In a more innocent age, it was said that Gregory Efimovich Rasputin's legendary power over women was due to his piercing eyes.

But a new museum of erotica here suggests that the mad monk's charm may instead have been, ahem, concealed beneath his cassock.

Measuring 28.5cm (about 11 inches) - allowing for shrinkage caused by pickling - Rasputin's penis displayed in a tall glass bottle is, to put it delicately, a big attraction at the museum.
