RE: Time Museum Auction

There is evidently one other book of the series, titled "Time Measuring Instruments, Water-clocks, Sand-glasses, Fire-clocks." It is also a well-done book, but not as interesting for me personally as the Astrolabe book. It is interesting that it is also sub-titled as "Volume 1, Part 3." The Astro

Re: Monumental Statistics?

In an article in Volume 2 Number 4 of The Compendium,  I briefly discussed sundial size using the Jaipur, Disney and Augustus sundials.  I compared them using isometric drawings that I made.  On the basis of area occupied by each dial, I calculated the following: Augustus   -   103000 sq. ft. J

Re: Monumental Statistics?

The Mont-Saint-Michel sundial lasted only a equinox season in 1988. But in France there is now la "Nef Solaire" in Tavel that is "only" 17m high : http://www.ac-montpellier.fr/scphysiques/Nef_Solaire/nef_solaire.htm and the sundial on the Place de la Concorde in Paris with the Obelisk, both design

Re: seminar

I have not done this, but a few thoughts: I would start by talking (preferably outdoors) about the sun and where it casts a shadow over the course of a day and a year. This is where it is important for the students to develop some understanding. Nothing is gained if at the end the whole thing s

Re: Time Museum Auction

The Time Museum Catalog by Anthony Turner: Volume 1, Part 1 Astrolabes, and Part 3 Water-Clocks, Sand-Glasses and Fire Clocks have been published, are out of print, and are available from used book dealers. Part 3 has the best English-language survey of water clocks (about 70 pages) that I ha

old scientific dial

Greetings fellow dialists, During the recent tour of Austria by the British Sundial Society we were shown a dial on the wall of St. Stephen's Cathedral in Vienna which is thought to date from 1445. It is believed to be the first in the western world to have its gnomon in line with the earth's axis

Re: Dial Size

Bill Re-reading your message, you'd base size on shadow velocity. How interesting! I like that! See everybody, shadow velocity has a use after all! (Of course, shadow velocity is very closely related to projection distance) John John L. Carmichael Jr. Sundial Sculptures 925 E. Foothills Dr. T

Re: Monumental Statistics?

Minami-Mura Sundial: Dimensions unknown Dear John, Minami-mura tells the size of the Gnomon: 37,3 metres high mi (mittsu) = 3, na (nanatsu) = 7, mi = 3 (an old way of Japanese counting) Minami-mura is the name of the village, where the sundial was built on the roof of a congress hall. (See

Re: Monumental Statistics?

John, What do you think of the dial in France at Mont St. Michel? The top of the cathedral on top of an island is the endpoint of the gnomon for a dial on the beach. It only works at the equinoxes, but still is a sundial. I don't know if it still exist. More information has circulated on the list

Re: Monumental Statistics?

John, It my understanding the the Minnamimura gnomon height is 37.3 meters. This issue of the largest is a tough one but one that a lot of diallist and non-diallist alike are interested in. Maybe NASS should undertake documenting the dimensions of the larger dials and post it on the web si

Re: Dial Size

Bill. I too tend to favor a definition of size that considers shadow projection distance. But I've never ever heard size measurements done using this criteria. I sort of like your idea of using the equinox noon distance since it is one of the basic measurable qualities that all sundials have. (h

Monumental Statistics?

Hello All: Please excuse my flood of questions lately, but new ones keep coming up. How do I answer this question that people have asked me over and over?: What is the largest sundial in the world and how does Kitt Peak compare? I don't want to make any claims that are untrue. Sounding too muc
