a stringed instrument of music among the ancient Hebrews, having three or four chords to it, although there is reason to question the antiquity of this instrument; both because it requires a hair bow, which was a kind of plectrum not known to the ancients, and because it so much resembles the modern viol. Kircher took the figures of this, the machul, chinnor, and psaltery, from an old book in the Vatican library.
