This is the Oxford University Museum Natural History, which in itself is fairly interesting (Look at all the dinosaurs!), but the museum I'm talking about is the Pitt Rivers museum. It's tucked away at the back of the natural history museum, and you might miss it if you don't know it's there. Trust me. This one is worth seeing. And, best of all? It's completely free! Not in Oxford? There's a virtual tour you can check out.
When you enter Pitt Rivers, you see a gorgeous old Victorian hall full of glass cases holding all manner of strange and fascinating objects from shrunken skulls to Japanese Noh-theatre masks. This place is a treasure trove of story ideas. I took lots of photos of objects that set off that story tingle in my head, and here's a few of them. Enjoy.
A Russian moss figure.
Steampunky rifles, no clockwork, though.
Gorgeous model ship.
A bird mask from Columbia. They were used in rituals to get rid of disease, if I remember correctly. This reminds me of those medieval plague masks people stuffed with herbs to protect themselves from getting sick, and also the Songbird in Bioshock Infinite. (Cool game, seriously weird ending, btw.)
