Meaning of Skull
What is Calavera:
A skull, also called a bony head, is the name given to the set of bones that make up the skeleton of the head, formed by the bones of the face and the skull, when it is stripped of flesh and skin. The word, as such, comes from Latin calvaria, which means 'skull'.
The bones of the skull fulfill the function of surrounding and protecting the brain and the sensory organs of the human being, in addition to containing the chewing apparatus. It is made up of 28 bones, of which the jaw is the only mobile bone.
In this way, the skull is made up of the following bones. In the skull, the frontal, temporal, occipital, parietal, ethmoid, sphenoid bones. In the face, the vomer bones, unguis, inferior nasal turbinate, upper jaw, lower jaw or mandible, zygomatic or malar, palatine, nasal bones and the bones of the middle ear, with the hammer, the incus and the stirrup.
The skull is also used as a symbol of death, as a sign of danger or as an indicative on the label of a toxic substance. Likewise, the skull has been used by pirates, with two crossbones and on a black background, as a symbol on their flags.
As a literary skull, it is called a popular poetic composition of a burlesque or satirical type through which ideas and feelings are expressed in a critical and irreverent tone.
Skulls began to appear in Mexico in the 19th century. They were verses that portrayed characters in public life as if they were dead. They came to suffer censures, because they were uncomfortable especially for the powerful. Usually they were accompanied by a drawing that represented a naked skull with a hat in European fashion, which was known as The Catrina wave Garbancera Skull, and whose conception was the work of the illustrator José Guadalupe Posada.
