At first sight this may appear to be a manuscript because it has been embellished with a painted border, miniature, and initials illuminated with gold.
In fact it is a printed book, but only the black letters and one line of text in red has been printed from moveable metal type. All the rest of the decoration has been added by hand. This was not uncommon in the early years of printing, as printers used the traditional methods to add the expected decorative features. 

This page shows two different treatments of initials. Apart from the illuminated ones there is one drawn in penwork, where the printer’s guide letter “r” is clearly visible under the red ink.
The more unusual feature is the miniature of the author, Pope Gregory IX, in the act of writing with his quill.

The style of decoration in this printed book is quite different from the Gregory which was printed in Renaissance Italy. The Speculum historiale was printed in Germany, and has a typical acanthus leaf border developing out of the illuminated initial “Q”.
