drawing (in progress) of my cupola design by separate email.

Ephemeris program
Dear all, Have you ever wanted to determine the average EoT for the 16ht century or the solar radiation received by a sundial surface along a whole year or things like that?... No program makes such specific calculations and for many of us C++ or Java programming may be unaffordable. Well, there is a wonderful ephemeris freeware at http://www.alcyone-ephemeris.info/main.html that, among other things, processes scripts made by the user. These scripts are very powerful and simple to build and deserve spending some time with them. The whole software is really astonishing! Now changing the topic: has anyone tried one of these little solar telescopes made by Coronado? Are they as impressive as they seem? Best regards, Anselmo -

RE: high dials
There is a moderate sized brass South facing sundial about 25 feet up at the top of a stair turret at Axbridge church, Somerset. I've always wondered how it was to be read - unless you could climb out onto the roof and peer over the edge. But it wouldn't be much use for setting the clock, either. Unless of course, following Mike Shaw's suggestion, horses were MUCH, MUCH bigger at the start of the 19th century - or perhaps the then Squire had a personal elephant with a really spectacular howdah? ;-) Andrew James PRI Limited, PRI House, Moorside Road Winchester, Hampshire SO23 7RX United Kingdom Tel: +44 (0) 1962 840048 Fax: +44 (0) 1962 841046 www.pri.co.uk The Intelligent Metering Company This correspondence is confidential and is solely for the intended recipient(s).

Re: Re: high dials
Hi, as you know my researche is faced on medieval sundials, and usually I find them almost at eye hight, but sometime I found many very high on the wall. In some case I may know why. One example for all: in Piacenza (Italy) there is a magnificent sundial on the cathedral, it is a statue with the sundial in his hands (you may see it in my article on GI (orologi solari medievali a 'tutto tondo'). The statue is more than 10 meter hight on a pillar of the church and the lines are very hard to be read. I suppose that all the medieval sundials were painted so they were more easy to be read even in hight places but nevertheless more than ten meter is too much. One may puzzle on it: "why so hight?", but the reason is lighted by the name of the squeare facing the dial. The squeare is named "little squeare of the cloisters". Today the cloisters and the cemetery of the priests, that was inside the cloisters, are not more there. The name of the squeare say "cloisters", this may mean two levels of cloister, one up the other. I saw other double cloisters in my trip looking for medieval sundials, and just in another one in South of Italy I found a medieval sundial easy readable only standing on the floor of the second level cloister, the dial, not more than 30 cm diameter, was very close to the roof and unfindable from the ground, while at the second cloister level you may find it al eye level.
