The gittern was a relatively small gut strung round-backed instrument that first appears in literature and pictorial representation during the 13th century in Western Europe (Iberian Peninsula, Italy, France, England). It is usually depicted played with a quill plectrum. It was also called the guitarra in Spain, guiterne or guiterre in France, the chitarra in Italy and quintern in Germany. A popular instrument with court musicians, minstrels, and amateurs, the gittern is considered ancestral to the modern guitar; possibly other instruments like the mandore and gallichon.
From the early 16th century, a vihuela shaped (flat-backed) guitarra began to appear in Spain - then France, existing alongside the gittern. Although the round-backed instrument appears to have lost ground to the new form which gradually developed into the guitar familiar today, the influence of the earlier style continued. Examples of lutes converted into guitars exist in several museums, while purpose built instruments like the gallichon utilised the tuning and single string configuration of the modern guitar. A tradition of building round-backed guitars in Germany continued to the 20th century with names like gittar-laute and Wandervogellaute.
