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.

sundials and astrolabes

2007-10-21 Thread CS
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.

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

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.

Astrolabes by Roderick and Marjorie Webster. This book is the inaugural
volume of our catalogue project documenting the Adler’s collection of
historic scientific instruments and rare books.

The Adler Planetarium & Astronomy Museum is home to one of the world’s
great collections of astrolabes. In this volume Marjorie and the late
Roderick Webster, Adler Curators Emeriti, have carefully documented 47
astrolabes, astrolabe-quadrants, and mariner’s astrolabes. The book is
lavishly illustrated with photographs showing the front, the back, and
additional details (such as the maker’s 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.

I got the Sundial book and an Astrolabe "kit" at the Old Royal

book don't go below 30 deg latitude, and I'm ant 18 deg, it's excellent. 
I've built most of them, modified as best as possible for my latitude.

The "Make-it-yourself Astrolabe" seems to be published by the National

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

1996-08-30 Thread Charles Mollan, Samton Limited
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

Some useful essays and works on the astrolabe are appended below.

It may also interest subscribers to this list, that the Adler 
Planetarium and Astronomy Museum in Chicago will publish a 2 volume 
catalogue of its remarkable collection of astrolabes next spring.  
The first volume is devoted to western astrolabes and 
astrolabe-quadrants.  The second volume is devoted to eastern 
astrolabes and related Islamic instruments.  Both volumes are 
interpretive--meaning that they contain essays and illustrations 
setting astrolabes into their social, historical, and scientific 
contexts.  They include a comprehensive bibliography.  The principal 
authors are Roderick and Marjorie Webster, and David Pingree.  I 
wrote the interpretive essay, "Astrolabes: A Cross-Cultural and 
Social Perspective."

I have designed two Astrolabes and am particular to them over sundials.
The best reference I am aware of is called 
ALL the Astrolabes
by Harold Saunders

It it is out of print But I manages a almost completely xeroxed copy. 
Otherwise, Many back isues of astronomy magazines show methods of
construction.
Lastly find a copy of Geoffey Chaucers Treatise on the Astrolabe
If it suits anyone, I have some lovely drawings created in AutoCAD for the
designs of my astrolabes.

you will want to know about the astrolabes sold by Janus.  the fellow
who owns the company also sells a nice computer astrolabe program.
the manuals that accompany the astrolabes and software are nice
introductions to astrolabes and their principles.  in addition, he
has translated Michel's astrolabe book into English (though it
remains unpublished) and will sell you a copy if he has any left.

(this may be useful even if you read French as i think Michel's
book is no longer in print.)

you can send email to Janus at [EMAIL PROTECTED]
or telephone to 203-746-0815.  the postal address is
Janus/9 Bigelow Rd./New Fairfield CT/USA

Les,

Some books about astrolabes. I don't know if they are still available.

All the astrolabes by Harold N. Saunders, 1984. ISBN 0 906831 040 

Traite de l`astrolabe by Henri Michel, 1976. First edition published in 
1947, in 1976 a limited reprint. It is French.

Astrolabes of the world by Robert T Gunther. (A large book)
First published 1932. Reprint 1976.

Das astrolabium und die Uhr by Johann Hugin, 1978, German.
ISBN 3 921348 23 4

Articles in the bulletin of De Zonnewijzerkring (the Dutch Sundial 
Society) in dutch.

It is about 15 years ago I started with some study of the astrolabes and 
it is very interesting. I made a computerprogram to draw the tympans for 
several latitudes but it is more pleasant to study the maths first.

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.

Thanks
