Stumbled upon this weirdness a couple days ago, thought it might be relevant to our Y symbolism.
In contemporary culture, Perchta is portrayed as a "rewarder of the generous, and the punisher of the bad, particularly lying children". So like an Austrian Santa? More like the stuff of nightmares if you ask me.
