I have learnt that I can blame my grandfather. I never knew him because he died more than 40 years ago. But I am told that he was a passionate, cultured man who loved history, good food and robust discussion. The result was, in the late Fifties and early Sixties, that he ended up driving to Italy every summer with his lover.
It is the lover - now aged nearly 90 - who tells me this. She has told me about the blue Ford Consul motor car, and the roads that were not yet crowded with traffic. He was in his late fifties, she some 15 years his junior.
Their first destination was the aerodrome at Lydd, in Kent, where they loaded their car on to a plane. They were fun, those flights to Le Touquet: after a mere 17 and a half minutes in the air, you arrived in a world that was as exotic as India is today. The first thing my grandfather did on landing was to buy a packet of Gauloise cigarettes. He did it for the aroma, he declared; he did it for France (he had a passion for authenticity).
They then drove off, with the freedom of an entire continent beneath their wheels. Their route through France took them along roads lined with chestnut and walnut trees; they usually crossed the border somewhere above Domodossola, that little mountain village whose syllables so blatantly announce the onset of Italy.
Once there, my grandfather and his lover turned to their trusty guidebooks, two fragile, red Baedekers published in the first decade of the 20th century. These books have since come down to me: bundles of tiny print and exquisitely drawn maps on Bible-thin paper.
Why would my grandfather and his lover have wanted to rely on guidebooks that were 50 years old? Italy was still Italy, I am sure they would have said. The Italy of 1960 was still essentially the Italy of 1900. The intervention of two world wars was no more than a detail. As for me, I cling to the hope that neither of those Italys can be so irredeemably different from mine.
The format of an Edwardian guidebook is surprisingly familiar. Here is the section on how to reach Italy by rail. Here are the sections on conduct, climate and transport. Here are the potted histories, chronologies, introductions to art, maps, and hotel recommendations.
While the books are scrupulously polite regarding the Renaissance, they are less so when it comes to contemporary Italy. Much is made of the "able-bodied loafers" who clog Italian cities; Italian trains are "often, if not, indeed, usually, late". With regard to tips, the traveller is advised "to have no scruple in limiting his donations to the smallest possible sums".
I keep finding slips of paper from between the pages of these books: entry tickets to museums and galleries and theatres in Milan, Vicenza, Padua, Venice, Florence, Ferrara, Rome ... It was a crooked path through Italy that they drove, but its cultured theme is unmistakable.
Florence, I am told, was the city to which they returned with most gusto. And enclosed in the Florence chapter, I have just discovered a bill, from a long-defunct hotel named the Albergo Berchielli, dated September 1962. Four nights, including breakfasts, drinks and laundry, comes to 26,000 lire, equating to roughly £10.
During my own visit to Florence I stayed in a chic, air-conditioned hotel by the Arno that cost £200 per night. How I would love to have crossed the decades, for the sake of a room in the Albergo Berchielli with an iron bedstead, stone tiles and a sink in the corner.
One year, north of Rome, they crashed the Ford Consul into a ditch. His joie de vivre drained away, and she was obliged to step down and knock shyly on the door of a farmhouse. The young men of the family emerged in caps and waistcoats to heave them out.
Later they were exploring the ruins of the Roman Forum, studying the line drawings of the Temple of Castor and the Temple of the Divine Julius. Suddenly they glimpsed a rose among the stones. Today a petal from the same flower, still red after a 45-year pressing in the book, slips down from beneath a map and floats to the floor. I carefully restore it to its place.
They continued south to Naples and Amalfi. One year they even got to Sicily. For us, the foreignness of Sicily in 1960 is impossible to imagine: the bronzed skins of the local youth, the intense light, the pungent aromas, the loudness of the chatter, the power of the priests and of the vulgar, crumbling Baroque and the faint menace of the Mafia.
Soon after crossing the straits of Messina, their camera was stolen from the car. The chances of retrieving it seemed slight. And yet the carabinieri got on its trail: by some miracle, they recovered the camera. The matter was solemnly recorded in the local newspapers, and my grandfather's lover kept all the cuttings.
These cuttings tell the story of a tiny local drama, regarding the lost camera of an English tourist and his lady in Sicily. Here is a grainy old photograph of a policeman. It happened more than 40 years ago, but I will never tire of thinking about it.
THE GRAND TOUR: 10 MUST-SEE DESTINATIONS
1. San Remo
WHY GO? This was a top resort before the Second World War. It's still the place to head to for old-fashioned Riviera glamour. Place a bet at the Art Nouveau casino, an ornate palace.
