This paper will offer a new critical edition, with a new examination of the manuscript tradition, of Granet’s Comte Karle, ye·us vuelh far entenden (BdT 189,1), a political sirventes composed in 1257 and dedicated to Charles of Anjou. The main problem is due to the anomaly represented by the forth stanza, which has two lines more and a different rhyme scheme. In 1929, Amos Parducci proposed to consider this stanza like an interpolation, but it’s more likely that the fourth stanza is the fusion of three incomplete stanzas made in the archetype of two manuscripts that preserve the text.
