Skull symbolism is the attachment of symbolic meaning to the human skull. The most common symbolic use of the skull is as a representation of death.
Humans can often recognize the buried fragments of an only partially revealed cranium even when other bones may look like shards of stone. The human brain has a specific region for recognizing faces,[1] and is so attuned to finding them that it can see faces in a few dots and lines or punctuation marks; the human brain cannot separate the image of the human skull from the familiar human face. Because of this, both the death and the now-past life of the skull are symbolized.
Hindu temples and depiction of some Hindu deities have displayed association with skulls.
Moreover, a human skull with its large eye sockets displays a degree of neoteny, which humans often find visually appealing—yet a skull is also obviously dead, and to some can even seem to look sad due to the downward facing slope on the ends of the eye sockets. A skull with the lower jaw intact may also appear to be grinning or laughing due to the exposed teeth. As such, human skulls often have a greater visual appeal than the other bones of the human skeleton, and can fascinate even as they repel. Societies predominantly associate skulls with death and evil.
