Hortus conclusus is a Latin term, meaning literally "enclosed garden". Both words in hortus conclusus refer linguistically to enclosure.Clifford, A History of Garden design, (New York:Praeger) 1963:17. It describes a type of garden that was enclosed as a practical concern, a major theme in the history of gardening, as walled gardens used to be more commonplace.Rob Aben and Saskia de Wit, The Enclosed Garden: History and Development of the Hortus Conclusus and its Re-Introduction into the Present-Day Urban Landscape (Rotterdam) 1999. A typological catalogue of design features and a design manual. The garden room is a similar feature, usually less fully enclosed.

Having roots in the Song of Songs in the Hebrew scriptures, the term hortus conclusus has importantly been applied as an emblematic attribute and a title of the Virgin Mary in Medieval and Renaissance poetryStanley Stewart, The Enclosed Garden: The Tradition and Image in Seventeenth-Century Poetry (Madison: University of Wisconsin Press) 1966, discussed late sixteenth and seventeenth-century poetry in English; its four first chapters trace the hortus conclusus theme in European literatures and the visual arts. and art, first appearing in paintings and manuscript illuminations about 1330.Michelle P. Brown, "The World of the Luttrell Psalter" British Library 2006,Brian E. Daley, "The 'Closed Garden'and the 'Sealed Fountain': Song of Songs 4:12 in the Late Medieval Iconography of Mary", Elizabeth B. Macdougall, editor, Medieval Gardens, Dumbarton Oaks Colloquium 9) 1986, traced the sudden development about 1400 of painted images of the Virgin Mary in a hortus conclusus.

The Virgin Mary as hortus conclusus

The term hortus conclusus is derived from the Vulgate Bible's Canticle of Canticles (also called the Song of Songs or Song of Solomon) 4:12, in Latin: "Hortus conclusus soror mea, sponsa, hortus conclusus, fons signatus" ("A garden enclosed is my sister, my spouse; a garden enclosed, a fountain sealed up.")The whole text This provided the shared linguistic culture of Christendom, expressed in homilies expounding the Song of Songs as allegory where the image of King Solomon's nuptial song to his bride was reinterpreted as the love and union between Christ and the Church, the mystical marriage with the Church as the Bride of Christ.

The verse "Thou art all fair, my love; there is no spot in thee" (4.7) from the Song was also regarded as a scriptural confirmation of the developing and still controversial doctrine of Mary's Immaculate Conception – being born without Original Sin ("macula" is Latin for spot).

Christian tradition states that Jesus Christ was conceived to Mary miraculously and without disrupting her virginity by the Holy Spirit, the third person of the Holy Trinity. As such, Mary in late medieval and Renaissance art, illustrating the long-held doctrine of the perpetual virginity of Mary, as well as the Immaculate Conception, was shown in or near a walled garden or yard. This was a representation of her "closed off" womb, which was to remain untouched, and also of her being protected, as by a wall, from sin. In the Grimani Breviary, scrolling labels identify the emblematic objects betokening the Immaculate Conception: the enclosed garden (hortus conclusus), the tall cedar (cedrus exalta), the well of living waters (puteus aquarum viventium), the olive tree (oliva speciosa), the fountain in the garden (fons hortorum), the rosebush (plantatio rosae).Timothy Husband, reporting the exhibition and its catalogue in The Burlington Magazine, 125, No. 967 (October 1983:643). Not all actual medieval horti conclusi even strove to include all these details, the olive tree in particular being insufficiently hardy for northern European gardens.

The enclosed garden is recognizable in Fra Angelico's Annunciation (illustration at above left), dating from 1430-32.

Two pilgrimage sites are dedicated to Mary of the Enclosed Garden in the Dutch-Flemish cultural area. One is the statue at the hermitage-chapel in Warfhuizen: "Our Lady of the Enclosed Garden". The second, Onze Lieve Vrouw van Tuine (literally "Our Lady of the Garden"), is venerated at the cathedral of Ypres.

Actual gardens All gardens are by definition enclosed or bounded spaces, but the enclosure may be somewhat open and consist only of columns, low hedges or fences. An actual walled garden, literally surrounded by a wall, is a subset of gardens. The meaning of hortus conclusus suggests a more private style of garden.

In the history of gardens the High Medieval hortus conclusus typically had a well or fountain at the center, bearing its usual symbolic freight (see "Fountain of Life") in addition to its practical uses. The convention of four paths that divided the square enclosure into quadrants was so strong that the pattern was employed even where the paths led nowhere. All medieval gardens were enclosed, protecting the private precinct from public intrusion, whether by folk or by stray animals. The enclosure might be as simple as woven wattle fencing or of stout or decorative masonry; or it might be enclosed by trelliswork tunneled pathways in a secular garden or by an arcaded cloister, for communication or meditative pacing.

