On the Shores of the Mediterranean

By the time we sailed from Chioggia, the Lagoon, the Litorali, and the Adriatic out beyond them were shrouded in freezing fog, and when we got down at the boat terminus on the Litorale di Pellestrina, which is just opposite the cemetery, and decided to miss the bus connection and take a later one in order to see the murazzi, the sea walls, it was with some regret that we watched its rear lights disappearing into the fog.

The houses in Pellestrina, clustered about a big white church, were a series of rectangles painted in ox-blood, vivid blues and greens and soft greys that rendered them almost invisible in the fog. Closely shuttered against it, as they were, only the drifts of smoke from the strange, tall Venetian chimneys showed that they were inhabited.

Walking amongst them we came to the murazzi, on the seaward side of the Litorale. They had been conceived by a cosmographer, Father Vincenzo Coronelli, in 1716, and work was finally begun on them in 1744 under the direction of Bernardino Zendrini, a mathematician. It took thirty-eight years to complete them at a cost of forty million Venetian gold ducats, and they were the last major works undertaken by the Magistrati delle Acque, the Magistrates of the Waters, who were responsible for building and maintaining the defences of the Lagoon and the city against the Adriatic, before the shameful extinction of this Republic of the Sea by Napoleon in 1797. They replaced previous defences which consisted of wooden palisades that had to be renewed every six years, long groynes extending seawards and musk-smelling tamarisk planted to give stability to what was mostly sand, defences that each winter had been breached and destroyed with monotonous regularity by the sirocco storms. More than 14 feet thick at the base, two and a half miles long, and nearly 20 feet high, they are built of gleaming white blocks of marble, some of them more than 6 feet long and a yard and a half wide, all brought from Istria on the Yugoslavian side of the Adriatic in barges, the same stone used to build so many of the churches in Venice and the Lagoon. Now, ghostly in the fog, they stretched away into it on either side, the only sound the Adriatic sucking at their outer defences, an enormous breakwater of heaped-up boulders.

Although the murazzi are the most impressive to the eye of all the works carried out by the Magistrati in and around the Lagoon, equally important was what they did to the rivers. It was they who were responsible for the death of the Po di Tramontana. Until the sixteenth century the mouth of the river was directed towards the Valle dei Sette Morti, an area of the Venetian Lagoon north of Chioggia, which the river had turned into an area of laguna morta, dead lagoon, only inundated at high tides. They decided, with the presence of mind and self-interest which had always to their rivals been one of the Republic’s least lovable characteristics, to direct the river southwards. In five years thousands of labourers cut a channel, called the Sacca di Goro, from the Po Grande into a bay of the Adriatic east of Pomposa, where the great Benedictine abbey still stands in which Guido d’Arezzo invented the musical scale. By this boldly conceived piece of hydraulic engineering the Po di Tramontana ceased to exist, Venice was preserved and the results for the Po Valley and the Delta were disastrous. The silting process was accelerated and, although the area of the Delta increased nearly three times in the space of 220 years, the inundations increased and no one, except the Venetians, was better off.

But in spite of their success in turning away from the southern part of the Lagoon and finally destroying the Po di Tramontana, they were still subject to the recurrent nightmare that the same silting-up process might happen further north in the part of the Lagoon in which the city stood and deprive it of the isolation on which it depended for at least part of its power and importance; it might also block the vital channels to the sea.

The Republic had before it the awful examples of other great ports in the Mediterranean, long since silted up and left far from the sea, all of which we were subsequently to visit in the course of our travels: Pergamum, Ephesus, Miletus, Patara, the high and dry port of Xanthus in Lycia, in western Asia Minor. And much nearer home they had the equally awful example of Ravenna, a former lagoon city, dependent for its continued existence on tidal movements, acquired by them but only long after it was high and dry, the only memorial to its former Byzantine greatness five splendid churches in the wilderness. And there was also Ferrara, founded on the right bank of the Po in AD 450 by refugees from Attila and his Huns, left equally high and dry.

