Hi,
Numerology has a great deal to do with the numeric value of the alphabet and there are many legends and theories about how this came about.

The alphabet itself was inspired by pictorial representations that recorded elaborate stories. These full pictographs originally were abbreviated to form hieroglyphics with each symbol depicting a word. As more time elapsed the glyphs were further reduced to represent individual sounds and then the consonants and vowels that we know today.

The modern alphabet that numerological systems are based on is derived from an earlier hieroglyphic system that is still used by Japanese and Chinese cultures. Each letter also symbolizes a number. This has remained unchanged, even though our speech patterns have evolved to make some sounds obsolete

Each sound is thought to also have an esoteric spiritual implication, with an essence that can be described as a number. Even more meaning is given to the very first letter of the word.

Here is a breakdown of the numerical vibrations of the letters in the alphabet according to ancient numerology systems that originated in Babylon and Egypt. In these systems, personality was analyzed by the first letter of the name.

A is the numerical equivalent of 1 and symbolizes confidence. When it's the first vowel in a name, the person tends to be bold. On the negative side, A can be critical of efforts of others.

B is the numerical equivalent of 2 and represents our emotions. A person with a B first letter is friendly and a homebody. On the negative side, B can be self absorbed if not a bit greedy.

C is the numerical equivalent of 3 and represents energy. C people are talented and get along well with others. Negatively, C people can be ruthless and crue
