The Ascendant of Jim Morrison was Aquarius.
This perhaps made him a bit cold, possibly not austere. He did “architect” a rather “translucent” image of himself. His poetry and writings could be called “ironic” in nature.
The Ascendant of Cher is Cancer. She implies a somewhat unemotional “stance.” But she is very aware of the horrors of basic everyday ordinary human tragedy.
Mariah Carey has Ascendant in Taurus. She is inherently “uncombative.”
Donald Trump has Ascendant, Leo. People presume this makes him a bit “hard,” even the color “orange.” But what it really does seems to be rooted in a square, perhaps.
Trent Reznor has Ascendant Capricorn. This makes him appear terse but with a mixed air of impartiality.
