Talk:Campanus of Novara

Personal and article names
This article should probably be renamed to Campanus of Novara as cited in sources, with the qualification "Campanus is sometimes given the forename Johannes, but that name receives no confirmation in the manuscripts of his works..." Benjamin and Toomer (1971) Also, I question Clockmakers' Gallery as a WP:RS. --mikeu talk 18:17, 2 March 2011 (UTC)


 * I've renamed the page and cleaned up the links and redirects. Let me know if I've missed anything. --mikeu talk 20:07, 6 March 2011 (UTC)


 * Also known as (per Library of Congress) but I have renamed the article per WP:EN and the most common usage in authoritative sources. --mikeu talk 22:39, 6 March 2011 (UTC)
 * Campanus, de Novaria
 * Campanus, Iohannes
 * Campanus, Johannes

Horoscope house system
In a section titled "The eastern origins of the Campanus (Prime Vertical) method. Evidence from al-Bīrūnī" it is given: "Where did the method originate? I can only say that it was known in Europe before Campanus, and that when it was mentioned yet earlier by al-Bīrūnī in the Masudic Canon, there was no claim to originality implied." Given that the method is attested to some two centuries before the time of Campanus, it would seem that he could not have invented the horoscope house system that is named for him. --mikeu talk 02:29, 4 March 2011 (UTC)


 * The above has been worked into the article. --mikeu talk 20:29, 6 March 2011 (UTC)

Clocks
I've removed the following from the page, as I can not find any reliable sources to back up this statement. --mikeu talk 20:29, 6 March 2011 (UTC) His De computo ecclesiastico or Computus maior (ca. 1261 – ca. 1264) was written by Campanus for Pope Urban VI does not make any reference to a mechanical clock, thereby leading historians to believe that the clock was not invented until 1280 or so.
