Only such tablet

The text now says " ...only such tablet ...dated...". The observations of the Babylonians probably extended for centuries or millenia before the date of the known dated tablet. —Preceding unsigned comment added by 81.148.82.246 (talk) 11:12, 15 April 2011 (UTC)

The Babylonian observations might go back to Sumerian times, 3,500 B. C. —Preceding unsigned comment added by 109.157.131.222 (talk) 12:34, 15 April 2011 (UTC)

Value for Apogee

I find the value for the Apogee in Hipparchus time to be about 70 from vernal equinox. If correct I think this deserves a mention. However I can't find a reliable source for this, can anyone help. Sceptic1954 (talk) 17:15, 4 January 2013 (UTC)

Did Hipparchus believe that stars move and eventually perish?

I came across this.

Hipparchus anticipated that the stars come into being, slowly move during the course of centuries, and eventually perish, it was he who first catalogued the positions and magnitudes of the stars to detect such changes. Euclid produced a textbook on geometry from which humans learned for twenty-three centuries"3. Such astounding wisdom backed up by studious thinking and experimentation could have launched the world into the modern era. But it didn't. [1]

  1. Is the website reliable enough so this can go into the article?
  2. Does anyone know of other websites with the same information?

No. No. Vexen is not reliable. He or she makes no attempt to prove his or her assertions about Hipparchus. — Preceding unsigned comment added by 92.26.12.6 (talk) 14:22, 12 January 2015 (UTC)

Rename the article?

Wouldn't it be better to rename the article Hipparchus of Nicaea? This is the name with which he is more commonly remembered in modern texts. Aldux 21:41, 11 November 2005 (UTC)

I strongly disagree. He should remain as Hipparchus because the astronomer is what readers generally have in mind. Google has Hipparchus with 174,000 hits, whereas "Hipparchus of Nicaea" has only 669 hits and "Hipparchus of Rhodes" has only 602 hits. Analysis of the first few "Hipparchus" Google pages shows that the astronomer is indeed what those pages almost always discuss. These numbers also indicate that moving this page from Hipparchus to Hipparchus (astronomer) was wrong. It was also never discussed on this page. Thus I also disagree with your recent move of Hipparchus (disambiguation) to Hipparchus. — Joe Kress 06:47, 14 November 2005 (UTC)
If a majority is against moving Hipparchus (astronomer) to Hipparchus of Nicaea I won't insist. But as to the second point I have to note that Hipparchus was before only a redirect that pointed to Hipparchus (disambiguation), and I honestly thought it would be more logical the other way around. As for the change of the article name from Hipparchus to Hipparchus (astronomer), it was done quite a long time ago, 13 March 2005, and never appears to have generated protest until now. Aldux 17:51, 14 November 2005 (UTC)
I moved the article from Hipparchus (astronomer) to Hipparchus. All other possible meanings can't compete with the ancient father of astronomy. In fact, all the links to Hipparchus (which was a disambig page, remember) meant the astronomer. Moving Hipparchus to Hipparchus (astronomer) was a very bad idea, but it's all fixed now. Maurog 12:36, 25 June 2007 (UTC)
While there were many historical persons with the name Hipparchus - the Hipparchus who discovered precession is THE Hipparchus and stands above the rest (historically speaking). Terry Macro (talk) 00:15, 29 May 2013 (UTC)
The relevant policies here are WP:PRIMARYTOPIC, WP:ENGLISH WP:COMMON name, and WP:TERSE. In short, Hipparchus is always going to point to this guy as THE Hipparchus; it's not in any sense uncommon for him to be referenced simply as Hipparchus; and, given those two points, there's no good reason to force everyone to type more letters to link to or get to this article. — LlywelynII 11:21, 14 March 2015 (UTC)

