Mitch,
Beautifully made .....and I love the theme !!! Not morbid at all. I believe the most technical translation is "remember you must die". It is really a shortened version of the message offered by my favorite tombstone epitaph from the Middle Ages (or earlier ?), "As you are, so once was I. As I am, so shall you be."
Outstanding work....both the silversmithing and the engraving !!!
