The Medieval Garden Enclosed

Downy thorn apple (Datura metel) growing in a bed in Bonnefont garden devoted to plants used in medieval magic. The common name “thorn apple,” shared with other members of the genus, is derived from the character of the spiny seed capsule. Above: D. metel in bud (left) and bloom (right). This handsome, heat-loving plant flowers profusely from late July until October. Below: Semi-ripe capsule of the downy thorn apple, broken open to show the developing seeds.

The beautiful but sinister thorn apple (Datura metel) is a powerfully hallucinogenic plant employed in medieval magic as well as medicine.

Sesame, also known as “benne,” is a tender, large-leaved, Asian annual grown here in Bonnefont garden. Sesame has been cultivated for some five thousand years and was known to many cultures in antiquity. Although the plant is somewhat rangy and coarse in habit, the tubular flower (above, left) is attractive. The immature green pods (above, right), which will split and spill out their seeds when ripe, contain one of the world’s oldest domesticated oilseeds. The seeds also have a long history of use as a seasoning.??Photographs by Carly Still.

A cultivated plant of fabulous antiquity, sesame (Sesamum indicum) is known as simsim in Arabic, susam in Turkish, sesam in German, s??same in French, sesamo in Italian, and sesame in Spanish. Called sesemt by the ancient Egyptians, it was also grown in Ethiopia in very early times. Sesame seeds were taken from West Africa to America by slave traders; the name “benne” derives from the West African benni. Sesame had long been grown in India and Persia, and was introduced to China by the end of the fifth century A.D. Read more »

Both edible and medicinal plants were classified by their qualities in the Middle Ages. A given plant might be heating, cooling, moistening, or drying in its action on human bodies; the intensity of this action was expressed in degrees. An herb or foodstuff that was a little cooling was “cold in the first degree,” while a very cooling plant was classed as “cold in the fourth degree.” Above, left: Strawberry (Fragaria vesca) was a mildly cooling fruit, being cold and moist in the first degree. Pear (Pyrus communis) was more refreshing, being cold in the second degree and moist in the first.

The medicinal model inherited by the Middle Ages, based largely on humoral theory, was essentially a “cure by contraries” rooted in the idea that illness was the result of an imbalance of the humors???blood, choler, bile, and phlegm???within an individual. Plants and other substances were either warming, cooling, moistening, or drying in their action on human bodies, which were sanguine, phlegmatic, melancholic, or choleric in complexion. Read more »

The Unicorn in Captivity, 1495???1505. The Metropolitan Museum of Art, New York, Gift of John D. Rockefeller Jr., 1937 (37.80.6). The profusion of flowering plants that springs from the millefleurs meadow on which the unicorn rests includes both garden plants and wildflowers. An iris and a clove pink are prominently placed outside the unicorn’s enclosure; both were intensively cultivated in the Middle Ages, but the purple orchis silhouetted against the unicorn’s body depends on a special relationship with microorganisms in its native soil and would not have grown in gardens.

Roses, lilies, iris, violet, fennel, sage, rosemary, and many other aromatic herbs and flowers were prized for their beauty and fragrance, as well as their culinary and medicinal value, and were as much at home in the medieval pleasure garden as in the kitchen or physic garden. These plants were carefully cultivated, but many useful plants of the Middle Ages were found outside the garden walls, or admitted on sufferance.

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.)

The mandrake, credited with both medicinal and magical powers over the course of many centuries, has accumulated more lore than any other plant in the Western tradition. Above: One of a colony of five spring-blooming mandrakes in Bonnefont garden. In March, this famous member of the nightshade family produces tight clusters of short-stemmed bell-shaped flowers.

Mandrake (mandragora) is hot and a little bit watery. It grew from the same earth which formed Adam, and resembles the human a bit. Because of its similarity to the human, the influence of the devil appears in it and stays with it, more than with other plants. Thus a person’s good or bad desires are accomplished by means of it, just as happened formerly with idols he made. When mandrake is dug from the earth, it should be placed in a spring immediately, for a day and a night, so that every evil and contrary humor is expelled from it, and it has no more power for magic or phantasms.

