Introductory Comment

From the perspective of John Plousiadenos, a Greek priest from the island of Crete who wrote this liturgical canon around the year 1464, the Fall of Constantinople in 1453 had hardly spelled an end to the union between the Eastern and Western Churches proclaimed at the Council of Florence in 1439. Not that the issue went without controversy: as he himself suggests in this text, the union of Florence remained controversial on his native island, which was at the time under Venetian control. Hence John’s effort, in composing this piece, to present the Council of Florence and the five doctrinal definitions contained in its decree as orthodox, ecumenical, and binding. He composed this liturgical canon for a prospective liturgical feast celebrating Florence, presumably set for July 6th (the day Florence published its definition). In a manuscript contained in the Barocci collection at the Bodleian in Oxford, we have 22 stanzas, then a prose “synaxarion” giving an overview of the council from a pro-union Greek perspective, followed by a final 14 stanzas. The verses of the canon give a poetical account of the doctrinal content of Florence, and the prose synaxarion gives us John’s obsessive preoccupation with the council’s principal critic, Mark of Ephesus, whom he held responsible for continuing controversy over the union.

A printed edition of this text can be found in Patrologia Graeca, vol. 159, col. 1095-1116. I have also consulted MS Barocci 145 from the Bodelian Library in Oxford, f. 275-279, to correct erroneous readings, fill lacunae, and inform the arrangement of the text.

Greco-Latin Polemic and the Problem of the Single Immersion Baptism

Of the many issues that rose to the fore in the course of the conflicts between the Latin and Greek churches during the Middle Ages, one of the most consistent, and to me, surprising, was the repeated accusation that the Greeks rebaptized Latin Christians when they, for whatever reason, wished to switch their ritual use (what we would now understand as a “conversion” between different denominations). Although the veracity of these claims has been debated, I think, as I have written elsewhere, that there is good reason to believe that the Greeks really did rebaptize Latins. Complaints about the practice began in the mid-11th century with Cardinal Humbert of Silva Candida, who was elsewhere highly accurate in his claims about liturgical practice, and continue well into the 13th century, including an honorable mention in the canons of the Fourth Lateran Council under Pope Innocent III.

What is less clear, though, is why the Greeks were so keen to rebaptize their Latin cousins. It is tempting to see rebaptism as symptomatic of more ethereal theological topics, in which the perceived differences between the two churches was sufficiently great that the Greek clergy (or at least a subset of them) felt the need to mark the reception of these “converts” from heresy by means of the administration of the sacrament. Certainly this understanding had precedent: as early as 325, the canons of the First Council of Nicaea mandated the reception of Paulianists, who were nontrinitarians, by means of baptism. But I think that this understanding is a mistake with reference to the Latin/Greek conflict. Especially in its earlier phase, in the 11th century, there was no general sense of lasting division: the Greeks generally viewed the Latins as wayward brethren to be corrected, not as heretics utterly outside of the Church, and therefore rebaptism can’t be understood as a requirement resulting from serious deficiencies in the faith on the scale of nontrinitarianism.

Rather, I think that these rebaptisms were because of perceived ritual deficiencies in the Latin rite of baptism, and particularly, in the idea that the Latins were prone to using a single immersion when administering the sacrament. And when looking at this possibility we find a much greater incidence of Latin complaint and Greek explanation. Shortly after Cardinal Humbert complained about rebaptisms, Michael Cerularius, the Patriarch of Constantinople, wrote to Peter, the Patriarch of Antioch, that the Latins performed baptism with a single immersion [1]. The two centuries that followed saw repetitions of both: Odo of Deuil, Leo Tuscus, an anonymous Dominican author writing from Constantinople in the mid-13th century, and Jerome of Ascoli (i.e., Pope Nicholas IV) all noted that Latin Christians were being rebaptized. The “Byzantine Lists”, a genre of polemic that enumerated liturgical and cultural “errors” committed by the Latins, again and again returned to the notion that the baptism of the Latin rite was performed through a single immersion [2]. In doing so, the authors of these lists were implicitly invoking another of the canons of the early church, this time from the so-called Apostolic Canons (no. 50): “If any Bishop or Priest does not perform three immersions in making one baptism, but only a single immersion […], let him be deposed” [3]

