AT THE LINCOLNSHIRE ARCHAEOLOGY MUSEUM: Unique Roman prayer tablet goes on display.
It's a "uterine phylactery," that is, a magical adjuration to protect a pregnant woman. It's made of lead; is tentatively dated to the fourth century C.E.; is inscribed, uniquely, in Latin; and it was excavated in 1994 at the Roman villa in West Deeping. It's not a codex, it's a tablet or scroll, and best of all it's not a fake.
Now you know what a real one looks like.
