[Graves]”Every farm and everywhere.”
I asked my son what he would want done with his remains. His response, “Bury me in a cheap pine box in a cow pasture under an apple tree. That way, when the cows eat the fallen apples, they will be eating me. Only fair, since I’ve eaten enough of them.” Also, of course, as poor farmers and villagers did not make carved stone markers, only a few centuries would eliminate any trace of an organized graveyard. I visited a two centuries old US cemetary, I don’t remember where, but it was a young western settlement. Most of the graves were marked by a simple uncarved stone. Only a few of the later ones had any identifiable marks on them.
And, of course, there have been the many wars and recurring slaughters when there's nothing better to do.
