[left beneath the miniature holiday tree in the staff lounge (although not too close, because the angel on top has a sword and isn't afraid to use it) for Nate Novarro, from his Staff Secret Santa]
Note attached:
To Mr Novarro, with warmest wishes for the holiday season.
I purchased this device from an antiques shop in Belfast. It was invented by a Squib during the European Inquisition of the 15th century to measure magical energies produced during the casting of spells by witches and wizards. There was not much call for such a thing even then, so it was never popularized and apparently very few remain extant. I thought you might find it of interest in your studies; or at the very least, as a reminder that the unknown may yet be quantified, and all that is wondrous still lies within the realm of discovery.
