Weep Not For Me, My Friends So Dear

Weep not for me, my friends so dear
I am not dead but sleeping here.

Sylvester Cox

There are many variants of a poem which starts with the lines from this epitaphs. It is even quoted in a 2006 book, called the beautiful City of the Dead, but there is no clear author identified.
Here is one expanded version of the poem.
“Weep not for me, my friends so dear.
I am not dead, just sleeping here.
My grassy bed, my grave you see.
Prepare in life to follow me.
