A musical instrument mentioned exclusively in Daniel's account of Nebuchadnezzar's orchestral ensemble. This is a Greek loanword (psalterion) that entered Aramaic during the exilic period, designating a triangular stringed instrument similar to a harp or lyre. Daniel 3 repeats the instrument four times as part of the royal orchestra's lineup that signals when subjects must bow before the golden image. The word's Greek origin reflects the cultural interchange of the Babylonian exile.
