Some scholars believe that the troubadors may have had Arabian origins, with Magda Bogin stating that the Arab poetic and musical tradition was one of several influences on European "courtly love poetry". Évariste Lévi-Provençal and other scholars stated that three lines of a poem by William IX of Aquitaine were in some form of Arabic, indicating a potential Andalusian origin for his works. The scholars attempted to translate the lines in question and produced various different translations. The medievalist Istvan Frank contended that the lines were not Arabic at all, but instead the result of the rewriting of the original by a later scribe.
