Re: Astrolabes
I have two commercial planispheric astrolabes. The Norman Greene one in the puzzler link below looks as if it might not be accurate, however it is easy to read in full sun. Another I have is clearly more accurate but in full sun rather hard to read. Mr Morrison's work is definitive, excellent. My DeltaCAD macro for astrolabes (planispheric) will let you check designs. I only address the sun, not other heavenly bodies. My main spreadsheet also provides planispheric astrolabe design data. I also wrote an idiot's guide to designing them. www.illustratingshadows.com and all that stuff is free.

sundials and astrolabes
Dear all I started last year to design and develop a new version 3.0 of my program Shadows. Several new features have been included and the user interface has been fully redesigned. One of the main new features is that it can now create astrolabes. For the moment only planispheric astrolabes are supported but for sure new types (universal, rojas...) will be added later. Astrolabes are not sundials as they do not tell time. But I am sure that sundial lovers will be particularly interested by astrolabes. They are really great and clever instruments and can be used for a wide variety of usages. I hope that this new version will help people rediscover these instruments. Shadows 3.0 is not yet available publicly but an alpha version is provided on the forum I open several months ago. I recently added an English section in order to receive contributions from non-French users. I will be happy to see contributions from members of this list.

Re: Metallurgy of astrolabes
On the subject of astrolabes, I notice that the wonderful Museum of the History of Science in Oxford has a special exhibition on astrolabes at the moment. See http://www.mhs.ox.ac.uk/ . This includes talks at 2:30 every Sunday on a particular astrolabe in the collection, which is the best in the world. Also, on Saturday 10 December they have a sundial-making workshop for children. I wonder if I'm too old to sneak in? Chris Lusby Taylor 51.4N, 1.3W
Metallurgy of astrolabes
Good afternoon folks, In the course of googling for other things (metallurgy of early iron wire), I came across the following sites that may be of interest to some of you. Brian Newbury of Lehigh University (Pennsylvania) studied the metallurgy of early astrolabes. The URL below is to a poster (170 kB) summarising some of his research. http://www.lehigh.edu/~inarcmet/Staff/APS%20Final%20Poster.pdf Googling for "metallurgy" + "astrolabe" + "brian newbury" gives some other results.

Re: Astrolabes
Dear Membership, Thanks for all the listings on Astrolabes! This is an area I'd neglected in my studies. I'm finding the information very interesting and have started to build a 6 inch one for my area. ( For the summer months when it isn't raining nearly every day. ) I'm also interested in early navigational methods and this fits right in. I'm also designing the prototype of the "Cycloid Polar Book Dial". I'm planning on doing it in Ceramic, but am very concerned about the accuracy of the cycloid curve and shrinking/distortion in curing. I think I'll make the two halves of the book separate so I can fit in the linear scale and test the surfaces before I add the markings and final glaze. If anyone has any hints/experiences here, I would be happy to hear them. Edley McKnight, [43.126N 123.327W] "OK, so I move around some" :-)

New Publication--Western Astrolabes
Please excuse cross-postings: The History of Astronomy Deparment of the Adler Planetarium & Astronomy Museum, Chicago, is pleased to announce the publication of Western Astrolabes by Roderick and Marjorie Webster. This book is the inaugural volume of our catalogue project documenting the Adlers collection of historic scientific instruments and rare books. The Adler Planetarium & Astronomy Museum is home to one of the worlds great collections of astrolabes. In this volume Marjorie and the late Roderick Webster, Adler Curators Emeriti, have carefully documented 47 astrolabes, astrolabe-quadrants, and mariners astrolabes. The book is lavishly illustrated with photographs showing the front, the back, and additional details (such as the makers signature) of each instrument. Introductory essays by the Websters and former Adler curator Sara Schechner Genuth explain the use of the astrolabe and its role in cultural and social history.

astrolabes
Dear all, There's been a lot of discussion recently about astrolabes. I'd like to draw people's attention to a forthcoming catalog of western astrolabes and astrolabe-quadrants at the Adler Planetarium and Astronomy Museum in Chicago. The Adler has one of the finest collections of astrolabes in North America. This catalogue not only describes the western instruments, but contains interpretive essays on astrolabes in scientific and social context. The catalog was written by Roderick and Marjorie Webster. I wrote the introductory essay on astrolabes in cross-cultural perspective. The catalog should be available in mid-May, if the printer's word is to be trusted. As soon as it's ready, I will send a notice to the list with information on how to order it.

Astrolabes & Sundials
Following the recent interest shown in Astrolabes, I have an offer for a discerning astrolable enthusiast! I have a beautiful first edition copy of the two-volume work "The Astrolabes of the World", by Robert Gunther, Oxford University Press, 1932. It can be purchased from me for 1000 Irish pounds plus postage and insurance. An Irish pound is to day worth 1.04 sterling pounds or 1.6 US dollars. Postage depends on where you are and how quickly you want delivery. As the number of participants in this sundial interest group seems to have grown greatly recently, can I please let newcomers know of my own work: I have recently published the "Irish National Inventory of Historic Scientific Instruments", a detailed listing of 5104 entries about instruments or groups of instruments in Ireland, or of Irish make outside Ireland, dating mostly to 1900 or earlier. The listing contains details of 237 old sundials of all kinds. The 501-page hard-back book, printed in a limited edition of 100 copies, is available for Irish or Sterling pounds 55, or US dollars 90, including surface postage anywhere in the world. Orders can most conventiently be made by ACCESS, VISA, EuroCard or MasterCard to Fax (+353-1) 289-7970. Personal cheques are also accepted. Please order from Charles Mollan, 17 Pine Lawn, Newtownpark Avenue, Blackrock, Co. Dublin, Ireland. Tel. (+353-1) 289-6186, e-mail [EMAIL PROTECTED] There are now only a few copies left. If anyone has information about sundials with Irish signatures, I'd be delighted to have details. Thank you (DR)CHARLES MOLLAN ** (Dr) Charles Mollan 17 Pine Lawn Newtownpark Avenue Blackrock Co.

Astrolabes
I am looking for a book or references on the mathematics and design of astrolabes. Apologies if this is a little off topic, but since the maths is not too dissimilar from that of sundials it is likely that some list members will be astrolabe designers too and I would appreciate any recommendations.
