In the summer of 1818, the French novelist, Stendhal, visited the 500-ft deep salt mines outside Salzburg. For the duration of the trip, he was accompanied by a beautiful brown-eyed Italian lady called Madame Gherardi. Upon arriving in the city, they made the acquaintance of a charismatic Bavarian officer. He was invited to join their budding tour group and quickly fell deeply in love with Stendhal’s enchanting companion.
