Talk:Alidade

Too specific
This article is too specific in referring to the alidade. The alidade is a very general component of many different instruments and is not specific to a theodolite, sextant or other. As well, plane tables using alidades are specific instruments and should be discussed elsewhere.

This article should be renamed Alidade

Alidade is currently the name of a page that redirects to Alhidade. As such the two page names should be swapped with alhidade becoming a redirect.

Alhidade is an obscure, old spelling (as is alhidad) and is not in common use today (The Compact Edition of the Oxford English Dictionary, Oxford University Press, 1971).

In the following books (in my possession) on antique scientific instruments or the history of navigation etc, the word alhidade never occurs; only alidade is used.

Filling Wikipedia with an obscure term or forcing authors to use alidade to avoid redirects is ludicrous.

 * I would agree. Alidade is by far the more common term. CambridgeBayWeather (Talk) 23:56, 20 November 2007 (UTC)

Removed - need clarification and/or reference
I removed the following from the end of the first paragraph of the Origins section:


 * "its one of the newest editions to the Armillary sphere made by the early Islamic golden age scientists"

Perhaps the contributor meant "additions to the armillary sphere"? Nonetheless, the Armillary sphere page offers no clarification and the statement needs a reference or clarification to establish is relevance. --Michael Daly 19:26, 3 December 2007 (UTC)

adelaide, alidade

Needs reference to Osborne Fire Finder
That's it. I don't have time to add it right now, but one of the better know land-based examples of an alidade has got to be the Osborne Fire Finder, which includes a reference to this page. Seems it deserves a reference back. --Thfump (talk) 10:49, 12 November 2015 (UTC)
