And indeed the apparent size. There was certainly no suggestion that it was in any way an "ordinary celestial body", which is what you're apparently proposing, or erroneously assuming to have ever been the case.

And as I say, have you any evidence for this claim? I can think of none.

Are you implying that's what I'm doing? That would be a wholly unwarranted characterisation; I suggested no "patch" to the searchlight model, I merely pointed out why your model was a) not 'the old model', and b) has its own issues with consistency of explanation. The 'searchlight model' proposes that in each 'septant' of the mundane world one sees a progression from black to crescent to half to full moon, and so on; supposing you'd see something else, requires an appeal to optics on your part that you're accusing the proponents of the idea of making. (_Why_ you'd see such a thing is another matter, and I make no suggestion on that.)

What one'd see in Silver Shadow is another matter again, but it might be well to get some rather more basic issues straight before venturing too far down that line of thought.

Optics and astronomy are rather different matters. And either comparison still seems to me to be mistaken: the 'searchlight model' is nothing much at all like the behaviour of our moon (your suggestion would be much moreso), and it assumes nothing at all like RW optics.

I agree that 'bendy light' is a horrible account, but are you seriously suggesting that Glorantha ought to simply not to have a horizon? I suppose this comes down to whether one thinks Glorantha is a place where mythic accounts are compellingly true, or one with assorted cheesy magical special effects to underpin the idea that it ultimately has nothing at all to do with our world. (Discworld with more fights between the jokes, to heavily paraphrase the old saw about ice hockey?)
