In the Middle Ages, however, the Catholic Church undertook a crusade against truffle. It was a dangerous tempter in Aphrodisia and, in addition, it was smelled of sulfur, a sign that it was related to the devil. Nor did Muslims trust mushrooms; a 15th-century Sevillian norm prohibited the sale of truffles around mosques. From the Renaissance, truffles regained their divine status in the kitchen and in the price.
