At the close of one of these Ascension ceremonies, in 1622, there was a violent earthquake in Venice. Just as the doge and his courtiers returned from their voyage of celebration, a slow and regular thunder beneath the earth lasted for several seconds. Everything trembled but nothing, apart from a chimney, fell. There have been other quakes in the lagoon. It is an unstable area in every sense. An earthquake is recorded in 1084, when the campanile of S. Angelo was dislodged. Towards the end of the twelfth century there were simultaneous upheavals in Saint Mark’s Square and on the island of Torcello, suggesting that there is a “fault” lying between them. There was a great earthquake on Christmas Day 1223, and then again in 1283 when the shock was followed by a great inundation. On 25 January 1384, another earthquake set all the church-bells of Venice pealing at the same time; it was followed by another shock on the following day, and these quakes were repeated at intervals over an entire fortnight. The Grand Canal was empty, but the streets were full of water.
The weather of Venice is sea-weather; the air is damp and salt-laden, conducive to fog and mist. If the climate is equable, that may in part be the position of Venice. Averroes, the twelfth-century philosopher, was the first to calculate that Venice was at a latitude of forty-five degrees, at the middle point between the equinoctial and the northern Pole. It is another example of the extraordinary balance of Venice between the geographical regions of the earth. The climate is mild, compared with much of North Italy, because it is environed by the sea. The spring is delicate and fresh, the energetic wind blowing from the Adriatic. The summer can be sultry and oppressive but, once the sun has gone down behind the Friulian mountains, the air is freshened by the breezes from the sea. The autumn is the true season for Venice. It has an autumnal air, the air of melancholy and departure. The Venetian painters, Carpaccio and Bellini, bathed their canvases in an effulgent autumnal light.
There is, especially in autumn, the possibility of rain. A subdued greyness then haunts the air, and the sky is the colour of pearl. The rain can be persistent and torrential. It soaks through the most protective clothing. It can be blinding. Then the rivers may burst their banks, and the rising waters around Venice turn to a jade green. The best description of the Venetian rain is found in Henry James’s
The “wicked wind” may come from several points. An east wind blows in from the sea, refreshing in the warmer months but crueller in the colder seasons of the year. A wind from the north-east, the
There are gusts of wind that pass very quickly, and eddies or squalls of circulating air. Sir Henry Wotton wrote of “flashing winds.” All this is of the nature of the sea. There is a south-westerly wind, too, once called
But the most celebrated wind is the
