The symbolism is science or branch of knowledge that studies the symbols, although it is also known by this name to the portfolio or symbol catalogs in the world. It should be known that a symbol is a graphic representation of an image or element, said symbol must be accepted in a kind of tacit pact that is made in society to be able to define it as such. For example, raising the index finger and the middle finger is known as peace and love and at the same time victory for the letter V that is formed between them, a heart represents love, an intertwined ribbon refers to the fight against cancer, a cross is a Christian symbol and so on.
The basic purpose of symbology is to be able to convey an idea or information from one person to another through a combination of visual signs or emblems, responsible for transmitting senses or feelings to people, and in this way they can be deciphered depending on the context of the same or of the culture to which it belongs.
For a better understanding and acceptance by all symbols they only have one meaning and transmit a precise message through the sign that is drawn or from which a silhouette is created, these should not strictly resemble what they represent, for example, if it were not known the history of Greek mythology of the Greek god Asclepius we would wonder what a staff with two snakes entangled has to do with medicine. Although they do exist taking into account real information of what they represent and that ultimately makes them easy to recognize, as is the case of national symbols with which the citizens of a country feel clearly identified and even have a feeling of belonging. For them, these can be the anthem, the flag and the national emblem, although there are times when the feeling is so strong that the folklore and indigenous dishes of the region are taken into account.
There are infinite areas in which symbols are protagonists in their representation, such as in politics, religion, sports, or also areas of scientific knowledge such as mathematics, physics or chemistry.