Date of Discovery of Precession

Hipparchus is generally recognized as discoverer of the precession of the equinoxes in 127 bc.[39] I don't think the source is particularly painstaking and it doesn't sit readily with the entry at https://en.wikipedia.org/wiki/Axial_precession#Hipparchus.27s_discovery "The lunar eclipses he observed, for instance, took place on April 21, 146 BC, and March 21, 135 BC (Toomer 1984, p. 135 n. 14)." Maybe someone has a better source. 95.26.76.229 (talk) 15:26, 27 October 2015 (UTC)

Although I found another ref to agree with this the article is now contradictory. It says he began work on his star catlaogue in the mid 130s and then says "His interest in the fixed stars may have been inspired by...his discovery of precession, according to Ptolemy, who says that Hipparchus could not reconcile his data with earlier observations made by Timocharis and Aristillus." which would place this earlier.95.26.76.229 (talk) 16:33, 27 October 2015 (UTC)

That's not Hipparchus

It's Zoroaster--64.46.16.51 (talk) 03:33, 9 May 2016 (UTC)

Hipparchus isn't even mentioned at The School of Athens. I believe this image fails WP:PORTRAIT and will remove it. —David Eppstein (talk) 04:36, 9 May 2016 (UTC)

image

The School of Athens in this article the image is identified as zoroaster, but now it is used here for hipparchus. Which is it? 68.4.134.204 (talk) 07:15, 19 September 2013 (UTC)

I'm not a maintainer of this page but I can answer with this: As per the wikipedia page of The School of Athens, that figure could also be Strabo, a geographer philosopher historian born in the first century BCE. It's a religious painting. Nothing to do with something like mathematics or physics. It's pretty close to being anything that anybody wants.

It can be anybody as "identifications of Raphael's figures have always been hypothetical". Netweezurd (talk) 21:15, 7 December 2017 (UTC)

Commentary on Aratus and Eudoxus

Hi all, just a minor edit, Hipparchus' commentary on the phaenomena is in three books, not two. 107.15.247.72 (talk) 19:08, 31 December 2019 (UTC)

Dead link?

Berger H. Die geographischen Fragmente des Hipparch. Leipzig: B. G. Teubner, 1869.link does not work for me (Windows 7 / Chrome).Kdammers (talk) 12:50, 8 July 2020 (UTC)

It's not dead, works at least in Firefox. An availability problem, maybe? -- Elphion (talk) 13:35, 8 July 2020 (UTC)

Crater on the moon

I don't think the image being proposed adds any useful information to this article - it's not even clear which crater of many is being referenced, and is overload in a small legacy section.Pipsally (talk) 07:35, 26 April 2021 (UTC)

It perfectly fits in the Legacy section, because it depicts of what the section is talking about (The lunar crater Hipparchus and the asteroid 4000 Hipparchus are named after him.)/the article has only a few images. I don't think that it needs to be reverted again in any way. Add it again if you wish. Holloman123 (talk) 07:48, 26 April 2021 (UTC)

It's a short ection and the other image you added is already lonnger ( while being more appropriate because it's a space mission directly namd for him as an astronmer. The moon has craters named after all sorts of things, and since one can't even tell which one it is in this image there's nothing terribly notable or valuable about it.Pipsally (talk) 08:00, 26 April 2021 (UTC)

I got the image from the Greek article, and it's from the official NASA website. I can't understand how we're still talking about an addition that can help the article in many ways, especially when it is non-good article/featured. I'll also repeat that it lacks of images. Holloman123 (talk) 08:07, 26 April 2021 (UTC)

It's a great image of the crater - and is rightfully used in the crater's wikipage. It doesn't add any additional useful information here that's not already covered by simply saying he has a crater named after him. Lack of images is not a reason to include everything somehow related to the subject just to make things pretty ( which this doesn't anyway because it's too much for a brief section).Pipsally (talk) 08:41, 26 April 2021 (UTC)
I agree. The link to Hipparchus (lunar crater) suffices here, as that article does the job of identifying which crater we're talking about. -- Elphion (talk) 13:09, 26 April 2021 (UTC)
