## What you would see

The image presents a single vellum page in pale cream with a smooth, slightly luminous surface, photographed straight on with a wide blank margin at the bottom. The text block fills the upper half, written in dense black ink in Gothic textualis with even lines and a few highlighted initials. On the left edge of the text stands a tall vertical decorated initial spanning the full height of the paragraph: its structure is formed by interlaced foliage in deep ultramarine blue and burnished gold that catches the light, with curling acanthus-like scrolls moving upward. From its top and base sprout slender stems bearing elongated green leaves and small five-petaled flowers in wine red and blue with golden centers and green buds, painted in opaque tempera with precise, fine outlines. The illumination is soft and even, without harsh shadows, emphasizing the contrast between the light parchment, the dark density of the script, and the metallic sheen of the gold. One can sense the soft fibrous quality of the vellum, the slight relief of the ink, and the meticulous detailing of the vegetal motifs at an intimate scale meant to be held in the hands, typical of a private devotional book.

## How to look at it

Start with the vertical band of blue and gold on the left and follow its scrolling vines from bottom to top. Then pause on the small red and green blossoms sprouting from the foliage and notice how they soften the strict grid of the text. Finally compare the metallic gleam of the gold with the matte black ink and the warm glow of the parchment.

## Context

This leaf is from a Book of Hours for the Use of Rouen, dated about 1470 and attributed to the Master of the Geneva Latini, active in Rouen from 1460 to 1480. It is executed in ink, tempera and gold on vellum and belongs to a bound volume. According to Cleveland Museum of Art records, Rouen was an important center of book production in the late 1400s, supported by the wealthy chapter of its cathedral, which commissioned books and maintained an extensive library. Stationers and booksellers were probably concentrated near the cathedral precinct. This artist, named after a manuscript now in Geneva, was Rouen’s leading illuminator in the second half of the 1400s. No further specific details about this folio are recorded.

## Curious detail

Books of Hours were among the most common private prayer books for well-to-do laypeople in the later Middle Ages and were often illuminated with real gold leaf on vellum, as seen shining in this initial.
