Broken rocks. What should I do here ?

[solid grotto]

I saw this broken rocks. If I press Q, it will glow.
I thought its like another thing that I can interact with and it became statue.
But this one, there is no interaction prompt. What should I do ?

[hollow lintel]

i think that specific statue is used during the torment stag fable and can only be interacted with at a certain point during that fable
outside of it, it doesn't really have a function
