JFYI, "memento mori" is the motto and also a form of salute between trappist monks, to be picky it is not "remember death" but rather "remember that you will die" which is slighlty different. The origin is to tone down the (eventual) arrogance and pride of the man, it is very similar to "Memento homo quia pulvis es, et in pulverem reverteris " ("Remember, man, that thou art dust, and to dust thou shalt return."): https://en.wikipedia.org/wiki/Ash_Wednesday#Ashes https://en.wikipedia.org/wiki/Ash_Wednesday#Ashes