In the seventeenth century the Magistrati re-routed a number of other rivers so that instead of flowing into their lagoon, they by-passed it completely and flowed into the sea. When the Venetians had finished this colossal work, the Brenta, which originally came out into the Lagoon behind Venice, entered the Adriatic south of Chioggia; the Sile, a very pretty little river which, nevertheless, was doing enormous damage to the Lagoon by pouring silt into it north of the city, was directed into a canal which carried it into what until then had been the bed of the Piave and into the sea near Jesolo; while the Piave itself was turned into the bed of the next river to the north of it, the Livenza.

Later that afternoon we descended from the No. 11 bus on the Litorale di Lido and groped our way through the fog to a dark, deserted waterfront behind the Casino, which faced the Lagoon. It is difficult to write feelingly about something you can’t see, and the fog that shrouded the Lagoon was impenetrable. In fact we could hear more than we could see of it: the melancholy crying of gulls, the tolling of a bell mounted on a buoy moored out in one of the channels, the noise of boat engines and, occasionally, angry cries as helmsmen, set on collision courses, recorded near misses. Altogether, with the whole of the Mediterranean to choose from, it was a hell of a place to end up in on such a day. We might just as well have been on the Mersey, for all the genius loci I was able to sop up, and this made me think of home, a hot bath and a couple of slugs of Glenmorangie.

‘You’re in trouble, author,’ said Wanda, my companion in life’s race, near the mark as always, sensing that I felt like emigrating back to Britain, ‘if you can’t see what you’re looking at.’

As she said this, as if to show that she wasn’t always right, the fog lifted, not everywhere, not over Venice itself which remained cocooned in it, but here and there, and for a few moments that didn’t even add up to minutes we found ourselves looking down long corridors of vapour illuminated by an eerie yellow light that must have been the last of the setting sun, down which one had distant prospects of mud banks uncovered by the tide, with labyrinths of channels running through them, and one or two of the almost innumerable islands of the Lagoon which supported until quite recently – and some still support – monasteries, nunneries, forts, miniature versions of Venice, a cemetery, and the lonely enclosure to which, once every ten years when it begins to fill up, bones are taken; fishing settlements, lodges used by the wildfowlers who in winter wait in barrels sunk in the Lagoon for the dawn and dusk flights, quarantine stations, lighthouses, hospitals, lunatic asylums, prisons, barracks, magazines that, when they were full of gunpowder, had a tendency to go up in the air, taking their custodians with them, deserted factories, old people’s homes, private houses, market gardens, vineyards, and some that were just open expanses that a farmer might visit once or twice a year to cut the hay. The channels among them were marked by long lines of bricole, wooden piles either driven into the bottom with their heads pressed together, as if they were lovers meeting in a lagoon, or else in clusters of three or four, also with their heads pressed together as if they were conspirators discussing some dark secret. Some of the more important channels had lights on the bricole. Some that were only navigable by the smallest sorts of craft, such as gondolas and boats called sandali, were indicated by lines of saplings.

There was another, equally momentary vista of part of one of the industrial zones that had been created by filling in vast areas of the northern part of the Lagoon and its mud flats, a huge, nightmare, end-of-the-world place without houses or permanent inhabitants, made up of oil refineries, chemical, fertilizer, plastic, steel, light alloy, coke, gas and innumerable other plants all belching dense smoke and residual gases into the sky and effluents into the Lagoon, so various and awful that collectively they made up a brew that even to a layman sounded as if it had been devised by a crew of mad scientists intent on destroying the human race, which in effect is what they are doing. Then the fog closed in again, more impenetrable than ever now that the sun was almost gone.

