CIRILLO, DOMENICO Italian physician, botanist, and revolutionist, was appointed as a young man to a botanical professorship, and later travelled to France and England, where he was elected a fellow of the Royal Society. On his return to Naples he was appointed successively to the chairs of practical and theoretical medicine. He wrote voluminously on scientific subjects, although only his philosophical treatise Virtu morali dell' Asine is now remembered, and acquired a large med ical practice. On the establishment of the Parthenopean republic in Naples, Cirillo became president of the legislative commission. When the town surrendered to Cardinal Ruffo, the vengeance of the royalists was wreaked upon Cirillo among many others. De spite Lady Hamilton's intercession on his behalf, Nelson had him hanged on Oct. See L. Conforti, Napoli nel 1799 (Naples, 1889) ; C. Giglioli, Naples in 1799 (1903) ; C.
