Allen and Ridpath[edit]

I revised the paragraph added by Graduate of UCLA, B.A. Sociology, Class of 1996. Graduate of Cornell Law School, Juris Doctor, Specialization in International Law, Class of 2005. Attorney practicing in Los Angeles since 2005. Interests include astronomy (particularly the history of constellations in ancient cultures), biblical archaeology and the Dead Sea Scrolls, California history (especially pre-statehood), old maps and mapmakers, and all things English Football.

BenEsq (talk) 18:32, 29 October 2014 (UTC) about Allen's account of the history. In the first place, the suggestion that de Houtman's inspiration came from Chinese astronomy is not Allen's; Allen is simply reporting it, and mentions that it was disputed. But also, Ridpath does not address this; the referenced chapter simply indicates that Apus (and the other "Bayer's dozen") come from observations of Keyser and de Houtman, who sailed on the same voyage. BenEsq's source for Allen is a web site by Bill Thayer, who adds the following bizarre note:

According to Ian Ridpath, Chapter 1 of his book Star Tales the twelve new southern constellations were introduced later than that, and by different people altogether: Blaeu's Uranometria (1603) correctly credits them to Frederick de Houtman, who owed them in turn, however, to Pieter Dirkszoon Keyser, † 1596. (And thanks to Diana K. Rosenberg of Fixed Stars and Constellations for the heads-up.)

This misrepresents what Ridpath wrote. Ridpath makes clear that the observations were made separately by both Keyser and de Houtman (who were rivals sailing on the same voyage). Pieter Keyser was also known as "Peter Theodore", whom Allen does mention, so "later than that" and "different people altogether" are both wide of the mark. Ridpath writes that we don't know precisely who was responsible for the division of Keyser's and de Houtman's observations into the new constellations displayed on Plantius's globe that appeared very shortly afterward; it might have been any of the three of them, or some combination.

I have removed that bit as I think it is not held elsewhere...and Allen wrote it in 1899...Cas Liber (talk · contribs) 14:50, 22 September 2016 (UTC)

"Next to each other"[edit]

I'm leaving this here rather than placing a [clarify] tag so as not to interfere with a GA review, but in the line "including two stars next to each other as Delta and another two stars near each other as Kappa" does "next to each other" mean that they are close in angle as viewed from earth (and if so how close), close to each other in three-dimensional space (and again, if so, how close) or actual binary star systems? —David Eppstein (talk) 00:29, 27 October 2016 (UTC)

Lacaille didn't have the means to tell whether stars were at the same distance, so angular separation is all that is claimed. The two deltas are fairly close (104 arcsec or about 1.7 arcmin); the two kappas much wider (about 38 arcmin). Neither pair is physically close in space. -- Elphion (talk) 03:20, 27 October 2016 (UTC)

Okay. So, as always, it's a pretty good and comprehensive article. There are a few issues, but they're mainly a problem for it moving forwards, I'd say:

For purposes of completeness, I'm going to compare this to the featured article Microscopium, and check whether it has similar range of content. Having reviewed, it does. HOWEVER, it could really use at least one historical depiction of the constellation, to show how its stars (supposedly) fit the bird of paradise shape.

I'd suggest using (file information can be copied from File:Johann_Bayer_-_Uraniometria_-_Southern_Birds.jpg). Alternatively, a crop of File:Cellarius_southern_scenographic.jpg would work. Adam Cuerden (talk) 20:57, 5 December 2016 (UTC)

Sourcing looks good; information a good range of material. I think it's just the lack of a historical depiction that's holding this back. Honestly, I could probably promote without, but... Adam Cuerden (talk) 20:36, 5 December 2016 (UTC)

ok will take a look at best one to crop or use... Cas Liber (talk · contribs) 09:19, 6 December 2016 (UTC)

That'll do, methinks. It's really obvious why the Apus name's derivation from Europeans oonly getting wingless footless specimens when you see how they depict it, I think.  Pass Adam Cuerden (talk) 15:37, 6 December 2016 (UTC)
Oh, there's a point - it's probably worth discussing the Apus/Apis confusion caused by Musca's bee-era. Briefly, as it was, after all, Musca that changed. Adam Cuerden (talk) 15:46, 6 December 2016 (UTC)
