Manuscript produced in Italy, either in late 1471 or early 1472, after the election of Sixtus IV to the Papacy. The work is a dedication copy to Pope Sixtus IV of a moral treatise, consisting of three dialogues written by Bartolomeo Sacchi, more commonly known as Bartolomeo Platina. This is the second version of the dialogue, with an earlier version called 'De falso ac vero bono' dedicated to Pope Paul II.

The work starts with a dedication to Sixtus IV by Bartolomeo Platina on folios 1r to 3r. The full text of 'De falso et vero bono' then runs from folios 4r to 87v.

The scribe of the manuscript was originally believed to be Antonio Tophio; however, this was cast into doubt by Alfred Fairbank, and scholars have since confirmed that the hand is that of Bartolomeus Sanvito.

The work is written in a humanistic bookhand. De La Mare has described Sanvito's hand here as round, spacious and firm, and notes that there are pronounced serifs on ascenders and descenders. The abbreviation for 'quam' appears in the new form, and the 'ct' ligature is dented and long, while the one for 'st' is mainly round and regular in size, but occasionally also dented. There are 22 lines of text to a page. It has been suggested that after Sanvito provided the underdrawing for the faceted initials, the illumination was then executed by him or by another minor artist.

The main text is written in dark brown ink. Other decorative elements to the text are provided in blue, red, green, purple and gold.

The headings and incipits contain coloured epigraphic capitals and there is a colophon in small Greek capitals in blue.

Folio 1r has a faceted initial in red which is highlighted in gold and is on a square purple ground. This ground is decorated with leaves and acorns in gold and an oak tree in a chiaroscuro landscape. Below there is a medallion with the arms of Sixtus IV on a ground divided per pale in red, white and green, all within a simple frame shredded in blue and purple.

There are further decorated initials on folios 4r, 33v, 36r, 60r, and 62v. These are in blue, silver, purple or gold, with some highlighted in gold or silver, on rectangular grounds of pale mauve, blue, red or silver. These are also decorated with acorns and oak leaves, some singly and some in sprays.

Throughout the work the names of various interlocutors are present in small half-line epigraphic capitals set within the text, which are in blue for 'Platyna' and in gold for the others. The authorities quoted and the subjects discussed are indicated in the margins also in colour.

Each folio has been blind-ruled recto and verso.

There are alphabetical quire signatures running 'A-[I]' in the lower margins of the verso sides.

Small parts of the main text are in Greek on folios 7v, 8r, 9v, 14v, 67v, and 79v.
