Let's try another example to see where it would have led me. (I don't know the outcome as I start typing this.)
Thomas Jefferson was born April 13, 1743, in Shadwell, Virginia. No time is known for sure, though there are a few disconnected diary entries about surrounding events that could be interpreted many ways. I rectified his chart to 11 PM LMT, a time at the far other end of the day from what anyone else has proposed, based on my certainty that his Moon was in Sagittarius, not Scorpio. (His chart is so important in history that I couldn't leave it alone.) Does a Novien-based narrowing of possible birth times take us in the same direction?
Here are his Novien positions for 0:00 and 24:00 LAT on his birth date, sorted by 90°:

What non-lunar aspects do we see in the Novien over the course of the day, prioritizing faster planets? Mars and Saturn are square all day. Mercury opposes Uranus early in the day, then moves past and makes no further aspects. I might have been tempted to say the birth needed to be in the first half of the day to retain this except
he has a partile Mercury-Uranus sextile at birth anyway; so this really tells us nothing useful.
We can check Novien positions aspecting his nativity. We find the following possibilities that change significantly over the course of the day:
- Novien Sun begins the day closely conjunct natal Jupiter. Jefferson was many Jupiterian things (statesman, diplomat, academic level scholar, wealthy landowner), but he was emphatically not a royalist as Sun conjunct a Leo Jupiter suggests. I would have avoided the earliest part of the day, tentatively.
- Novien Sun squares his Moon in the second half of the day (perhaps the late afternoon). That's not bad.
- Novien Venus conjoins natal Mercury at the end of the day. Jefferson was a gracious, gifted speaker with a diplomat's tongue (nonetheless barbed), but it's hard for me to say he was a Mercury-Venus type.
- Novien Mercury began the day exactly opposite natal Neptune, which doesn't fit at all. It ends the day, almost exactly square his Sun, which is fitting but perhaps too neutral to be sure about.
All I get from this is that he almost certainly was not born in the earliest hours of the day - say, not before about 8 AM (giving Mercury time to clear Neptune and the Sun-Jupiter conjunction time to distance) - and might
have been born in the last three hours to provide the Sun-Mercury (less certain).
Ruling out the first eight hours changes Moon's possible range to 23°44' Tau - 4°39' Leo. This is too wide, nearly a quarter of the circle allowing almost every possible aspect. If (feeling a little desperate) we secide to go with the Mercury square to natal Sun, a crude (still a bit too early) 9 AM LAT chart updates our table as follows:
Code: Select all
Mar 9°13' Can Mer 0°02' Cap
Sat 11°04' Lib Mar 9°24' Can
Nep 14°35' Can Sat 11°02' Lib
Moo 21°22' Can Nep 14°36' Can
Sun 22°44' Leo Moo 4°39' Leo
Jup 1°56' Sag Sun 23°50' Leo
Ven 2°43' Pis Jup 1°52' Sag
Plu 11°44' Vir Ven 4°05' Pis
Ura 22°05' Gem Plu 11°42' Vir
Mer 28°32' Sag Ura 22°06' Gem
(Note that Mercury is still 4° from square natal Sun, so even this is too early if we are looking for that aspect.)
The main consideration at this point is whether Moon makes any telltale aspects. It moves from 22° Cancer to 5° Leo during the period. In this time, it makes no aspects in the Novien. In the natal, though, it makes quite a few - square natal Venus-Pluto at 24-25° Aries-Libra (their aspect is close; do we need anything to reinforce this?), an important-seeming conjunction with Mars at 28° Cancer (but he has an Aries Sun and, for most of the day, a Scorpio Moon).
Of these, we might
think the Aries Mars is worth exploring. A 3° from it runs from 24°42' Cancer to 0°42' Leo. If we accept that, it leads us the range (approx) 9:45 to 11:06 PM.
FWIW (maybe not much, since both are speculative), this range does include the 11 PM I selected. This also isn't the strongest example, except that it allowed me to show method,
how these tools might be used.
