The Latin phrase memento mori literally means, “Remember that you must die.” The phrase has its origins in ancient Rome, where it is believed that slaves accompanying generals on victory parades whispered the words as a reminder of their commander’s mortality, to prevent them from being consumed by hubris (excessive pride and self-confidence). The concept has become a familiar trope in the visual arts from the medieval period to the present.
In Christian contexts, the memento mori acquired a moralizing purpose, urging the faithful to turn away from fleeting earthly pleasures and focus instead on the afterlife.