According to the tide table I had bought that morning in Chioggia it was now just after low water at Porto di Lido, what had been the principal entrance to the Lagoon and to Venice when it was commonplace to see 60,000-ton tankers wandering about in St Mark’s Basin. This was until they dredged the deep-water channel from Porto Malamocco to Marghera, using the material brought up from the bottom as infilling for the Third Industrial Zone. About now the flood would be beginning to run through Porto di Lido, Porto di Malamocco, and also through Porto di Chioggia, the three entrances that the Magistrates of the Waters had left open centuries ago, having sealed off the others after years of trial and error, by doing so preserving a delicate balance which allowed Venice to function both as a city and a great seaport. Now, for six hours, the tide would flow into the Lagoon, which is not what it appears to be – a single simple expanse of water – but is made up of three distinct basins, each separated one from the other by watersheds known as the spartiacque, spreading through its main arteries and myriad veins, channels so small that no chart shows them, and scouring and filling the canals of the city itself. Then, at the end of the sixth hour, when it was at the full, the tide would begin to run out, loaded with the effluent of the industrial zones, which sometimes includes dangerous quantities of ammonia and its by-products of oxidation, phenol, cyanide, sulphur, chlorine, naphtha, as well as oil from passing ships and boats, all the liquid sewage of Venice, the peculiarly filthy filth of a city entirely without drains, a large part of the solid ordure produced by its inhabitants, and at least a part of that produced by Mestre and Marghera, together with vast quantities of insoluble domestic detergent. One of the more awful sights in the Lagoon used to be a mud bank at Marghera with mountains of ordure rising from it, preserved, presumably for all eternity, or until they burst, in plastic bags. There they waited for an exceptionally high water, an acqua alta, to distribute them over other distant parts of the Lagoon, with thousands of gulls, apparently unable to penetrate them with their beaks, hanging frustratedly over them. All because a large incineration plant, built in the Second Industrial Zone, failed to work.

Twenty years ago the only fish of any size that was indigenous to the Lagoon and which reproduced itself in it was something called the Gò (Gobius ophocephalus), which nested in the mud on the edge of the deep canals. All the others were caught in the open sea and penned in the valli at the northern and south-western ends of the Lagoon. Mussels were also cultivated. Whether it is safe to eat any of these fish today must be questionable. There is no need any more for the Commune to display the warning against swimming on the door of the crumbling open-air swimming place on the Zattere, the long waterfront in Venice facing the Giudecca Canal. It is only too obvious.

The Adriatic performs this operation of filling and emptying the Lagoon four times every twenty-four hours over an area that used to be roughly thirty-five miles long and up to eight miles wide, but is now much less because of infilling and the construction of new valli. That is except during periods of what Venetians call la Colma or l’acqua alta, high water.

Even though the moon was nearly full there would be no acqua alta on this particular night. Acqua alta is not dependent on the tide itself being exceptionally high, or even high. It occurs when the barometric pressure falls sufficiently low to allow the level of the Adriatic to rise on what is a very low coastline, and when the strong, warm, south-westerly sirocco blows up it. If the barometric pressure is low enough and the sirocco is strong enough at the time when the ebb is beginning in the Lagoon, the water is penned inside it, unable to get out, and when the next tide begins to press in through the three entrances, the Porti, and is added to the high water already there, the natural divisions between the three basins of the Lagoon, the spartiacque, cease to exist and Venice and many other islands, inhabited and uninhabited, are flooded. Other factors can make the acqua alta even higher – heavy rain, a full moon, something called the seiche, the turning of the Adriatic on an imaginary pivot – but the sirocco and a low barometer are the two indispensable conditions.

This is not a new phenomenon. The records of the acqua alta from the thirteenth century onwards are full of entries such as ‘the water rose to the height of a man in the streets’ (on 23 September 1240); ‘the water rose from eight o’clock until midday. Many were drowned inside their houses or died of cold’ (in December 1280); ‘roaring horribly the sea rose up towards the sky, causing a terrible fear … and with such force that it broke the Lido in several places’ (in December 1600).

In 1825, the murazzi, neglected since the fall of the Republic in 1797, were breached during an enormous storm, but were made good again. On a day in 1967, the first year in which accurate measurements were kept, the water rose five feet above the average sea level. In the forty-seven years between 1867 and 1914, only seven exceptionally high waters, those more than three and a half feet above the normal level, submerged the city; but in the fifty years between 1917 and 1967 Venice sank beneath the waves more than forty times, an extraordinary increase, so that looking at a vertical graph of these high waters during the period from 1867 to 1967 the lines representing them appear as eight more or less isolated trees between 1867 and 1920, some thick clumps in the thirties, late forties and early fifties, and a dense, soaring forest in the late fifties and sixties. The longest line of all is the one showing the acqua alta of 4 November 1966.