The origin of the cloister is in the Roman colonnaded peristyle, as garden histories note. The ruined and overgrown Roman villas that were so often remade as the site of Benedictine monasteries had lost their planted garden features with the first decades of abandonment: "gardening, more than architecture, more than painting, more than music, and far more than literature, is an ephemeral art; its masterpieces disappear, leaving little trace."Clifford 1963, eo. loc.. Georgina Masson observed: "When, in 1070, the abbey of Cassino was rebuilt,The site was that of a Roman imperial villa, as was the site of Benedict's monastery at Subiaco, occupying Nero's former villa. the garden was described as 'a paradise in the Roman fashion'." But it may have been merely "the aura of the great classical tradition" alone that had survived.Masson, Italian Gardens (New York: Abrams) 1961:46. The ninth-century idealised plan of Saint Gall (illustration) shows an arcaded cloister with a central well and cross-paths from the centers of each range of arcading. But when a consciously patterned garden was revived for the medieval cloister, the patterning came through Norman Sicily and its hybrid culture that adapted many Islamic elements, in this case the enclosed North African courtyard gardens, ultimately based on the Persian garden tradition.

The practical enclosed garden was laid out in the treatise by Pietro Crescenzi of Bologna, Liber ruralium commodorum, a work that was often copied, as the many surviving manuscripts of its text attest, and often printed in the fifteenth and sixteenth centuries. Late medieval paintings and illuminations in manuscripts such as for The Romance of the Rose – where the garden in the text is largely allegorical – often show a turfed bank for a seat as a feature of the hortus conclusus. Only in the fifteenth century, at first in Italy, did some European gardens begin to look outward.

Sitting, walking and playing music were the activities most often portrayed in the numerous fifteenth-century paintings and illuminated manuscripts, where strenuous activities were inappropriate. In Rome, a late fifteenth-century cloister at San Giovanni dei Genovesi was constructed for the use of the Genoese natio, an Ospitium Genoensium, as a plaque still proclaims, which provided shelter in cubicles off its vaulted encircling arcades, and a meeting place and shelter reuniting those from the distant home city.Wolfgang Lotz, "Bramante and the Quattrocento Cloister" Gesta 12.1/2 (1973):111-121) p. 113.

Somewhat earlier, Pietro Barbo, who became Pope Paul II in 1464, began the construction of a hortus conclusus, the Palazzetto del Giardino di San Marco, attached to the Venetian Cardinals' Roman seat, the Palazzo Venezia.It was dismantled and re-erected in 1910 to make space for Piazza Venezia. It served as Paul's private garden during his papacy; inscriptions stress its secular functions as sublimes moenibus hortos...ut relevare animum, durasque repellere curas, a garden of sublime delights, a retreat from cares, and praise it in classicising terms as the home of the dryads, suggesting that there was a central grove of trees, and mentioning its snowy-white stuccoed porticoes. An eighteenth-century engraving shows a tree-covered central mount, which has been recreated in the modern replanting, with box-bordered cross and saltire gravelled paths.Hinc hortos dryadumque domos et amena vireta/ Porticibus circum et niveis lustrata columnisLotz 1973 eo. loc. and figs 10 and 11.

The Farnese Gardens (Orti Farnesiani sul Palatino – or "Gardens of Farnese upon the Palatine") were created by Vignola in 1550 on Rome's northern Palatine Hill, for Cardinal Alessandro Farnese (1520–89). These become the first private botanical gardens in Europe (the first botanical gardens of any kind in Europe being started by Italian universities in the mid-16th century, only a short time before). Alessandro called his summer home at the site Horti Farnesiani, probably in reference to the hortus conclusus. These gardens were also designed in the Roman peristylium style with a central fountain.

In art

The hortus conclusus was one of a number of depictions of the Virgin in the late Middle Ages developed to be more informal and intimate than the traditional hieratic enthroned Virgin adopted from Byzantine icons, or the Coronation of the Virgin. The subject began as a specific metaphor for the Annunciation,Schiller, pp 52-55 but tended to develop into a relaxed sacra conversatione, with several figures beside the Virgin seated, and less specific associations. Germany and the Netherlands in the 15th century saw the peak popularity of this depiction of the Virgin, usually with Child, and very often a crowd of angels, saints and donors, in the garden; the garden by itself, to represent the Virgin, was much rarer. Often walls or trellises close off the sides and rear, or it may be shown as open, except for raised banks, to a landscape beyond. Sometimes, as with a Gerard David's The Virgin and Child with Saints and Donor (below) the garden is very fully depicted; at other times, as in engravings by Martin Schongauer, only a wattle fence and a few sprigs of grass serve to identify the theme. Italian painters typically also keep plants to a minimum, and do not have grass benches. A sub-variety of the theme was the German "Madonna of the Roses", sometimes attempted in sculptured altarpieces. The image was rare in Orthodox icons, but there are at least some Russian examples.Russian example, Tretyakov Gallery Moscow.

One type of depiction, not usually compatible with correct perspective, concentrates on showing the whole wall and several garden structures or features that symbolize the mystery of Christ's conception, mostly derived from the Song of Songs or other Biblical passages as interpreted by theological writers. These may include one or more temple or church-like buildings, an Ivory Tower (SS 7.4), an open-air altar with Aaron's rod flowering, surrounded by the bare rods of the other tribes, a gatehouse "tower of David, hung with shields" (SS 7.4),"Thy neck is like the tower of David built for an armoury, whereon there hang a thousand bucklers, all shields of mighty men." with the gate closed, the Ark of the Covenant, a well (often covered), a fountain, and the morning sun above (SS 6.10)."Who is she that looketh forth as the morning, fair as the moon, clear as the sun, and terrible as an army with banners?" This type of depiction usually shows the Annunciation, although sometimes the child Jesus is held by Mary.Schiller, pp 53-54
