Cythara The word cythara was used generically for a wide variety stringed instruments of medieval and Renaissance Europe, including not only the lyre and harp but also necked, string instruments. In fact, unless a medieval document gives an indication that it meant a necked instrument, then it likely was referring to a lyre. It was also spelled "cithara" or "kithara" and was Latin for the Greek lyre. However, lacking names for some stringed instruments from the medieval period, these have been referred to as fiddles and citharas/cytharas, both by medieval people and by modern researchers. The instruments are important as being ancestors to or influential in the development of a wide variety of European instruments, including fiddles, vielles, violas, citoles, guitars. Although not proven to be completely separate from the line of lute-family instruments that dominated Europe (lute, oud, gittern, mandore), arguments have been made that they represent a European-based tradition of instrument building, which was for a time separate from the lute-family instruments.
