The geometric figure of the pentagon is at the base of the pentagram which is a star with 5 branches.
Used by Leonardo Da Vinci, the pentagram was always considered as an object of perfection and of beauty. We find it in architecture, arts, certain coins and on some flags.In comparison with numerology, pentanalogy integrates the number 10. This number is very important because it is the symbol of evolution. In fact, the number 10 influences the pentagram particularly.
Hans Muller(1898-1985) was the first person to have discovered the system of pentanalogy. He represented the first 10 numbers in the pentagram and associated each of them with a part of the human body. He updated the specific zones. The upper portion of the pentagram represents the intellect. The lower portion represents the body, the instincts, the material. The right side of the body/the left side of the pentagram depicts the future and the left side of the body/the right side of the pentagram presents the past. The odd numbers at the tip of the star’s branches represents masculinity and extroversion and the even numbers on the concave portions of the star represents femininity and introversion.
Then Charles Gruber (1925-1990) developed the idea of the pentagram by integrating the analogy of the human body with a tree. In this manner he extended his research and defined the zones related to the numbers.
Zone 2-10 The top of the tree symbolizes the head and the crown. Importance of parents and feminine aspects (2) and of the masculine aspects (10). 3-9 The branches (the hands) represent the cycle of give(3) and take (9). 4-8 The trunk of the tree, connects the top and the bottom. 5-7 The roots represent the energy drawing faculty and the resources in the environment where one evolves.
