This was a fortunate move, because the Real Fortress was destroyed by a fire in 1862, along with its library and all things therein.
In 1922, the manuscript was found by Higinio Anglés in the Chapterhouse Archives of the Segovia Cathedral.
Unlike other cancioneros of the period, it does not have a table of contents, neither are the works grouped by musical genre (romance, motet, etc.)
The cancionero is divided into two parts: The codex comprises 204 works in total, in five different languages (74 in Latin, 50 in French, 38 in Spanish, 34 in Flemish/Dutch and 8 in Italian).
Among the genres found in it, there are masses, motets, villancicos, chansons and instrumental pieces.
