The Etruscans had considerable proficiency in philosophy and medicine, and to this people, as well as to the Sabines, the Ancient Romans were indebted for knowledge. Numa Pompilius, of Sabine origin, who was King of Rome 715 B.C., studied physical science, and, as Livy relates, was struck by lightning and killed as the result of his experiments, and it has therefore been inferred that these experiments related to the investigation of electricity. It is surprising to find in the Twelve Tables of Numa references to dental operations. In early times, it is certain that the Romans were more prone to learn the superstitions of other peoples than to acquire much useful knowledge. They were cosmopolitan in medical art as in religion. They had acquaintance with the domestic medicine known to all savages, a little rude surgery, and prescriptions from the Sibylline books, and had much recourse to magic. It was to Greece that the Romans first owed their knowledge of healing, and of art and science generally, but at no time did the Romans equal the Greeks in mental culture. Pliny states that "the Roman people for more than six hundred years were not, indeed, without medicine, but they were without physicians." They used traditional family recipes, and had numerous gods and goddesses of disease and healing. Febris was the god of fever, Mephitis the god of stench; Fessonia aided the weary, and "Sweet Cloacina" presided over the drains. The plague-stricken appealed to the goddess Angeronia, women to Fluonia and Uterina. Ossipaga took care of the bones of children, and Carna was the deity presiding over the abdominal organs. Temples were erected in Rome in 467 B.C. in honour of Apollo, the reputed father of Æsculapius, and in 460 B.C. in honour of Æsculapius of Epidaurus. Ten years later a pestilence raged in the city, and a temple was built in honour of the Goddess Salus. By order of the Sibylline books, in 399 B.C., the first _lectisternium_ was held in Rome to combat a pestilence. This was a festival of Greek origin. It was a time of prayer and sacrifice; the images of the gods were laid upon a couch, and a meal was spread on a table before them. These festivals were repeated as occasion demanded, and the device of driving a nail into the temple of Jupiter to ward off "the pestilence that walketh in darkness," and "destruction that wasteth at noonday" was begun 360 B.C. As evidence of the want of proper surgical knowledge, the fact is recorded by Livy that after the Battle of Sutrium (309 B.C.) more soldiers died of wounds than were killed in action. The worship of Æsculapius was begun by the Romans 291 B.C., and the Egyptian Isis and Serapis were also invoked for their healing powers.
