i've recently was fascinated to know about the jewish 'matzevah's -- old tradition of decorating the entombments.
for example, you may read about it here
https://rohatynjewishheritage.org/en/culture/written-in-stone
and i found a few excellent stories in Russian,

and a hard nut even for me to read:
https://www.diary.ru/~Grabschonheiten/p42612918.htm?oam
a huuuuge, extensive article about symbolic of tombs decoration
not sure if you wanna read it using a google-translator... unless you dig very deep. but at least one can get the impression of how much there's out there...
