tablesaw | Warehouse 13: Full Inventory—"Resonance" and "Magnetism"

I'm going to go into a bit more detail about the appropriation and misrepresentation of culture and history by looking at the artifacts mentioned in episodes of Warehouse 13. For a brief overview of what I'm talking about in this series, read "An Extraordinary Rendition of History; Items in Warehouse 13 that Don't Belong in "America's Attic". I won't be going into too great detail of research; if I prove something horribly inaccurate, I do so using only minimal Googling. Corrections and clarifications are thus welcome.

I'm doing both together because they're relatively low on things and things to say about those things.

Artifact: Lewis Caroll's Looking-Glass
What does it do? It allows a person to interact with a "double" of some sort, and lets objects pass through to the other side. This is useful for playing table tennis without a partner.
Is it in any way accurate? It certainly seems in line with Caroll's work.
Does it belong in America's Attic? Nope. Like the Brothers Grimm, Caroll is widely read in America, but he himself was English, as were all of his possessions.

Artifact: Mary Queen of Scots' Croquet Mallet (made from a petrified narwhal's horn)
What does it do? "She never lost a match."
Is it in any way accurate? I don't know if the she had such a mallet, but she did apparently play croquet, so that's something.
Does it belong in America's Attic? No, I really can't believe that the UK would let an artifact like that out of its purview.

Artifact: Prehistoric Plant
What does it do? Its pollen can turn a person into a "sexually rapacious sleepwalker" without their knowledge.
Is it in any way accurate? No description of the plant is given, but the effect certainly seems plausible
Does it belong in America's Attic? Several countries are now claiming the rights to intellectual property derived from native fauna (such as drugs made studying plants in the rain forest), but I don't believe that any specifically refuse to let the plants themselves move. (Of course, if the Warehouse moved to eliminate any other traces of the species, there might be a problem.)

Artifact: Antique Camera
What does it do? Turns the subject of the photograph into a monochrome, two-dimensional figure that remains frozen until another picture can be taken.
Is it in any way accurate? We don't see it much, and I don't know from cameras. It looks sufficiently oldish, and
Does it belong in America's Attic? We don't know where the camera's from, but since Artie mentions that he's having a "Kodak moment," I'll assume that it's associated with the American company and/or its founder George Eastman.

Artifact: Eric Marsden's Last Record
What does it do? Produces a state of bliss in the listener that leaves them incapacitated and with short-term memory loss.
Is it in any way accurate? Marsden reads to me like a mix of two geniuses of American pop music, Phil Spector and Brian Wilson. But Marsden is a completely fictional creation.
Does it belong in America's Attic? Marsden appears to be a U.S. citizen who worked in the American music industry. The Warehouse can take it.

Artifact: The Guillotine Blade that Killed Marie Antoinette
What does it do? Unknown, but it seemed to let off a lot of power when the blade came down.
Is it in any way accurate? It's actually easy to find out a lot of information about this very artifact because it's rather famous. It is not on display in France, as Warehouse 13 would have it, but in London at Madame Tussaud's (not that you could tell from their Michael Jackson–soaked website). Here's a picture of it from Flickr. It was purchased by Marie Tussaud's descendants from the descendants of Clément Sanson, the executioner in charge of the machine. The actual blade looks significantly less clean and pretty than the Warehouse blade, and also a bit smaller.
Does it belong in America's Attic? You might think that there might be room for America to claim this artifact, since it's already being kept outside of the nation from which it draws its cultural and historical significance. And yet, you would be underestimating the Warehouse, because in "Magnetism" we see agents of the United States government enter France and steal the blade from a public display, leaving a fake in its place. And I do mean steal, there's lasers and fancy heist gear and everything. And Myka assaults several guards in the process. Given all of that, I have to say no.

Artifact: Little Bell
What does it do? Makes people laugh . . . TO DEATH!
Is it in any way accurate? This only gets a brief mention, so we have no context.
Does it belong in America's Attic? With no context, why not?

Artifact: James Braid's Chair
What does it do? When a person sits in it and listens to a descendant of Braid speak, that person's subconscious impulses emerge and become periodically uncontrollable. It does this by affecting the electrical impulses in the brain, using the metal springs of the chair as a conductor.
Is it in any way accurate? Remember what I said earlier about things being accurate, but with the polarity of accuracy reversed? Yeah, that's what this is. James Braid was a talented surgeon, but he's most known now for his investigation into hypnosis. In fact, he's the person who started using the term "hypnotism" for the phenomenon. Let's listen to him describe why (quoted at Wikipedia):

I adopted the term "hypnotism" to prevent my being confounded with those who entertain those extreme notions [sc. that a mesmeriser's will has an "irresistible power . . . over his subjects" and that clairvoyance and other "higher phenomena" are routinely manifested by those in the mesmeric state], as well as to get rid of the erroneous theory about a magnetic fluid, or exoteric influence of any description being the cause of the sleep.

In other words, Braid is famous because he demonstrated that everything Warehouse 13 says about hypnosis and the brain is wrong and stupid. And while normally it's fine for Warehouse 13 to take fantastic ideas as inspiration, it's really tacky to connect them to the people who were dedicated to debunking them.
Does it belong in America's Attic? Braid was a Scot, not an American.
