Ars/artes moriendi

Hi, just wondering if anyone knows what these terms mean. Thanks!

Artes is the plural of ars, but it seems unnecessary. Ars moriendi = The art of dying. SS

A search of the Internet will provide thousands of uses of the phrase, but few that reflect its original use in the Middle Ages. One such is on the site: death.monstrous.com/ ars_moriandi.htm

I don't know, but I imagine that's the Ars moriendi you're looking for.
