The manuscript, which is of unknown provenance, has the usual title (with the false form `philosomie`) (page 1), preface to Frederick II (page 1), and three books (pages 2, 22, 34). The text is followed (page 49; on three of 8 originally blank pages) by a list of chapters in an 18th-century hand, which was also responsible for the pagination.

At the end of the text (page 48) is the note `est Beltreamini de riuola`. On page 57 is a note, early 15th century, on the geography of Tuscany intended to clarify a war narrative. On folio i are written some Latin verses, 18th century, on folio i verso is a deleted note `M.(?) Laurentius(?) …’, ?16th century, and pasted to the inside front cover is a note of the incipit of this manuscript and of another of the same work which was sold at Sotheby`s in June, 1843, lot 1354.
