Graffiti from 1835.
Once again we've been shown something different on our last visit to the mushroom caves at Bourré. Above is some graffiti showing a man with a bucket, three horses and riders, a rooster and another man holding two vessels. The text translates as '1835 done 14 February one thousand eight hundred thirty five by Julien(?) Biett(elle?)'.
The photo below shows a grid with numbers. The guide told us it was a tally of mushrooms (presumably harvested).
