Skull and crossbones (Spanish cemetery)

Actual skulls and bones were long used to mark the entrances to Spanish cemeteries (campo santo). The practice, dating back many centuries, led to the symbol eventually becoming associated with the concept of death. Some crucifixes feature a skull and crossbones beneath the corpus (the depiction of Jesus' body), in reference to a legend that the place of the crucifixion was also the burial place of Adam or, more likely, in reference to the New Testament statement (King James Version: Matthew 27:33, Mark 15:22, and John 19:17) that the place of his crucifixion was called "Golgotha" (tr. "the Place of a Skull").
