What are the possible dates for the seven (classical/mediaeval) planets (Sun, Moon, Mars, Mercury, Jupiter, Saturn, Venus) all being in Leo?

I’m not sure how to figure this out on my own. I’m interested in this for the purposes of historical dating. Example: the planetary positions are recorded in art. These positions are only possible every so often and I’d like to know the possibilities.

Here’s one of the example. This is called the Metternich Stele, named after the Prince who received it shortly after its discovery. The original

Here’s the first drawing of it by the Russian Egyptologist V. S. Golenishchev. VSG’s Drawing

I created the house-states.txt.bz2 file in https://github.com/barrycarter/bcapps/tree/master/ASTRO/ to answer Period of unique horoscopes? and, according to this file, all 7 "planets" are in Leo during the following times:

  • BCE 3440-SEP-01 01:14 to BCE 3440-SEP-01 05:19
  • BCE 1437-AUG-25 19:38 to BCE 1437-AUG-28 08:36
  • CE 5156-JUL-25 10:49 to CE 5156-JUL-26 20:26
  • CE 5773-JUL-19 10:22 to CE 5773-JUL-21 17:27
  • CE 7125-AUG-18 14:08 to CE 7125-AUG-18 21:25
  • CE 10362-JUL-19 06:08 to CE 10362-JUL-21 11:14
  • CE 11891-AUG-12 22:08 to CE 11891-AUG-13 07:44
  • CE 14334-JUL-26 00:49 to CE 14334-JUL-28 13:30

The file covers the time frame BCE 13201-AUG-16 to CE 17191-FEB-28.

Below is a Stellarium image of when all the planets are in Leo in 5156. Note:

  • Even though the astrological sign is Leo (between 120 and 150 degrees in the ecliptic grid), precession means the planets are actually in Taurus and Gemini

  • The Stellarium timestamp, 5156-07-25 02:02:18, falls outside the time range I give above, I'm not sure why.

  • $\begingroup$ Is precession the reason why they dont recur at similar intervals? 3440BC to 1437BC is a lot more time than 5156AD to 5773AD. What would the results look like without adding the precession variable? $\endgroup$