Assuming that my conclusion is correct, that Greeks rebaptized Latins with some degree of frequency because they believed their form of the sacrament to be ritually defective, the question that next arises is how the Greeks came to hold that belief. Prior to the widespread adoption of affusion or aspersion in the Latin West, the form of baptism appears to have been similar to that of the Greek East: a full triune immersion, done together with the invocation of the persons of the Trinity. We see this clearly referenced as late as the early 13th century, when Pope Innocent III, writing to the Maronite Church, instructs them to invoke the Trinity only once “while completing a triple immersion” [4]. The great exception to the standard Latin practice was the famous license given by Pope Gregory the Great to the church in Spain to baptize with a single immersion as a way to signify the oneness of the Trinity and thereby to combat Arianism. This practice was further codified by the 633 Council of Toledo and its existence confirmed in the works of Isidore of Seville and Ildefonsus of Toledo [5]. The practice is referenced twice more, toward the end of the eighth century, in the letters of Alcuin of York, who acknowledged that the practice existed in certain parts of Spain only long enough to condemn the people who baptize in this way as “neglecting to imitate, in baptism, the three-day burial of our Savior” [6]. They maintain this custom, according to Alcuin, “contrary to the universal custom of the holy Church” making Spain the “wet-nurse of schismatics” [7].

Gregory the Great, the source of the conflict? Antiphonary of Hartker of the monastery of Saint Gall (Cod. Sang. 390, 13 (paginated). Creative Common licensing.

Returning, then, to the polemics of the Greeks, is it possible that their complaints about a Latin single-immersion baptism stemmed from the Spanish practice? I see no other possible cause, although this feels unsatisfactory as an explanation. At most, the single-immersion baptism was a regionalism confined to the Iberia, and the opposition of Alcuin, the great champion of Romanization in the West, makes it unlikely that it would ever have spread further than its native peninsula. Indeed, the gradual imposition of the Roman rite throughout the Christian West likely reduced the frequency of single-immersion baptisms within Spain itself in the centuries following the initial permission of Pope Gregory. If the practice survived at all by the mid-11th century, when Cardinal Humbert and Patriarch Michael wrote their respective complaints – and I haven’t found any evidence from that time for or against – it would probably have been a very rare indeed for someone baptized “incorrectly” to have been found in Constantinople.

Pending further evidence, then, we are left with the Greeks reacting at most to an improbability, and more likely to outdated information. While I fully acknowledge that it’s no more than supposition on my part, my best guess is that the works either of Gregory the Great or of Isidore of Seville (or of both, or of someone else entirely) were received in the theological circles of 11th-century Constantinople, leaving the mistaken impression that the practice of single immersion baptism was common in the West. From there, the notion that the Latins performed this sacrament incorrectly, along with most of the others, proved hard to dislodge.

Distilling Tradition: Anglo-Saxon Botany and the Beginning of Gin

Since moving to England, I’ve become very fond of gin, and the medievalist in me was thrilled when I was recently gifted a bottle of Ad Gefrin Distillery’s Thirlings Dry Gin. The gin is inspired by Northumbria’s Anglo-Saxon roots, what Ad Gefrin describes as “a time of welcome, celebration, and hospitality,” and it has been crafted with “a Northumbrian heart and Anglo-Saxon soul.”[1]  

The gin is gorgeous, both in its presentation and its finish. The bottle itself embodies the location’s Anglo-Saxon heritage: “Far from just being a vessel for the spirit, the bottle tells its own authentic story. The stepped punt reflects the 7th Century wooden Grandstand discovered on the ancient site and the holes/dimples in the glass represent the post holes which identified where the royal complex of buildings were and enabled archaeologists to calculate their size and height.”[2] Its botanical profile is comprised of “flavours inspired by Northumberland, heather and pine from the Cheviot hills, elderberry and dill from the hedgerows, and Irish moss and sea buckthorn from the coast.”[3] But the base of all gins, of course, is juniper.

