  This looks deceptively like the other niches carved in the wall all along
the sides of catacombs, but appears, in fact, to be more.  No corpse resides
here, and instead of wrapped treasures for the corpse to take into the
afterlife, at the head of the indentation there is a small feldspar wall
with a keyhole.  Whoever sanctioned the creation of this niche was obviously
well-connected, as they were able to get it disguised by a permanent
illusion to prevent crypt looting.  Perhaps whatever is behind the feldspar
wall is best left untouched.
