The tenth house is associated with one’s status in the world and life-calling. The traditional astrologers simply call this house ‘what one does’ and is the house of the mother.

“Commonly it personifies kings, princes, dukes, earls, judges, prime officers, commanders in chief, whether in armies or towns; all sorts of magistracy and officers in authority; mothers, honour, preferment, dignity, office, lawyers; the profession or trade anyone useth; it signifies kingdoms, empires, dukedoms, counties.
It hath of colours red and white, and ruleth the knees and hams ..Its called the Medium coeli or Midheaven, and is feminine. Its cosignificators are Capricorn and Mars; either Jupiter or the Sun do much fortunate this house when they are posited therein, Saturn or South Node usually deny honour, as to persons of quality, or but little esteem in the world to a vulgar person, not much joy in his profession, trade or mystery, if a mechanic.”