In addition to its distillery that produces both gin and whisky, Ad Gefrin offers an impressive collection of Anglo-Saxon artefacts and an immersive experience of Northumberland’s Golden Age, including the richness and hospitality of the medieval hall. Photo courtesy of Ad Gefrin.

Juniper, a type of coniferous evergreen, is native to various parts of the northern hemisphere. There are approximately 30 species, but the common European species, Juniperus communis, is described as “a hardy spreading shrub or low tree, having awl-shaped prickly leaves and bluish-black or purple berries, with a pungent taste.”[4] These berries form the base of gin’s distinctive botanical flavor, which the Craft Gin Club aptly describes as “[r]esinous, piney and fresh on the palate and nose.”[5]

Juniper berries begin green but adopt a deeper blue to purple-black color as they mature. Common juniper is native to most of the northern hemisphere, including the United Kingdom. According to the Woodland Trust, the plant “thrives on chalk lowland, moorland, in rocky areas and old native-pine woodland” and functions as a source of food and shelter for a variety of birds.

The Anglo-Saxons recognized juniper primarily for its medicinal properties. Its Old English name was cwic-beam, which literally translates to “life-tree.”[6] In the Old English Herbarium, a popular medieval treatise dedicated to the identification and application of plants, juniper is listed as sabine or savine in accordance with its Latin name, Juniperus sabina. As a compilation and translation of originally separate Latin treatises, the Herbarium employs Latin alongside English, much in the same way modern medical textbooks maintain Latin terminology for conditions that are then described in English.

The treatise indicates that juniper can be used to treat “painful joints and foot swelling,” “headache,” and “carbuncles.”[7] In the first instance, the treatise advises that the plant be concocted into a drink; the entry reads: “For the king’s disease, which is called aurignem in Latin and means painful joints and foot swelling in our language, take this plant, which is called sabinam, and by another name like it, savine, give it to drink with honey. It will relieve the pain. It does the same thing mixed with wine.”[8] Here, the king’s disease – in Old English, “wiþ þa cynelican adle”– likely refers to jaundice related to gout.[9] For the treatment of headache, the plant was to be mixed into a kind of poultice and applied to the head and temples.[10] In the case of carbuncles, which refer to a cluster of boils, the plant would be made into a honey-based salve and applied to the infected area.[11]    

Entries for chamomile and heart clover in the only surviving illustrated Old English herbal, a book that primarily describes plants and their applications. As the British Library notes, “Remedies for poisonous bites were marked out with drawings of snakes and scorpions.” The manuscript, produced in England and dated 1000-1025, also contains information on animals and their medicinal properties, though not all of its contents are reliable. (British Library, Cotton MS Vitellius C III, f. 29v).

While juniper was available to the Anglo-Saxons, even in drinking form, distilling was not. In fact, distilled liquors were virtually unknown in medieval England.[12] Rather than spirits, the early medieval English drank beer and mead.

According to John Burnett, “Beer was probably the first drink deliberately made by man.”[13] In his book, Liquid Pleasures: A Social History of Drinks in Modern Britain, Burnett explains that beer brewed from fermented barley has been recorded as far back as the third millennium B.C. in the Bronze Age civilizations of Egypt and Mesopotamia, and beer production became common across Europe during the Celtic Iron Age.[14] In its earliest use, the Old English beor, “beer,” likely referred to any type of alcohol produced through fermentation, though it appears have been distinct from the less frequently used ealu, “ale.”[15] Beor may have referred to drinks brewed from malt, while ealu may have been a sweeter and stronger drink.[16] These terms may also have been used interchangeably until hops were introduced much later in the medieval period.[17]

The introduction of hops to the brewing process distinguished ale from beer; it also displaced women as the primary producers of the beverage. As A. Lynn Martin explains, “In England ale brewing was a domestic industry dominated by alewives. Their brew was usually sweet, sometimes flavored with herbs and spices, and spoiled if not consumed within several days. The addition of hops created a bitter drink that was stronger and lasted longer than ale.”[18]

