Bartolomeo Gradenigo, born in the year 1263 in Venice, emerged from an ancient noble lineage and became a prominent figure in the political landscape of his time. His early career was marked by significant roles, including serving as podestà of Ragusa and Capodistria, and later as procuratore in Venice. Gradenigo was known for his opulent lifestyle, which reflected his wealth as a successful tradesman.
His tenure as the fifty-third Doge of Venice began on 7 November 1339 and lasted until his death on 28 December 1342. Despite the brevity of his reign, it was characterized by relative peace, with notable exceptions such as a revolt in Crete and incursions by Turkish forces. Gradenigo also engaged in diplomatic efforts with Genoa, showcasing his commitment to maintaining Venice's influence.
One of the most remarkable events during his rule occurred on 15 February 1340, when a fierce tempest threatened the city. According to legend, the storm was calmed through the miraculous intervention of St. Mark, St. George, and St. Nicholas, who were brought to the lagoon by a humble fisherman. In gratitude, the saints bestowed upon the fisherman a ring, known as the 'Ring of the Fisherman,' which has since become a cherished part of the ducal jewelry.
Bartolomeo Gradenigo's legacy is immortalized in art, notably in the painting 'The Presentation of the Ring' by Paris Bordone, which depicts the moment the fisherman presents the ring to him. Gradenigo's life was also marked by personal milestones, including three marriages and six children, one of whom was Giustina Capello.
