The Arabic rabāb, also known as the spiked fiddle, is the earliest known bowed string instrument and the ancestor of all European bowed instruments, including the rebec, the Byzantine lyra, and the violin. The Arabic oud in Arab music shares an ancestor with the European lute. The oud is also cited as a precursor to the modern guitar. The guitar has roots in the four-string oud, brought to Iberia by the Moors in the 8th century. A direct ancestor of the modern guitar is the "" (Moorish guitar), which was in use in Spain by the 12th century. By the 14th century, it was simply referred to as a guitar.
