El manuscrito VTR/4/6 de la BNE, ¿finales del siglo XIII?

The manuscripts of Alfonso X’s works continue to offer questions on which no answer has been given or are open to debate. This happens with the Fourth Part of the BNE VTR/4/6 manuscript, about which the date of this copy is debated and which we will try to show that it was made at the end of the 13th century. For this, we will compare it not only with this same manuscript, which also includes the First Part, but with others such as the version of the Book of Laws, which is the British Library in London, and the copies of the First and the Fourth Parts of the MSS/12793 manuscript, which is in the National Library of Spain. For this comparison, we have selected typical elements of this period and we carried out a statistical analysis, which will determine if this version was copied or not in this period.
