## What you would see

A cream-colored vellum page with a compact block of Latin text in black and red ink, positioned slightly right of center. At the upper left of the text block sits an illuminated initial: a capital C with a deep blue ground, gold outline and infill of red and blue scrollwork dotted with white highlights. Running down the left side of the text is a vertical border decoration nearly the full height of the written area. It consists of stylized acanthus vines in bright blue and golden ochre, intertwined with delicate stems. Around the vines are small blossoms: at the top, five blue five-petaled flowers with gold centers and elongated green leaves; at the bottom, six red flowers with gold centers and similar green foliage. Tiny gold berries and extremely fine black penwork tendrils fill the spaces between. The vellum has a slightly grainy texture, with ochre foxing spots along the top edge and a darker, yellowed stain along the bottom margin. The light is even and flat, as in a reproduction, emphasizing the sheen of the gold and the saturation of the pigments. In the foreground the initial and border bar dominate; in the background the empty parchment and the dense lines of angular Gothic script with abbreviations and consistent, tight lettering.

## How to look at it

Start with the gold and blue initial that opens the passage, then trace the vine scroll down the left margin. Notice how the white dots and fine black filaments create lightness and movement around the dense text.

## Context

This folio is the opening of the Gospel of Matthew from a Book of Hours made for the Use of Rouen, dated about 1470 and executed in ink, tempera and gold on vellum. It is attributed to the Master of the Geneva Latini, the leading illuminator active in Rouen from 1460 to 1480, named after a manuscript now in Geneva. The page begins with Cum natus esset Jesus in Bethlehem. According to the Cleveland Museum of Art, where it is housed, Rouen was a major center of book production in the late 1400s, supported by the wealthy chapter of its cathedral. The original patron of this specific volume is not recorded.

## Curious detail

Books of Hours were private devotional books for laypeople, and the Use of Rouen means its prayers and calendar follow the specific liturgical customs of the diocese of Rouen.

## Questions

- What role does the illuminated border play beyond decorating the sacred text?
- How does seeing the scripture framed by flowers and gold change how you read it compared to plain text?
- What does the pairing of dense script and lush plant ornament suggest about the book as a valued object?