Libanotis which the Romans call Rosmarinus & they which plait crowns use it: the shoots are slender, about which are leaves, small, thick, and somewhat long, thin, on the inside white, but on the outside green, of a strong scent. It hath a warming facultie . . .

???Dioscorides, De Materia Medica, Book III: 89

It is an holy tree and with folk that hath been rightful and just gladly it groweth and thriveth. In growing it passeth not commonly in height the height of our Lord Jesu Christ while he walked as a man on earth, that is man’s height and half, as man is now; nor, after it is 33 years old, it growth not in height but waxeth in breadth and that but little. It never seareth all but if some of the aforesaid four weathers make it.

The trees went to anoint a king over them: and they said to the olive tree: Reign thou over us
And it answered: Can I leave my fatness, which both gods and men make use of, to come to be promoted among the trees?

???Judges 9: 8-9, Douay-Rheims Bible

Olive oil provided fuel for sanctuary lamps throughout the Mediterranean world in antiquity and the Middle Ages, as well as holy oils for religious purposes. Above, left: A menorah flanked by two olive trees, as depicted in the Cervera Bible, recently on view at the Main Building. The brimming vessels?? used to fill the lamp appear at the top of the menorah. Right: A fifth-century standing lamp decorated with a cross; bronze lamps of this type were common in the early Byzantine world.

The olive was held to be the first of trees in both classical and biblical antiquity, prized above even the grapevine and the fig. A gift of the goddess Athena, the sacred olive symbolized the arts of peace and prosperity; the ruthless destruction of an enemy’s olive groves in wartime was held to be sacrilegious act. The Roman natural historian Pliny, writing in the first century A.D., attests that Athena’s olive was still venerated on the Athenian acropolis in his day (Historia naturalis, XVI 239???40). Although slow to bear, the tree is very long lived, surviving for hundreds of years. (The SpiceLines blog features an illustrated post about a Spanish olive estimated to be eighteen hundred years old.)

The evergreen bay laurel (Laurus nobilis), a symbol of victory and eternal life, is not as tender as some other Mediterranean species, but it must be grown in pots and wintered over indoors at The Cloisters. Above, left: Bay laurel topiaries like this one spend the winter in the glassed-in arcades of Cuxa cloister and return to Bonnefont herb garden in May. Right: The magnificent bay tree that flourishes at the center of Girolamo dai Libri’s Madonna and Child with Saints represents Resurrection, and is juxtaposed with the naked limbs of a dead tree.

The laurel itself is a bringer of peace, inasmuch as to hold a branch of it out even between enemy armies is a token of cessation of hostilities. With the Romans especially it is used as a harbinger of rejoicing and of victory, accompanying despatches and decorating the spears and javelins of the soldiery and adorning the generals??? rods of office. From this tree a branch is deposited in the lap of Jupiter the All-good and All-great whenever a fresh victory has brought rejoicing, and this is not because the laurel is continually green, nor yet because it is an emblem of peace, as the olive is to be preferred in both respects, but because it flourishes in the greatest beauty on Mount Parnassus, and consequently is thought to be also dear to Apollo, to whose shrine even the kings of Rome at that early date were in the custom of sending gifts and asking for oracles in return.

Potted plants too tender to spend the winter in Bonnefont garden are trucked inside and brought up to Cuxa cloister, which is??glazed in mid-October. Mediterranean plants such as bitter orange, myrtle, and bay laurel spend the cold season in the sunny arcades and??are brought back out to the herb garden when the glass comes down in mid-April.

While the medieval plant collection at The Cloisters includes a good number of northern European species, a great many of the plants grown in the Bonnefont Cloister herb garden are Mediterranean in origin. Not all of these southern European plants are hardy for us here in New York City. The garden is a sheltered U.S.D.A. Hardiness Zone 7, and the fig tree (Ficus carica), poet’s jasmine (Jasminum officinale), and lavender (Lavandula angustifolia) do just fine outdoors, but more tender species like bitter orange (Citrus aurantium), rosemary (Rosmarinus officinalis), bay laurel (Laurus nobilis), and dittany of Crete (Origanum dictamnus) must be brought inside and protected from the cold.
