The instruments referred to in the West as "spike fiddles" are referred to in the native language of the originating culture as some variation of "kamanche." Kamanche is spelled a variety of ways based on the regional language—a region that includes the Middle East, Persia, and the Balkans (includes Turkey, as the name implies; note particularly the cultural group of the Kurds, which crosses several country borders). Check out The Garland Encyclopedia of World Music to learn more, particularly the "Middle East" volume--look up "kamanche" and its variants in the index. Grove Music Online also has some interesting (and more summarized) information.
