AN immediate outburst of creative energy was the result of the victory. Angelo Participazio was chosen Doge and according to precedent associated his son with him. He set himself to enlarge, fortify and embellish Rialto. The ravaged settlements of the Chioggie, Brondolo, Pelestrina and Albiola were rebuilt, and a new Heraclea, called Città nuova, rose on the ruins of the old capital. Dykes were built, rivers diverted and canals bridged. A ducal palace was erected near the Church of St Theodore, and a church to S. Pietro at Olivolo. The Chapel and Convent of S. Zaccaria were founded and endowed by the Doge to contain the body of S. Zaccaria, father of the Baptist, and other relics given to the Venetians by Leo the Eastern Emperor.

There was an old tradition among the early settlers at Rialto that St Mark on his way from Alexandria to preach the Faith in Aquileia was caught in a violent storm and forced to land on one of the Rialtine islands where now stands the Church of S. Francesco della Vigna. As he stepped forth from his bark an angel saluted him saying: “Pace a te Marco Evangelista mio” (Peace to thee Mark my Evangelist), and announced that one day his body should find a resting-place and veneration at Rialto. Traditions like prophecies have a way of bringing their own fulfilment, and in the brief reign of Angelo’s son Giustiniani (827-829) some Venetians trading with the infidels in defiance of imperial prohibition succeeded in stealing the Evangelist’s body and carrying it to Venice. The story of “how the precious body of Monsignor S. Marco came to Venice” is thus told by Da Canale. “Now at this time there was a ship of the Venetians at Alexandria on which were three valiant men. The one called Messer Rustico of Torcello, the other Messer Buono of Malamocco, the third Messer Stauracio; which three valiant men had great hope and devotion to bring the body of S. Marco to Venice, and they so got round (s’en alerent tant autour) the guardian of the body that having won his friendship they said to him, Messer, if thou wilt come with us to Venice and bear away the body of Monsignor S. Marco thou shalt become a rich man. And when he, who was called Theodore, heard this he answered: Sirs, hold your peace, say not so, that may not be in any wise, for the pagans hold it more precious than aught else in the world, and if they espied us would surely cut off our heads. Then said they, wait until the blessed Evangelist command thee. And it came to pass that there entered into the heart of this worthy guardian a desire to bear away the body, and he came back to them saying: Sirs, how can we take away Monsignor S. Marco without the knowledge of any man? And one answered: Right wisely will we do it. And they went hastily by night to the sepulchre where the body was and put it in a basket and covered it with cabbages and swine’s flesh, and they took another body, laid it in the tomb in the very same cloth from which the body of Monsignor S. Marco had been taken and sealed the tomb as it was before. And the valiant men bore the body to the ship in that same basket as I have told of, and for dread of the pagans slung it to a mast of their ship. What shall I tell you? At that very moment when they opened the tomb so sweet and so great an odour spread through the midst of the city that all the spiceries in Alexandria could not have caused the like. Wherefore the pagans said: Mark is stirring, for they were wont to smell such fragrance every year. Nevertheless there were of them who misdoubted and went to the tomb and opened it and seeing the body I have told of in St Mark’s shroud were satisfied. And some there were who came to the ship and searched it about, but when they saw the swine’s flesh by the mast did straightly flee from the ship crying, Kanzir! Kanzir! which is to say, Pork! Pork! Now the wind was fair and strong, and they set sail for Venice and on the third day came by Romania (Greece). And a mighty wind arose by night when the mariners were sleeping, and the ship was driving on to the rocks; but the precious Evangelist awakened the master mariner and said to him: Look that thou set down the sails, for we are making for the land. And the master awakened the shipmen and they struck the sails. And if anyone will know the truth let him come to Venice and see the fair Church of Monsignor S. Marco, and look in front of this fair church, for there is inscribed all this story even as I have related it, and likewise he will gain the great pardon of vii. years which Monsignor the Apostle (the Pope) granted to all who should go to that fair church.”

The Doge and clergy welcomed the body with great ceremony, the traders were forgiven their unlawful voyage, and St Mark became the patron of the Republic instead of St Theodore. A modest little chapel was begun on land acquired from the nuns of S. Zaccaria in the Broglio, which was still a grass-grown field planted with trees bounded by the Canal Battario, which flowed across what is now the Piazza of St Mark. In the next reign the body, which had been temporarily placed in the ducal palace, was solemnly transferred to its shrine in the new chapel of St Mark and Stauracio appointed Primicerio or President of the Chapter.

