Late in the summer of 1374 news of the death of Francesco Petrarca swept through Italy and soon crossed the Alps into the rest of Christendom: during the night of the 18th of July the humanist had died surrounded by his books in his study at Arquà, a village in the Euganean Hills to the south of Padua. Six days later he was buried in pomp in the parish church of that village; it was a funeral attended by a throng that included the signore of Padua, Francesco il Vecchio da Carrara, and the bishops of Padua, of Vicenza, of Verona, and of Treviso. The funeral oration was pronounced by one of the poet's closest Paduan friends, the Augustinian friar Bonaventura Badoer; in a stately ceremony the coffin, borne by sixteen doctors of law, was deposited in the Chiesa Arcipretale.
We performed a new series of measurements on samples that were part of early measurements on radiocarbon (14C) dating made in 1948–1949. Our results show generally good agreement to the data published in 1949–1951, despite vast changes in technology, with only two exceptions where there was a discrepancy in the original studies. Our new measurements give calibrated ages that overlap with the known ages. We dated several samples at four different laboratories, and so we were also able to make a small intercomparison at the same time. In addition, new measurements on samples from other Egyptian materials used by Libby and co-workers were made at UC Irvine. Samples of tree rings used in the original studies (from Broken Flute Cave and Centennial Stump) were obtained from the University of Arizona Laboratory of Tree-Ring Research archive and remeasured. New data were compared to the original studies and other records.
