A skull and crossbones is a symbol consisting of a human skull and two long bones crossed together under or behind the skull.[1] The design originated in the Late Middle Ages as a symbol of death and especially as a memento mori on tombstones.

In modern contexts, it is generally used as a hazard symbol that warns of danger, usually in regard to poisonous substances, such as deadly chemicals.[1]

It is also associated with piracy and software piracy, due to its historical use in some Jolly Roger flags.

In 1829, New York State required the labeling of all containers of poisonous substances.[2] The skull and crossbones symbol appears to have been used for that purpose since the 1850s. Previously a variety of motifs had been used, including the Danish "+ + +" and drawings of skeletons.[citation needed]

In the 1870s poison manufacturers around the world began using bright cobalt bottles with a variety of raised bumps and designs (to enable easy recognition in the dark) to indicate poison, but by the 1880s the skull and cross bones had become ubiquitous, and the brightly coloured bottles lost their association.[citation needed]
