Please read the lines given below:Could you please explain the lines in bold to me? What is the writer trying to say?
I am sitting on a tomb, and when the time comes to piss again, I have my pick. Or I wander, hands clasped behind my back, among the slabs, the flat, the leaning and the upright, culling the inscriptions. Of these I never weary, there are always three or four of such drollery that I have to hold on to the cross, or the stele, or the angel, so as not to fall.Mine I composed long since and am still pleased with it, tolerably pleased. My other writings are no sooner dry than they revolt me, but my epitaph still meets with my approval. There is little chance unfortunately of its ever being reared above the skull that conceived it, unless the State takes up the matter.But to be uneatrhed I must first be found, and I fear those gentlemen will have as much trouble finding me dead as alive. So I hasten to record it here and now, while there is yet time:
Hereunder lies the above who up below
So hourly died that he survived till now
Thanks in advance
