Gothic

The leaf is overall in good quality. Tears made by Ege from when it was removed are visible, and the parchment is clearly not new. The colors on each side may have leached through to be fairly visible through the vellum, and it seems as if there might be some kind of scribble or doodle near the bottom right columns of text in the recto. Finally, there are a few grey-black dots on the page which I'm not sure about the cause of. 

Blue, red, and gold flower buds on the left side of the text. A few colored bars of these same colors, and there are a few stylized gold leaf letters on each side of the page.

Made in Northwest France, possibly for the Use of Arras (the first three responsories for the Office of the Dead are often found in Books of Hours from Arras).

Written in NW France (likely for the Use of Arras or Paris) in the early 15th century. Possibly identical with the Book of Hours sold at Sotheby's London on 20 December 1948, lot 415. "The Property of a Gentleman." Dismembered by Otto or Louise Ege in the late 1940s, leaves used as no. 45 in Ege's "Fifty Original Leaves from Medieval Manuscripts" portfolios, of which 40 were produced and 31 are known.
