<P> The most obvious places to look for memento mori meditations are in funeral art and architecture . Perhaps the most striking to contemporary minds is the transi or cadaver tomb, a tomb that depicts the decayed corpse of the deceased . This became a fashion in the tombs of the wealthy in the fifteenth century, and surviving examples still create a stark reminder of the vanity of earthly riches . Later, Puritan tomb stones in the colonial United States frequently depicted winged skulls, skeletons, or angels snuffing out candles . These are among the numerous themes associated with skull imagery . </P> <P> Another example of memento mori is provided by the chapels of bones, such as the Capela dos Ossos in Évora or the Capuchin Crypt in Rome . These are chapels where the walls are totally or partially covered by human remains, mostly bones . The entrance to the Capela dos Ossos has the following sentence: "We bones, lying here bare, await yours ." </P> <P> The danse macabre is another well - known example of the memento mori theme, with its dancing depiction of the Grim Reaper carrying off rich and poor alike . This and similar depictions of Death decorated many European churches . Danse Macabre, Op. 40, is a tone poem for orchestra written in 1874 by French composer Camille Saint - Saëns . </P> <P> Timepieces were formerly an apt reminder that your time on Earth grows shorter with each passing minute . Public clocks would be decorated with mottos such as ultima forsan ("perhaps the last" (hour)) or vulnerant omnes, ultima necat ("they all wound, and the last kills"). Even today, clocks often carry the motto tempus fugit, "time flees". Old striking clocks often sported automata who would appear and strike the hour; some of the celebrated automaton clocks from Augsburg, Germany had Death striking the hour . The several computerized "death clocks" revive this old idea . Private people carried smaller reminders of their own mortality . Mary, Queen of Scots owned a large watch carved in the form of a silver skull, embellished with the lines of Horace, "Pale death knocks with the same tempo upon the huts of the poor and the towers of Kings ." </P>
