I did not know if a chart comparison would be successful when I started this little project, but I was intrigued enough to give it a go.
I had no birth times for the two principals – Abe Lincoln and John Wilkes Booth – so I used noon for both. I did find a time for the fatal shot inflicted on the late President; a source said it occurred at 10:13 pm on the night of April 14, 1865. The President lingered for some nine hours before he finally breathed his last.
This composite chart has Abe Lincoln in the center ring, Booth in the middle ring, and the fatal shot in the outer ring representing the transits. I should maybe have put the assassination in the center, since it is the only one to be specific as to time; you are free to construct such a chart on your own software and see what that yields. I will tell you that the assassination chart yields an ascendant of 9 degrees, 21' Sagittarius (with the Moon rising at 9 degrees, 12' of Sag), and the MC is at 26 degrees, 14' Virgo.
The way these charts interlock is at first glance far too complex to treat fully in one article. There are many planets in a narrow slice from 7 to 14 degrees of the signs, another group at 29 or 00 degrees of signs (which is a harmonic of the first group), and some more at 22 to 27 degrees of the signs.
Let's start by listing the planets at 7 to 14 degrees of the signs.
In Pres. Lincoln's chart: Mercury at 10 Pisces, Pluto at 13 Pisces.
In Mr. Booth's chart: Neptune at 10 Aquarius, Uranus at 12 Pisces, North Node at 12 Aries, and Jupiter at 8 Virgo. Mr. Booth has Jupiter, the planet of the actor, inconjunct Neptune in Capricorn and opposite Uranus in Pisces.
In the transit chart of the assassination: Neptune at 8 Aries, Pluto at 12 Taurus, Mercury at 14 Taurus, Mars at 8 Cancer, Moon at 9 Sag.
