Memento mori (Latin for "remember (that you have) to die")[2] is an artistic or symbolic trope acting as a reminder of the inevitability of death.[2] The concept has its roots in the philosophers of classical antiquity and Christianity, and appeared in funerary art and architecture from the medieval period onwards.
The most common motif is a skull, often accompanied by bones. Often, this alone is enough to evoke the trope, but other motifs include a coffin, hourglass, or wilting flowers to signify the impermanence of life. Often, these would accompany a different central subject within a wider work, such as portraiture; however, the concept includes standalone genres such as the vanitas and Danse Macabre in visual art and cadaver monuments in sculpture.
