Слово о полку Игореве
In "The Tale of Igor's Campaign" a similar sounding term is used, recorded being inscribed on coins, deriving from the Turkic for 'captive' or 'slave'. The same term also appears in the Ipatiev Chronicle, meaning 'captive'. A second mention of the term is made in "The Tale of Igor's Campaign" when Igor is captured by the Polovtsi; this event is recorded as a riddle: "And here Prince Igor exchanged his golden saddle of a prince for the saddle of a Koshey (slave)."