During the night of 3–4 November, the sirocco blew Force 8, the barometer fell to around 750 mm, there was continual heavy rain and waves twelve feet high roared in over the Litorali, submerging Cavallino, the northernmost one, smashing the elegant bathing establishments on the Lido and hurling aside the outerworks of the murazzi on Pellestrina, the great boulders piled fifteen feet high, then breaching, in ten different places, the walls themselves, composed of huge blocks of marble six feet long, but on which no proper repair work had been done for more than thirty years. This time the water at Venice rose six and a half feet above the average sea level, and the result was spectacular.

It poured under the 450 or so bridges (scarcely any Venetians, let alone outsiders, agree about the number of bridges in the city, or any other of the following figures), overflowing the 177 – some say 150 – canals, the rii, 46 of which are branches off the Canalazzo, the Grand Canal, inundating the 117, or 122, or whatever number of shoals or islands on which the city is said to be built, the 15,000 houses in which large numbers of people were living on the ground floors in the six sestieri, or wards, into which it is divided, and the majority of the 107 churches, of which 80 were still in use. It also inundated 3000 miles of streets and alleys, the various open spaces, the campi, so called because they were once expanses of grass, the campielli and the piazzette, not to speak of the only Piazza, St Mark’s, with an unimaginably vile compound of all the various effluents mentioned previously in connection with the Lagoon. To which was added diesel oil and gas oil which had escaped from the storage tanks, leaving the city without electric light, means of cooking or heating, or any communication with the outside world, not to speak of the awful, immense, much of it irreparable, damage done to innumerable works of art.

The acqua alta persisted for more than twenty hours. The most dangerous moment came at six in the evening, when the water reached the highest level ever recorded. This was the moment that the Venetians call the acqua morta, when it should begin to go down but doesn’t. By this time the glass was down to 744 mm and if at this moment a fresh impulse had been given to the waters by the sirocco, forcing it to yet higher levels, Venice might well have collapsed. As it was, a miracle occurred. The wind changed. It began to blow from the south-west, a wind the people of Venice and the Lagoon call the vento Garbin, and by nine o’clock that night the waters began to fall and the city was saved, at least for the time being.

Long before we stepped ashore from the steamer on to Riva degli Schiavoni, the great expanse of marble quay off which Slavs from the Dalmatian coast used to moor their vessels in St Mark’s Basin, darkness had added itself to the fog, creating the sort of conditions that even Jack the Ripper would have found a bit thick for his work down in nineteenth-century Whitechapel.

The fog dissipated what had seemed a romantic possibility when we left Chioggia but now seemed a crazy dream, that we might sweep into Venice from the Lido on the No. 11 steamer up the Canale di San Marco and see the domes and campanili of San Giorgio Maggiore and Santa Maria della Salute not as we had seen them once, coming in from the sea in the heat of the day, liquefying in the mirage, then reconstituting themselves again, something that would be impossible at this season, but sharply silhouetted, appearing larger than life, against the afterglow of what could equally well be a winter or summer sunset, with what would be equally black gondolas bobbing on the wine-coloured waters in the foreground. This was a spectacle we had enjoyed often, usually in summer, coming back after a long afternoon by the lifeless waters of the Lido with sand between our toes and stupefied with sun, our only preoccupation whether we would be able to extract enough hot water from the erratic hot water system in our equally decrepit hotel to allow us to share a shallow bath; and whether we could find another place to eat, in addition to the few we already knew, which was not infested with, although we hated to admit it, people like ourselves, fellow visitors to Venice who on any day in the high season, July and August, probably outnumber the inhabitants.

