Venice was a sacred text to be read and meditated. In the fourteenth and fifteenth centuries the city was first seen as a totality, to be carefully structured. It had survived, by the exercise of the divine will, and now had to be sculptured. The body of Saint Mark, supposedly preserved in the basilica, was the central point of the configuration between the ducal palace, the market and the Arsenal. This was the sacred geometry of Venetian power.
It is noticeable, in Venetian painting, that the miracles of the Scriptures often take place in a Venetian setting. For Tintoretto the events of the New Testament were seen as an aspect of familiar Venetian life. In a manual of devotion written for young Venetian girls, the
It was itself a city of miracles. No city in Europe, with the possible exception of Rome, has witnessed so many. Every parish had its own sacred events. The compiler of the
Carpaccio painted “Miracle of the Relic of the True Cross on the Rialto Bridge” when a lunatic was healed by the presence of the relic. There was the miracle at S. Lio in the early years of the fifteenth century, when in the parish of that name a holy relic would not be associated with the funeral of a wicked man. It grew so heavy that it could not be carried over the threshold of the church. Giovanni Mansueti completed a painting of the event in 1494. It is still possible to recognise the site, and certain of the larger houses, in 2009. That is another Venetian miracle.
The sacred sites of Venice can be enumerated. The first of them, by common consent, must be the basilica. It is the umbilicus, the central point, the core. It is the place where the divine and human meet. In the beginning there had been another church on this site dedicated to Saint Theodore but, when the supposed body of Saint Mark arrived in the lagoons, everything changed. As soon as the relics arrived in 829, a church with a wooden roof or dome was raised on the model of the church of the Holy Apostles in Constantinople. The church was largely destroyed by fire in 976, but was subsequently restored. The final reconstruction, vaulted and built in brick, assuming the shape of the basilica still before us, was undertaken in the second half of the eleventh century. The fact that it was based upon a model already five hundred years old was a material blessing. It emphasised the supposed antiquity of the Venetian religious tradition. The city had no true religious history of its own; so it borrowed or adapted what it saw. The undulating pavement of the basilica, for example, was not an accident or a mistake. It was deliberately modelled on the floor of the church of S. Giovanni Evangelista in Ravenna, built in the fifth century. The pavement was to rise and fall “as if agitated by winds and to present the likeness of a storm.” It was supposed to invoke the position of Venice upon perilous waters.
In the thirteenth century a programme of mosaics was formally introduced, taking their example from the church of the Holy Apostles but introducing specifically Venetian motifs. These in turn were erased, restored only in the seventeenth century. In the fourteenth century the façade of the basilica was partially transformed in Gothic style. So the church arose by a process of accretion and accommodation, encrusted and adapted over the centuries. Marbles and statues—bought or stolen, it made no difference—were attached to it in almost haphazard fashion.
