## What you would see

A vellum folio in pale ivory with a softly mottled, slightly cockled surface and faint age staining along the outer edges. The left side holds a dense column of Gothic textualis script in deep black ink, remarkably even, with thin horizontal ruling still visible. Rubrics in vivid vermilion interrupt the black text, marking new prayers, and a small initial in bright blue with white filigree and a burnished gold ground anchors the lower third. Running the full height of the right margin is an elaborate border illumination. Interlaced acanthus scrolls in ultramarine blue and burnished gold twist upward in elegant S-curves, dotted with tiny gold bezants on a finely stippled black ground. Nestled among the scrolls are small five-petaled flowers in blue, pale yellow and peach-pink, with sage and olive green leaves delicately shaded. The gold catches light with a metallic sheen, contrasting with the matte tempera of the petals. The foreground is dominated by crisp letterforms; the background is generous blank vellum above and below, emphasizing the intimate, handheld scale of a private prayer book meant for close, slow viewing.

## How to look at it

Start with the dark, rhythmic column of text and use the red rubrics as resting points. Then follow the vertical blue and gold scrollwork upward along the right margin. Linger on the tiny tricolor pansy-like blossoms and the black dotted ground that makes the gold shimmer.

## Context

This folio comes from a Book of Hours made for the Use of Rouen, dated about 1470 and attributed to the Master of the Geneva Latini, active in Rouen from 1460 to 1480. According to Cleveland Museum of Art records, the artist is named after a manuscript now in Geneva and was Rouen’s leading illuminator in the second half of the 15th century. At that time Rouen was an established center of book production, supported by the wealthy cathedral chapter that commissioned books and maintained an extensive library. The medium is ink, tempera and gold on vellum. Folio 133r contains devotional texts and responses, with the characteristic marginal decoration of the Rouen workshop.

## Curious detail

Books of Hours were personal prayer books for laypeople, and the phrase Use of Rouen means the volume follows the specific liturgical customs of the Diocese of Rouen, a key clue for localizing its production.

## Questions

- How does the contrast between the strict Gothic script and the flowing plant scroll affect the mood of the page?
- What might the lavish use of blue and burnished gold suggest about the owner and the way this book was handled?
