Epigonion

An epigonion was an ancient stringed instrument mentioned in Athenaeus (183 AD), probably a psaltery. The epigonion was invented, or at least introduced into Greece, by Epigonus of Ambracia, a Greek musician of Ambracia in Epirus, who was admitted to citizenship at Sicyon as a recognition of his great musical ability and of his having been the first to pluck the strings with his fingers, instead of using the plectrum. The instrument, which Epigonus named after himself, had forty strings.
