[Snow White] Is the Evil Queen's beauty natural, or a result of her witchcraft?
gpt
Her beauty is wholely unnatural. In these tales, good and beautiful are always synonymous, as are evil and ugly, but Snow White's stepmother (the most evil of relatives) clearly goes against all known laws of nature by being both very beautiful and evil.

I would like to propose that it is the result of a spell that she had cast a long time ago, one that she couldn't reverse or update. The spell was likely to be the fairest person in the world, but she had later learned that it was conditional only at the time the spell was cast. That would give her reason to require the magic mirror and the daily ritual of asking it who the fairest of all was.

\*Note: This is for the 1819 Grimm's version and it's progeny. There are other versions, including Grimm's original in 1812, where the Queen is Snow White's mother, which could lean towards the other side since pretty people tend to have pretty kids.
