We should have an article on every pyramid and every nome in Ancient Egypt. I'm sure the rest of us can think of other articles we should have.
To start with, most of the general history articles badly need attention. And I'm told that at least some of the dynasty articles need work. Any other candidates?
- Standardize the Chronology.
A boring task, but the benefit of doing it is that you can set the dates !(e.g., why say Khufu lived 2589-2566? As long as you keep the length of his reign correct, or cite a respected source, you can date it 2590-2567 or 2585-2563)
Anyone? I consider this probably the most unimportant of tasks on Wikipedia, but if you believe it needs to be done . . .
This is a project I'd like to take on some day, & could be applied to more of Wikipedia than just Ancient Egypt. Take one of the standard authorities of history or culture -- Herotodus, the Elder Pliny, the writings of Breasted or Kenneth Kitchen, & see if you can't smoothly merge quotations or information into relevant articles. Probably a good exercise for someone who owns one of those impressive texts, yet can't get access to a research library.

In these changes, @PostaDiDonna: replaced the illustration File:Eratosthenes_measure_of_Earth_circumference.svg with File:Eratostene--Calcolo_Raggio_Terrestre.jpg.
Though I agree with the new caption noting that Syene and Alexandria are not on the same meridian, I believe that the original image is more accurate as the angle is to scale and being an SVG, it can be easily translated.
May I get a second opinion on this?
Thanks,

- Done I've updated it as there has been no objection. cmɢʟee⎆τaʟκ 22:43, 19 April 2022 (UTC)
- Better late than never, they say… Well, I have looked at @PostaDiDonna:’s changes on this page as well as on Earth's circumference#Eratosthenes and frankly, this user’s edits look biased to me. Basically the only reference they quote is Lucio Russo’s book The Forgotten Revolution, and they even went so far as to remove most if not all other references when they disagreed with that book.
- While it is a very good and informative book, I hardly see how it makes it worth removing other references, such as Ian Ridpath’s book The Illustrated Encyclopedia of the Universe; Albert van Helden’s book Measuring the Universe: Cosmic Dimensions from Aristarchus to Halley; or an article by Raymond Mercier in The History of Cartography.
- I consider the removal of these references a loss for the Wikipedia community—not everyone will, like I did, delve deep into the history of the pages to find other references than Russo’s book.
- I have left a long message on their user page (although they seem to have stopped visiting Wikipedia in September 2020) asking for their rationale for replacing all those references by a single reference.
- Meanwhile, I will try my best to modify the pages Earth's circumference#Eratosthenes and Eratosthenes to mention the above sources once again, giving them a more neutral point of view.

- Come to think of it, I suspect PostaDiDonna to be Dennis Rawlins or someone close to him, as one of his articles is also extensively referenced.

Hy I want to put some information about geometry 103.150.209.69 (talk) 17:34, 1 June 2022 (UTC)
So we get another one of these fabricated portraits of the 17th/18th century, without explanation and without sourcing (even in the commons file). Good work! 2A02:AA1:1020:A09C:59CD:2C68:3B5E:177A (talk) 16:58, 25 July 2022 (UTC)
- Yup, because they're public domain! What would you prefer? Furius (talk) 19:22, 25 July 2022 (UTC)
- A note that it's a fantasy portrait (and not based on, say, a contemporary sculpture) would be a good start. Then add source info. 2A02:AA1:1020:A09C:59CD:2C68:3B5E:177A (talk) 09:41, 26 July 2022 (UTC)
- Ok, I've chased this down and it turns out that it is based on an ancient object. No idea whether Lippert had any good reason for thinking sad object depicted Eratosthenes. Probably not. Furius (talk) 20:37, 26 July 2022 (UTC)
This section:
The simplified method works by considering two cities along the same meridian and measuring both the distance between them and the difference in angles of the shadows cast by the sun on a vertical rod (a gnomon) in each city at noon on the summer solstice.
I don't think there is any requirement for the two cities to be at the same meridian if each measurement is taken at Local Apparent Noon (LAN). At LAN in Syene at summer solstice there would be no shadow and at Alexandria On the same day LAN could be determined as the time the shadow of a gnomon was at it shortest.CaptCarlsen (talk) 16:31, 17 February 2024 (UTC)

As I understand it, he was from Syene, which is now Aswan Egypt.
This was a town on the Nile, near Elephantine.
I think this page is mistaken about the location of his home town.
Aswan really is due south of Alexandria. Jonathan Keohane (talk) 22:35, 13 September 2024 (UTC)
- No, he was from Cyrene in North Africa. Syene is involved in the story about his measurement of the circumference of the earth, but it's not his hometown. Furius (talk) 08:11, 14 September 2024 (UTC)
