Epigonion

An epigonion (ἐπιγόνιον) was an ancient stringed instrument. It had forty strings and was similar to a harp or a psaltery.
An epigonion was named after Epigonus of Ambracia, an inventor of the instrument.
The epigonion is a part of the Lost Sounds Orchestra, alongside such ancient instruments as salpinx, aulos, barbiton and syrinx.
