Actually I just found a Wikipedia entry with photograph re: the Finnish politician's chart-- Ahti Karljalainen:
http://en.wikipedia.org/wiki/Ahti_Karjalainen . Kind of a strange-looking man! tsmall, see what you think. By any standards, he made a success of his career in politics and banking until his drinking got the better of him.
tsmall, I think you've done a super job of showing some problems in Mr. K's life: what do you think would account for his success?
Byjove-- hopefully you can see how, with a whole sign system, the MC probably wouldn't be the 10th house cusp; although oftentimes it would be in the 10th house. A quadrant-based system like Placidus, Prophyry, Koch, and several others would put the MC as the 10th house cusp.
You would always, either way, interpret the 10th house as saying something about the person's vocation or calling (hence our concept of career vs. "just a job",) and public image.
Then some traditional authors really seemed to peg the MC to the high point on the ecliptic at the birth moment; whereas in Maternus, mentioned above) the MC is simply pegged to the same degree as the ascendant.
I've posted Mr. K's chart using Porphyry houses. Porphyry lived in the 3rd century, but the system named for him is probably older. So this is another Hellenistic system, but not one much in use today. It is a
quadrant system, meaning that the angles start the 1st, 4th, 7th, and 10th house cusps. We still get that MC in Scorpio, but but this system symply divides the quadrants into 3 equal pie-slices each. With such a far northern birth, we still get a skewed MC/IC axis, intercepted signs, and some huge and some tiny houses. Then the sign on the house cusp and its planetary ruler may vary from whole signs.
So if we take Mr. K to have reached the peak of a political career (prime minister) and the depths of disgrace (public alcoholism)--does this chart show him better?
Dunno. However, now Jupiter moves to the (favourable) 9th house, still conjunct the MC. The bank director career may show up with the sun and part of fortune in the 2nd house. The ruler of the 8th house of "shared resources" (i.e., investments) is also now in the 2nd house (sun.) The moon moves into the 12th (bad) but Venus in the first (good) can indicate an attractive personality--very helpful for a politician.
He's still got that strong Mars in Aries as his traditional MC ruler, but now with Pisces on Mars's house cusp, the traditional ruler is beneficial Jupiter, conjunct his MC.
As a modern astrologer I would also note that domiciled Mars quintiling Mr. K's Mars-ruled MC. This probably gave him a lot of talent and ambition (quintile) to pursue his career (MC) in a very assertive, energetic way (Mars.)
Dr Farr, if you've got a moment, I'd love to see your take on this horoscope.
