Scarcely had the echoes of the music and shouting in the Piazza died away when the gaunt spectre of famine hovered over Venice. The wheat harvest had failed in Europe, the Crusaders had devastated Africa, and she appealed to her allies on the mainland for help. A strong state ever fighting for its own hand may win the respect born of fear, but sympathy, never. The entreaties of Venice fell on deaf ears. Strenuous efforts were made to collect cargoes of corn from Dalmatia, Greece and even Asia. In the nick of time a small consignment came in from Dalmatia and was immediately distributed with absolute impartiality among the people. When the pressure was relieved, a corn office, consisting of three _magistrati delle Biade_, was created to control the corn trade and take measures to prevent any future possibility of famine. The bas-relief in the Ducal Palace, now known as the Cobden Madonna (p. 253), commemorates the wise means adopted by these magistrates in a time of scarcity two centuries later. The coronation oath sworn to by Tiepolo was made even more stringent on the accession of Jacopo Contarini in 1275. The Doge was fast becoming little more than the official mouthpiece of the aristocracy. A clause binding the Doge to keep himself informed of the number of prisoners in the cells at the Ducal Palace and to see that each and every prisoner should be brought to trial within a month of his incarceration, demonstrates how careful the aristocracy were to justify power by wise principles of government. Contarini was an old man of eighty when he accepted office, and after six years retired on an annuity of 1500 lire, the first pension ever granted to a Doge. The steady pursuance of commercial aggrandisement brought Venice in the previous reign into conflict with Bologna. Duties were levied on all ships trading in the ports between Ravenna and Fiume, and a captain of the Gulf of Adria appointed to exact them by force of arms. It was only too apparent that Venice aimed at making the whole Adriatic a Venetian sea, and in 1283 the territories of the Republic in Dalmatia were menaced by a formidable coalition of Aquileia, Ancona, and the Count of Goritz.