Never at the best of times a very substantial-looking city – even the largest buildings having something impermanent about them, due perhaps to the fact that they have not only risen from the water but, however imperceptibly to the human eye, are now in the process of sinking back into it – on this particular evening the fog had succeeded in doing what the mirage could only accomplish for a matter of moments – caused it, apart from its lights, to disappear from view almost completely.

Disembarking from the steamer, we turned left on Riva degli Schiavoni, passing the entrances to the narrow calli which lead off from it, Calle delle Rasse, where the Serbian material used for furnishing the interiors of the felzi, the now largely extinct cabins of the closed gondolas, used to be sold, and Calle Albanesi, the Street of the Albanians, down which some of our fellow passengers had already vanished. While walking along the Riva we just missed falling into what is, because it is spanned by the Bridge of Sighs, the best known and most photographed canal in Venice after the Grand Canal, the Rio Palazzo. This would have been a bore because besides contracting pneumonia (our luggage was already at the railway station), if we had inadvertently drunk any of it we would have had to rush off to the Ospedale Civile, San Giovanni e Paolo, in order to have pumped out of us a mixture the smallest ingredient of which was water. Then we crossed the Rio by the Ponte di Paglia, passing on our right hand the Palazzo delle Prigioni, from which the magistrates known as the Signori di Notte al Criminale used to look out at night for evil-doers, malviventi, arrest and try them, and if they were sufficiently low and common and criminal, sentence them to the Pozzi, otherwise the Wells, the cells at the lowest level of the Prigioni, which were reserved for the worst sort of common criminals.

Then on along the Molo, the furthest point pirates ever reached when attacking Venice, back in the ninth century when it was young, past the forest of piles where the gondolas were moored, now, in this weather, all covered with tarpaulins, as they would be in the Bacino Orseolo, the basin behind the Piazza San Marco where there is another big fleet of them moored. For no one on a day like this would have used a gondola, unless they were sposi, newly married, or were dead and being conveyed in a funeral gondola to Isola San Michele from one of the undertakers’ establishments on the Fondamenta Nuove. In fact, today, scarcely anyone goes to the cemetery in one of the old funeral gondolas, which were picturesquely decorated with a pair of St Mark’s lions in polished brass; now the undertakers’ boats are almost all big, powered vessels.

Then we turned right into Piazzetta San Marco, with the Palazzo Ducale on one hand and the Mint and the Library designed by Jacopo Sansovino on the other, passing between the feet of the two immense grey and red granite columns that someone had brought here from Syria or Constantinople. Somewhere overhead, invisible in the fog, the grey column supported the bronze lion, really a chimera, a fire-breathing monster with the head of a lion, the body of a goat and the tail of a serpent, whether Etruscan, Persian or Chinese no one really knows, to which some inspired innovator has added wings. The other bears a marble figure poised on a crocodile, said to be that of Theodore, the Greek saint who was the patron of the Veneto until the body of St Mark arrived in such a dramatic fashion in the city (having been hastily cleared through customs in Alexandria by Muslim officials who had been told he was a consignment of pork). In fact the statue is not one of St Theodore at all, but is made up of several pieces from the ancient world, the topmost part being a magnificent head of Mithridates, King of Pontus. The statue is a copy. The original is in the Palazzo Ducale.

We entered the Piazza, described by Napoleon, in a rare lighthearted mood, and with reason, as the ‘finest open-air drawing room in the world’, an immense open space, originally paved with bricks, now covered with black trachyte, a fine-grained volcanic rock of rough texture, from the Euganean Hills near Padua, ornamented with narrow inserts of white Istrian marble. The design, made by Andrea Tirali in 1723, forms a pattern of interconnecting squares and rectangles, punctuated by white dots on the black background, so that from the belfry of the Campanile high overhead, the Piazza looks as if two parallel rows of black and white carpets have been laid end to end in it on top of a large, black, fitted carpet, for the reception of some distinguished personage.

Although a superficial glance gives one the impression that it is rectangular, the Piazza is a trapezoid, a quadrilateral having neither pair of sides parallel, and is more than thirty yards wider at its eastern than at its western end.
