Lord Rama killed Vaali,who was fighting his brother Sugreeva,by hiding behind a Tree.
Vaali and Sugreeva were visible to Him , but not Rama to Vaali or Sugreeva.
This is the description by Valmiki in the Ramayana.
Can one recreate this on Stone exactly as described by Valmiki?
Yes this Sculpture is in Darasuram, Irawadheswarar Temple near Kumbakonam.
One can not see Rama from the pillar where His sculpture is, the pillar where the Sculpture of Vaali and Sugreeva are fighting.
But from the pillar where Rama’s sculpture is the fighting of Valli and Sugreeva are visible.
The sculptures are so vivid in detail one can see the Bows strings .
Readers form Darasuram, Kumbakonam may contribute more on this, specifically the Pillars.
