|Poem of the Cid Page Folio 40V|
It is clear that the manuscript was a written record of a song recited by roving minstrels. More recently scholars have believed the old-fashioned speech to be an example of using this kind of language for epic poetry. Alternatively, it may reflect the date of the oral origination of the song. In any case, they accept Per Abbat's claim to have written down the original in 1207. The dating of the handwriting is attributed to the existing manuscript having been made in the 14th Century from an earlier original.
Based on linguistic grounds, familiarity with the local geography, and glowing references to the citizens of certain towns, scholars have argued that the minstrel poet was from Medinaceli, or Esteban de Gormaz; or Fresno de Caracena, all close together in the south of present-day Soria province. Others speculate the author was a monk at the monastery of San Pedro de Cardena near Burgos. They point out the manuscript was found at Vivar, and that the monks were interested in promoting the pilgrim traffic to the Cid's grave there and were familiar with French epic poems.
