Sum quod eris, fui quod sis.
I am what you will be; I was what you are.

A message engraved on tombstones as a reminder to the living as in the following poem:

Dear Friend,
Forebear and cast an eye.
As you now are so once was I,
As I am now, so shall ye be.
Prepare to die and follow me.

Another person responded with the following words:

Where'er you are, I wish you well;
Whether in heaven or in hell;
But to follow you I can not consent,
Until I know the way you went!
