Midpoints are an advanced form of astrology used by professional astrologers. Any two planets or other significant points are calculated, and then the midpoint between them is found, and anything which aspects this midpoint is then interpreted. Midpoint astrology was developed extensively by the “Cosmobiology” school of astrology in Germany between the two World Wars.
The use of midpoints is an ancient astrological technique that was revived by German astrologers in the 20th Century. A midpoint is the halfway point between any two planets, and any planet forming an aspect to a midpoint influences the way in which the two planets in question blend their energies.
