In POV-Ray, even a spotlight is technically a point light of sorts; the
light emanates from a single point, not from a diffuse surface or array
of points or something like that. Instead of trying to figure out how to
emulate the Brazil lighting with a plain vanilla light (which will, as
pointed out, put way too much light on the statue) why not just use a
spotlight to begin with?
