A sundial cannon mounted on a marble sundial base

• ... that the Sundial cannon (pictured) is triggered by the sun and fires at noon? Source 1: The Illustrated History of Guns: From First Firearms to Semiautomatic Weapons quote: SUNDIAL GUN Made in 1788, this "gun" uses the heat of the sun's rays, rather than any type of lock, to fire. The purpose of these so-called sundial guns is to announce the arrival of noon. Source 2: R. Newton Mayall; Margaret W. Mayall (14 June 2012). Sundials: Their Construction and Use. Courier Corporation. p. 227. ISBN 978-0-486-15707-8. Quote: A dry wadding is rammed home in the muzzle of the gun and when the dial is mounted upon the parallel for which it is cut, the gun would discharge at tweleve o'clock noon fired by the concentrated rays of the sun as it crossed the line. Source 3: Hearst Magazines (July 1911). Popular Mechanics. Hearst Magazines. p. 1. ISSN 00324558. Quote: As the sun works around to noon, the solar rays are focused on the fuse, and with the blast, liberated woman knows that dinner is served.

• Reviewed: TBD asap Template:Did you know nominations/Sam Darnold Review was done after review by Mike Peel

Created by Dr.K. (talk). Self-nominated at 09:32, 7 January 2017 (UTC).

• Article is new and long enough. Hook is interesting and concise. I can't access the source via google books but this seems uncontroversial enough to accept on good faith. I've added the commonscat and an image to the article; an image could also be added to this nomination if desired. Also, a second piece of info could potentially be added to the hook (e.g., what they were used to signal). QPQ needed before this DYK is used. Mike Peel (talk) 12:15, 7 January 2017 (UTC)

• @Mike Peel: Thank you Mike for your review and for finding pictures for the article. Although the link for source 1 actually opens for me, I also added two additional references with quotes for the hook. Hopefully these work for you. I also did the QpQ. As far as your suggestion to add more details to the hook regarding the purpose, I propose ALT1 below. By the way, the dinner part of ALT1 is covered by Source 3. Dr. K. 20:33, 7 January 2017 (UTC)

• ALT1

  @Dr.K.: Looking good. A minor concern: ALT1 uses "and" twice, could you reword it to avoid that? Then I think it's ready to go. Thanks. Mike Peel (talk) 07:01, 8 January 2017 (UTC)

  @Mike Peel: Yeah, I know. That's what happens when you add more details to the hook. I saw that, but I thought it made it more dynamic; although I did have my doubts. Dr. K. 07:31, 8 January 2017 (UTC)

• How about ALT2 then:
• ALT2
• ... that the Sundial cannon (pictured) fires at noon, after being triggered by the sun, and was used to signal dinnertime?
  • Good to go with ALT2. Thanks. Mike Peel (talk) 08:55, 8 January 2017 (UTC)
    • Thank you also Mike for your helpful suggestions and improvements to the article. Best regards. Dr. K. 09:29, 8 January 2017 (UTC)
