“I have seen the future and it works,” said Lincoln Steffens, a left-wing American journalist, on returning from the Soviet Union in 1919. After a weekend in Venice at a seminar organized by the Italian ambassador to Britain, I found myself struck by the same thought, which is not exactly the reflection that the world’s most perfectly preserved medieval city is supposed to inspire. Venice is a clichéd metaphor for “Old Europe” — a sclerotic old continent fixated on its past and now retiring to become a museum society, destined gradually to sink beneath the sea. But should we perhaps be inspired, not depressed, by the thought of Venice, the ultimate “museum city,” as a microcosm of Italy and even of Europe as a whole? After all, Venice is still standing, not sinking into the sea, and after 500 years of supposed decline it is still stunningly beautiful. Maybe Italy and Europe, instead of sinking, will also prove their resilience and make a comeback?
