Count Gennaro Arcucci (died 1800) was an Italian physician, antiquarian and a hero of the island of Capri and Caprese martyr in the Bourbon Restoration of Ferdinand I. He was said to have been the principal signori of the island [1] who used to "entertain the King during his visits to the island and offer him draughts of his far-famed 'Tears of Tiberius'". [2] He was hanged by the Bourbons in 1800, "as a 'liberal'". [1] A plaque commemorates him on the Piazza Umberto I.
