Northern Italians often speak of Sicily as a Saracenic darkness — the place where Europe ends. The Arabic influence remains strongest in the Mafia-infiltrated west of the island, where the sirocco blows in hot from the deserts of North Africa. When the Arabs invaded Sicily in 831 they introduced mosques and pink-domed cupolas, as well as the sherbets and jasmine-perfumed ices for which Sicily is renowned.
