Light and the visual sense

[Berengar]

@eldarin

Hi,

I wonder if blocking light and blocking sight are a single or separate properties of stone.

I.e. can I have a room or building that has no windows, cast PeTe to destroy the property of stone that blocks light but not the property that blocks visual species and have a well illuminated place?

A recent one of several discussion of invisible objects on this forum is here and refers to this. It starts from

@"HoH:S p.61 [i

Species[/i]"]Iconic species are carried in light, and are interpreted by the eye.

A stone not blocking light/lumen would in general hence not block the species carried in it.

But could it be made to do so with PeTe? That change to the stone would be less about the stone (transparent/intransparent) than about the species carried in the light/lumen passing through it. So this is unlikely to succeed with PeTe.

Could it be made to do so with MuTe changing the stone into something highly unnatural? That looks like just changing a stone into something doing something highly unnatural - stripping species - to something unrelated - namely the light/lumen - just passing through the stone. Couldn't you, by following this pattern, then MuTe a stone into something doing just about anything to objects it touches? Best ask your troupe - but I wouldn't permit it.

Cheers

EDIT: It is possible to change stone to semitransparent milk glass. This cannot be seen through, but still lets part of the light pass. Such glass is known since antiquity: look up e. g. the Lycurgus Cup to get further ideas.
