Thanks, a lot. 

The motive of hiding and/or (re-)discovering hidden cultural values, be it money, or texts, or relics is in itself an important research subject. 

Is there any monograph devoted to it?

Dear Artur,

There are any number of Buddhist legends of scriptures found in ruins -- e.g., the tale of the
siddha Maitripa rediscovering the Ratnagotravibhāga in a ruined stūpa.

The subterranean treasures guarded by nāgas and others may also be of interest here.

best,
Matthew
