The first bishop was appointed to Ariminium as early as 260, and ninety-nine years later the celebrated council of the Arians and Athanasians met to deliberate over their differences in the city. In the sixteenth century, when it formed part of Otho III.'s empire, a Malatesta was appointed viceroy of Le Marche, and the long connection of this family with Rimini then commenced. The most renowned member of the "Wrong-heads" was undoubtedly Sigismondo, a man of great ferocity of disposition and licentious in his habits. Like many another bellicose noble, Sigismondo had two sides to his nature, and whatever his faults, it is to his credit that many of his leisure hours were spent in the company of philosophers and men of pacific tastes. It is due to his patronage of Art that the genius of Leo Battista Alberti, another curious and complex product of the age, found scope in the great church of S. Francesco. We owe to these two men--one the patron, the other the architect--the best example of transition from Gothic to Renaissance which Italy possesses.
The cathedral, a Gothic edifice dedicated to S. Francesco, was but one hundred years old when Sigismondo set Alberti to work on its transformation. Malatesta undoubtedly intended it to be the mausoleum of his race, and that is what this most unecclesiastical building, which is called the Tempio di Malatesta, is. The façade is extremely simple. It is spaced out into three equal divisions. The centre is occupied by the portal which has a good pediment and a round arch borne by highly ornate pilasters. On either side are four Corinthian columns supporting the three flat-membered arches of the façade. Over them is a broad frieze. The bases of these columns stand on a very beautiful course which is continued round the two sides of the Tempio. At intervals, amidst finely-chiselled heraldic roses and little elephants, are alternating shields bearing the I and S of Isotta and Sigismondo--initials that are found in every available place throughout the building--and the coat of arms of the Malatesta.
On the north and south sides of the building a grand row of seven broad round arches, on massive rectangular piers, throws a deep shadow on to the sarcophagi of the men who were Sigismondo's companions in his peaceful hours. These sarcophagi are placed between the piers, well above the spectator, on the basement which is built out from the brick wall of the original Gothic cathedral. Like the façade, this grand colonnade and its base are lined with white marble. Among the sarcophagi is one which contains a trophy brought by Sigismondo from the East.
