Armilliary[edit]

I wanted to put a link from Armilliary to Armillary sphere as well - because though not as widely used its a perfectly valid spelling I think. See [1]. But I can't work out how to add it, because the top part of the page with the title and bracketed part where it says 'redirected from' doesn't show up when I edited the page. I would be very appreciative if someone could show me how to do this.

Problem with Chinese[edit]

Please notice that, in Chinese 渾儀 & 渾象 are different things.

渾儀 is that similar to western ones, with many rings to assist astronomers' observation. 渾象 is a big sphere with dots representing stars, to represent the circulation of Celestial sphere. (Some even big enough to let people get into it, and the "stars" are holes on the sphere, therefore the people can see spot of lights inside it. Just like the modern Planetarium dome)

I don't know how should they be distinguished in English, but they should be distinguished. Otherwise the readers may be confused. (The book of Joseph Needham helps?)--Fongyun (talk) 10:35, 24 December 2008 (UTC)

Seamless hollow sphere[edit]

Modern man can't seamless hollow sphere?

History[edit]

[edit] Hellenistic world

The Greek astronomer Hipparchus (c. 190 – c. 120 BC) credited Eratosthenes (276 –194 BC) as the inventor of the armillary sphere.[1][2][3][4][5][6] The name of this device comes ultimately from the Latin armilla (circle, bracelet), since it has a skeleton made of graduated metal circles linking the poles and representing the equator, the ecliptic, meridians and parallels???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? ??????????????????????????????????????????????????????????????????????????????????????????????????? ???????????????????????????????????? —Preceding unsigned comment added by 202.70.58.206 (talk) 11:55, 20 May 2010 (UTC)

The article doesn't say that we don't know how to do it, and already states one way to make one. -- SEWilco (talk) 05:34, 5 January 2009 (UTC)

Difficult to read[edit]

The section on "how to use" this device is very awkward. Can it be rewritten by someone with knowledge of the subject?

Good use of how to use[edit]

I really like how you added a use and specific descriptions of the rings. Many older astronomy instrument pages proved the information and pictures, but do not inform the reader on how to use these instruments of give the reader any idea of it. Nguyen.mkhoa (talk) 19:10, 13 September 2013 (UTC)