In 829 Giov. Participazio, the third of the dynasty, began his uneasy tenure of eight years. Obelerio plotted to regain his lost power in Venice, but was foiled and executed, and his head exposed on a stake. A more successful rival was the Tribune Caroso, who worked on popular suspicion of the hereditary tendencies in the reigning family, and drove Giovanni to exile in France. Caroso’s tyranny, however, was a bad exchange for the milder rule of the exiled Doge. The usurper was overthrown and blinded, and Giovanni recalled. But the same jealousy on the part of the people which made Caroso’s coup d’état possible again manifested itself. The Doge was seized as he was returning on St Peter’s Day from the church at Olivolo; his hair and beard were shaven, and he was forced to retire into a monastery at Grado.

Pietro Tradonico, the chosen of the democracy in 836, was much occupied with the pirates who, from their rocky fastnesses in the creeks and bays of the Dalmatian coast, swooped down on the rich Venetian argosies as they sailed the Adriatic. By a first expedition he reduced their chiefs for a while to submission; a second was less happy in its results.

The tide of Saracen invasion was met at Caorle and rolled back, and two great ships of war were constructed to guard the porti. Amid the stress of war the arts of diplomacy were not neglected. A treaty still exists, dated 840, between Lothair, “by Divine Providence Imperator Augustus and the most glorious Duke of the Venetians,” for a period of five years: their relations in peace and war are defined; mutual restitution of runaway slaves is promised, and traffic in the subjects of the contracting powers prohibited; the inviolability of ambassadors and of correspondence assured. Pietro had the honour of welcoming the first royal tourists (855) in the person of King Louis II. of Italy and his consort, who spent three days at Venice. The defeated Participazi were, however, biding their time. In 864 the people’s Doge was assassinated when leaving the Church of S. Zaccaria after Vespers and his body lay on the ground until nightfall, when the pious nuns gave it sepulture in the atrium of their church. The chroniclers record the great wisdom and piety of Orso Participazio, who succeeded the murdered Doge. He cleared the seas of pirates, and sought, by calling a synod of clergy and laity, to purge Venice from the iniquitous traffic in slaves, which continued to stain her commerce. Rialto was made healthier by drainage and building; Dorsodura peopled. The growth of the arts of peace may be measured by the fact that the Venetians were able at this time to make a present of twelve bells to the Greek Emperor. Orso died full of years and honours in 881, and was buried in S. Zaccaria. During the short reign of his son Giovanni a descent was made on Comacchio, a city on the mainland north of Ravenna, whose growing power and commerce roused the jealousy of Venice. The Venetians had long memories, and the help given to Pepin was now avenged by the devastation of the city and the country even up to the walls of Ravenna. In 887 Pietro Candiano, a devout Christian, and a wise and brave prince, was elected, and after a reign of five months met a soldier’s death fighting against the pirates. Pietro Tribuno, who succeeded him, was called upon to face a new danger. In the spring of 900 the Hungarians came down the usual track of the barbarian invaders by the Fruilian passes—“that most baneful gate left open by nature for the chastisement of the sins of Italy”—and ravaged the land. They were held too cheaply by Berengarius, King of Italy, and flushed with victory, spread terror even to the lagoons. The preparations made to resist Pepin were renewed. Rialto was fortified and a castle built on the island of Olivolo, which is called Castello to this day. By the way of the Franks the terrible barbarians overran the outer cities of the dogado, and made for the Porto of Albiola. The Venetian fleet met them, happy omen, at the very spot where Pepin’s might was crushed. A fierce fight ensued, and the battle was again to the islanders. The Hungarians were scattered, and fled, never to return; Pietro was hailed by Berengarius preserver of the public liberty, and was honoured by the Eastern Emperor. Two years later the foundations of the old Campanile were laid in a spot where a great elder tree flourished. At the death of the Doge in 912 the Participazii returned to power.

Orso Participazio II. (912) was a saintly and righteous prince who retired to a monastery after a peaceful reign of twenty years, during which the Venetians obtained from the Emperor Rudolph a confirmation of the right to coin their own money. How great was the expansion of their trade is illustrated in the reign of the next Doge, Pietro Candiano II. (932), who, by the simple expedient of a commercial boycott, brought the arbitrary feudal lord of Istria to his knees. In 942, after a short and uneventful term of power by the rival dynasty, Candiano’s son Pietro became Doge.
