Another time traveller, John Bentley, was imprisoned by some armed Spaniards after they witnessed his time machine's materialisation and thought him to be practicing witchcraft. A tribunal of Inquisitors interrogated him, trying to get him to admit that he "wasn't human" but rather a sorcerer. Bentley managed to escape by claiming that if they allowed him to get back inside his "cabinet", actually the time machine, he could help them find many other sorcerers — and, naturally, leaving the time period as soon as he was inside.
