The most interesting legend states that in Lake Gerundo, very near Milan, an enormous snake lived and terrorized the inhabitants of the city by attacking and eating the children and polluting the water with its venom. In a heroic effort, Ottone Visconti, the founder of the family, slayed the snake and adorned his coat of arms with its likeness as a symbol of triumph.
While this is a highly unlikely legend, not to mention a grim one, it serves to add to the aura around one of the world's most storied and historic brands. A little imagination never hurt anyone - unless, of course, you happened to be a child during the era of terror from the giant snake.
