Hi Skill, I spent quite a bit writing a response on my thoughts but didn't get to finish it, hopefully a partial reply is satiating:
The astrologer Robert Cross Smith (19th century astrologer) in A Manual of Astrology
in his section "The Fortune of Rank" mentions that the superiors Saturn, Uranus, Mars, Jupiter and the Sun angular confers to public notoriety. However, he also mentions that if out of these planets Saturn, Uranus and Mars lie in the tenth to generally
denote some sad catastrophe to finish the scheme of their nativity (155). So I looked at some assassinated people.
For example, Kennedy had Saturn in the tenth. Lincoln had Saturn in the tenth. Mussolini had Uranus in the tenth, Gandhi had Uranus conjunct the midheaven. Again however, this is subjective--how bad
depends on how much the planets are afflicted themselves and afflicting the others, especially the luminaries; he mentions—and also mentions that if the planets are assissted then the placement is also not as bad. One should not
assume (as they seem to here) this is mentioned as a guaranteed signature of ill-fate.
Another thing that may
represent rise and fall in the nativity is if the tenth lord is in the twelfth since the twelfth house is declining
and one of the most unfortunate houses; if the tenth lord is afflicted then they may most likely face disgrace or an unfortunate end to the career/reputation.
Kennedy had Saturn afflicted in Cancer in the tenth house, conjunct the midheaven in sextile with the Moon from the twelfth house. The lord of the 10th is in the 12th house. I don't see that this sextile is of much help to appease Saturn, as Saturn's dispositor Moon is weak and afflicted being in the 12th house in Virgo -- these two planets are also said to be "enemies"; of course there's reception here but I don't see it doing too much since the Moon is malignant from being in the twelfth house. Saturn is also sextiled by a Mercury/Jupiter/Mars conjunction in the eighth house; not a particularly fortunate connection with the agitated Mars (public enemies ruler). Mercury rules the 12th house of secret enemies, it seems like he had many enemies that wished his ruin.
Gandhi had Uranus conjunct the midheaven in Cancer, aspected by Mars in Scorpio by trine by 3°, and he was shot. Mars also opposes Pluto rx by only 0°44' in the eighth house, which makes this trine to Uranus very malignant; indicating a sudden violent death by piercing.
Jupiter is conjunct Pluto. It seems like Jupiter being involved may indicate a public death (as above, Kennedy also had Jupiter involved, and was killed in public).
[ to be continued:
will touch on Lincoln, Mussolini .. and also people that weren't assassinated but have similar placements ] ...
