The kilim, also spelled klim or kelim, is a rug woven instead of knotted. Its name of Indo-European origin also gave rise to the Persian guilim or gelim and the Greek kalymma which denotes the Calymmian era. Kilims are found mainly in the Middle East, notably in Iran (particularly in certain provinces: Kurdistan, Kerman, Lorestan, Fars, Sistan and Baluchistan and Golestan), in Turkey, in the Caucasus as well as in Central Asia and emerged almost 10,000 years ago as evidenced by numerous remains. The warp of the kilim is often made of cotton, wool, silk or goat hair while the weft is made of wool, silk or goat hair.