Mead, however, was the predominant drink of the Anglo-Saxons and was made by fermenting a mixture of honey and water. The Old English word for “mead” is the same for “meadow”: medu, effectively evoking the beverage’s connection to the flowers and bees essential for the production of honey and, in turn, mead. The plant now known as meadowsweet, or medu-wyrt in Old English, was also sometimes used to flavor the drink.[19]

Additionally, the Anglo-Saxon hall was commonly called the medu-hall, or “mead hall,” indicating not only a primary attribute of the hall but also the centrality of the drink to Anglo-Saxon culture. The hall was an integral part of early medieval English society and functioned as a space for social and political discourse, as well as communal gatherings and feasting celebrations. Indeed, the speaker of the Old English elegy known as The Seafarer describes his loneliness in relation to the absent sounds of the hall, which function as a synecdoche for the communal bonds he craves: “A seagull singing instead of men laughing, / A mew’s music instead of meadhall drinking.”[20]  

Dated to the 5th century, this glass Anglo-Saxon drinking vessel, known as the Castle Eden Claw Beaker, was found at Castle Eden in Durham, England. The object is currently on display at Ad Gefrin’s Wooler Museum, on loan from the British Museum, and returned to the North East after more than 30 years.

Because honey was used for a variety of purposes, including the making of both mead and medicine, beekeeping was also an important part of Anglo-Saxon society. In fact, sugar was not produced in medieval England, so honey was the primary sweetener, which is why it appears so frequently in culinary and medical recipes alike. The Old English “Charm for a Swarm of Bees,” a metrical incantation, serves as evidence of honey’s necessity. Essentially, the charm is a magic spell meant to entice a swarm of bees to a keeper and encourage them to remain:  

Charm for a Swarm of Bees

For a swarm of bees, take earth and throw it down with your right
hand under your right foot, saying:

I catch it under foot—under foot I find it.
Look! Earth has power over all creatures,

Over grudges, over malice, over evil rites,
Over even the mighty, slanderous tongue of man.

Afterwards as they swarm, throw earth over them, saying:

Settle down, little victory-women, down on earth—
Stay home, never fly wild to the woods.
Be wise and mindful of my benefit,
As every man remembers his hearth and home,
His life and land, his meat and drink.[21]

Eventually, mead went by the wayside, and wine became the more popular drink near the end of the Anglo-Saxon period – at least among the wealthy. As Burnett points out, while the consumption of wine was relatively high throughout the Middle Ages, “it never rivalled beer as the drink of the masses.”[22] 

By the 16th century, distilled drinks were “beginning to be served together with sweetmeats at the end of banquets as pleasurable, stimulating aids to digestion.”[23] Distillation describes the process of heating a liquid into a vapor, which is then condensed into a pure essence, and the procedure may have been known to the Chinese as early as 1,000 B.C.[24] Burnett explains that the “the requisite knowledge was brought to the West either by the Cathars or by returning Crusaders, who had seen distillation practised by Arab alchemists. A coded recipe for ‘aqua ardens’ appeared in a French monastic tract about 1190 alongside one for artificial gold, and through the medieval world spirits were regarded as mysterious, even magical, substances, used only medicinally for their stimulating, reviving qualities.”[25]

He continues: “English records of ‘aqua vitae’ distilled from wine appear in the fourteenth century, when it was made by monks and apothecaries, and became more widely known during the Black Death (1348-9) as a warming prophylactic. Spirits were also redistilled with herbs and flowers from the physic gardens of monasteries to make a variety of liqueurs with therapeutic properties, while in private households spirit-based ‘cordials’ were recommended for the treatment of palsey, the plague, smallpox, apoplexy, ague and other diseases.”[26]

Gin, from the Dutch genever, or “juniper,” because it was distilled with the plant’s berries, started being imported into England from the Netherlands during the late 16th century. The original product was “a highly flavoured, aromatic drink” that is still produced in the Netherlands and typically enjoyed neat.[27] By the mid-18th century, however, England had begun producing its own version in London, which was “less coarse and more subtly flavoured.”[28] By this time, spirits were being consumed largely for pleasurable, rather than medicinal, purposes.

While gin and distillation were not known to the Anglo-Saxons, juniper certainly was, and in this way, the spirit’s botanical roots are intertwined with medieval English history.
