Vegetable Gold

Crocus sativus Reseda luteola

Incomparably the most important yellow in medieval painting is the metal gold. Yellow pigments, however, played a significant part in the pageant of medieval technique. One of the most important services required of them was to imitate the appearance of gold. Another of their chief functions was to modify the qualities of greens, and to a less extent, of reds. Of all their uses, perhaps the least important was to represent yellow things.

—Daniel Thompson, The Materials and Techniques of Medieval Painting

The vegetable yellows used in medieval illumination were more readily prepared and much safer to use than mineral yellows like realgar or orpiment. Above, left: The brilliant red-orange stigmas of the autumn-blooming saffron crocus, used by medieval cooks as a colorant and a seasoning, were also exploited by illuminators. Right: Flower spikes of weld, the most ancient yellow dyestuff known. When processed as a pigment, this weedy biennial provided manuscript painters with a bright vegetable yellow.

A number of plants were exploited for coloring matter in the Middle Ages, whether to tint foodstuffs or to furnish dyes and pigments. By no means all, or even many, artist’s pigments were of vegetable origin; mineral colors were used for wall painting, where the more delicate and fugitive nature of vegetable colors was inappropriate. In book painting, a combination of vegetable and mineral colors was employed. The same plant that yielded a dye for textiles could be prepared as a pigment and used by illuminators. Several species produced a viable yellow, including weld, saffron, and celandine; as Daniel Thompson observes, these vegetable yellows served both to imitate the appearance of gold, and to modify greens and reds.

Lesser Celandine

Colony of Lesser Celandine

A colony of lesser celandine (Ranunculus ficaria) growing in the orchard below the south wall of Bonnefont garden.

The shining yellow flowers of lesser celandine star the grounds below Bonnefont garden in March and April, but the blossoms and the heart-shaped leaves of this spring ephemeral will disappear altogether by summer. The tuberous roots, which lie just beneath the surface of the soil, will remain dormant until the following spring. This invasive medieval species is not grown within the walls of The Cloisters, but has long been at home throughout the northeastern United States. (See the Ranunculus ficaria page of the Invasive Plant Atlas of New England website.)

Swallow Wort

Greater Celandine Broken Stem of Greater Celandine (detail)

Greater celandine, or swallow wort, has an ancient association with the common European swallow; it was believed that mother birds dropped the juice of the celandine into the eyes of their blind fledglings. The plant and the bird were linked for many centuries, and celandine’s reputation as a sovereign remedy for clearing eyes and sharpening the sight outlasted the Middle Ages.  Photographs by Corey Eilhardt

It seems to be called Chelidonia because it springs out of the ground together with ye swallows appearing, & doth wither with them departing. Somme have related that if any of the swallowes’ young ones be blinde, the dames bringing this herbe, doe heale the blindness of it.

—Dioscorides, De Materia Medica, Book II: 211

The greater celandine, Chelidonium majus is native to Europe and western Asia, but is widely naturalized in waste places in the eastern United States, where it is commonly known as “swallow wort.” For more information, see the U.S.D.A. Plants Database. (Chelidonium majus is characterized as greater celandine, to distinguish it from an altogether different species, Ranunculus ficaria, widely known as lesser celandine.) Read more »
