Memento mori (Latin: 'remember that you will die') refers to artistic and literary symbols or objects intended to remind the viewer of the inevitability of death. The tradition is ancient — Roman generals at triumphs were followed by a slave repeating 'memento mori' to prevent hubris. In medieval art, the memento mori appears in the 'danse macabre' (Dance of Death), where skeletons lead men of every rank to their graves, and in depictions of the Three Living and the Three Dead. In Renaissance and Baroque painting, it takes the form of Vanitas still-life symbols: skulls, hourglasses, snuffed candles, wilting flowers. The Romantic era produced a more melancholy relationship with mortality: graveyards, ruins, autumn landscapes as meditations on time. Today memento mori appear in tattoo culture, in Damien Hirst's diamond skull, and in any art that directly addresses death.
