One of the most famous and evocative episodes in Rimini’s religious history is the so-called the Eucharistic miracle of the mule, traditionally dated to the year 1223 and linked to the presence in the city of Saint Anthony of Padua.
Rimini in the 13th century: an open and complex city
At the beginning of the 13th century, Rimini was a vibrant city, a hotbed of political, cultural and religious activity. Alongside the Catholic Church, there was a sizeable community of Patari, a religious movement founded in Milan in the 11th century, which advocated a Church that was poor, morally pure and free from clerical corruption.
After an initial period of tolerance, Patarism had been declared heretical by the Church; Rimini, however, continued to show itself to be relatively open towards this heterodox movement, which had strong social and artisanal roots there.
Bonvillo’s challenge
The Rimini Patari were led by Bonvillo, a figure who, according to tradition, lived in a house overlooking what is now Piazza Tre Martiri. Right there, a plaque still bears his name today.

St Anthony arrived in Rimini to preach the real presence of Christ in the Eucharist, a dogma strongly contested by the Patarians. At a time when theological debate was often accompanied by ‘visible’ demonstrations, Bonvillo is said to have issued a challenge to the saint: to prove the truth of the Eucharist by means of a miracle.
The Miracle of the Mule
According to the account handed down by hagiographic sources, Bonvillo had a mule locked up in the stable for three days without food. On the appointed day, the animal was led into the square and placed in front of a manger filled with fodder. At the same time St Anthony, after celebrating Mass, he led a procession the consecrated host and presented it to the mule, uttering solemn words of command and reverence.
Tradition has it that The animal, ignoring the fodder, is said to have approached the host and he would have knelt before it, arousing astonishment and emotion amongst those present. Regardless of whether the episode is interpreted literally or symbolically — with some seeing it as an edifying tale and others as an allegory of faith — the event had a profound impact on the collective imagination.
Conversion and urban memory

The presence of the Patari has left a lasting mark on the city’s place names: in Rimini’s historic centre, there is Via Patara, which commemorates the old neighbourhood where they lived and worked, amongst their homes and craft workshops.

Between faith, history and tradition
The miracle of the mule, beyond its miraculous aspect, is a faithful reflection of the Middle Ages: an era in which faith was expressed through tangible signs, preaching was confronted with heresy in the public sphere, and the city became the scene of events destined to become ingrained in the collective memory.
Even today, this episode remains one of the most powerful narratives shaping the identity of medieval Rimini, weaving together spirituality, urban history and folk tradition.
