Call the medieval midwife

Tucked away in a 14th-century encyclopaedia and bestiary is an oath written alongside a black cross. The person who made it had borrowed the book, and identified themselves as ‘abestetrix', echoing the Latin ‘obstetrix’, meaning ‘midwife’. (Another hand has glossed this as 'heifmoeder’.) Midwifery was as vital in the medieval world as it is today. Medieval manuscripts can provide a variety of evidence for the hardships, mysteries and triumphs of this historic profession.

Accounts of famous births from history are often accompanied by illustrations of the birthing chamber, depicting midwives and their female companions. This image accompanies the account of the birth of St Edmund in John Lydgate's Lives of Saints Edmund and Fremund. The new mother lies in bed, tended by her companions, while the baby is warmed before the fire.

The caesarean birth of Julius Caesar is frequently illustrated in medieval accounts of his life. Many of these illustrations depict men performing the caesarean, most likely because of the more surgical nature of the procedure. However, it may not have been uncommon for midwives to perform a caesarean themselves. These two illustrations of Caesar's birth depicts a midwife pulling the baby from the mother, accompanied by a female attendant, and the same birth, with a man playing the midwife's role.

Information on pregnancy and childbirth was also included in medical treatises. Copied into one 15th-century manuscript is a gynaecological text taken from Gilbertus Anglicus’ Compendium of Medicine. The text is accompanied by illustrations of foetuses in the womb, depicted in a variety of unusual positions. It is difficult to determine whether this work would ever have been consulted by a woman. The manuscript's first known owner was Richard Ferris, sergeant surgeon to Elizabeth I, the queen who famously never married or had children.

Books may not have been an unusual sight in the birthing chamber, as women were known to have had texts read aloud to them while they were in labour. The Passio of St Margaret was a popular choice. St Margaret is thought to have emerged from a dragon's womb ‘unharmed and without any pain’, and came to be widely regarded as the patron saint of women in childbirth. Many manuscripts of the Passio of St Margaret are accompanied by instructions to bless the expectant mother with a copy of the Passio to secure the safe delivery of her child.

In the 14th century, relics of St Margaret’s girdle were often used as birthing aids. One 15th-century amulet roll (Harley Ch 43 A 14), which is thought to have been used as a birth girdle, contains a text in Middle English invoking the protection of the Cross, specifically referencing childbirth. This invocation was likely read aloud, perhaps by the midwife, as the girdle was worn by the expectant mother. Invocations to aid pregnancy and childbirth were also used in the Anglo-Saxon period. The Old English Lacnunga contains a charm to be used by women who struggled to carry a child to term. The text includes a set of prose introductions and a series of short poems intended to be recited aloud in a ritual process: 

Se wífman, se hire cild áfédan ne mæg, gange tó gewitenes mannes birgenne and stæppe þonne þríwa ofer þá byrgenne and cweþe þonne þríwa þás word:
þis mé tó bóte þǽre láþan lætbyrde,
þis mé tó bóte þǽre swǽran swǽrbyrde,
þis mé tó bóte þǽre láðan lambyrde.

'Let that woman who cannot nourish her child walk to the grave of a departed person and then step three times over the burial, and then say these words three times:
this as my remedy for the hateful late birth, this as my remedy for the oppressive heavy birth, this as my remedy for the hateful lame birth.'

(translated by Elliott Van Kirk Dobbie, The Anglo-Saxon Poetic Records: A Collective Edition (New York, 1942))

A detail from a medieval manuscript, showing the text of an Old English charm for 'delayed birth'.

A charm for ‘delayed birth’ in Lacnunga: Harley MS 585, f. 185r

It is difficult to prove that midwives were literate or regularly consulted texts in the medieval period. However, many medical manuscripts often included information regarding childbirth and the written word was certainly not out of place in the birthing chamber. The midwife who made the oath to return the book may not have been the only member of her profession to be borrowing books in the 14th century.

Leonardo da Vinci on the Moon

One of the great thrills of curating our blockbuster exhibition, Harry Potter: A History of Magic, has been choosing the exhibits and revisiting some of our favourite manuscripts. When we were planning the show, I often used to impress people by mentioning certain of the books and objects we were intending to display: medieval manuscripts, Chinese oracle bones and, oh yes, something written by somebody called Leonardo da Vinci, "you may have heard of him?" At this point heads always turned, and I knew we'd captured everyone's attention.

So what exactly was I talking about, when I mentioned that Leonardo's writings would be featured in the exhibition? You may be aware that Leonardo da Vinci (1452–1519), the great inventor, scientist and artist, made copious notes throughout his career. These were gathered into a series of notebooks, one of which is today preserved at the British Library in London, where it is known as the ‘Codex Arundel’ (after a former owner, the Earl of Arundel): its shelfmark is Arundel MS 263 and it can be viewed in its entirety on our Digitised Manuscripts site. The notes are written in Italian, and if you examine the writing closely, you immediately recognise that they are in Leonardo's characteristic mirror handwriting, reading from right to left.

Leonardo da Vinci's notebook (Italy, c. 1506-08): Arundel MS 263, f. 104r

One page from Leonardo's notebook seemed particularly appropriate to show in the Astronomy room of Harry Potter: A History of Magic, alongside objects such as an Arabic astrolabe and the oldest surviving manuscript which charts the night sky (made in China around the year AD 700). The diagram shown here describes the reflection of light, according to the alignments of the Sun, Moon and Earth. Leonardo da Vinci’s illustration shows the Sun and Moon revolving round the Earth, accepting the theory popularised by the Greek astronomer, Ptolemy (d. c. AD 170), that the Earth occupied the centre of the universe. Leonardo was writing, of course, approximately 100 years before the invention of the telescope.

On the right-hand side of this page are two diagrams showing the Earth and Moon. The second of these supports Leonardo's belief that the Moon was covered with water, and that its surface would operate like a convex mirror, reflecting light. We may no longer believe this to be true (everyone knows that the Moon is made of cream cheese) but it's always fascinating to get a first-hand insight into the mind of a genius such as Leonardo da Vinci. Placing his notebook on display in our Harry Potter exhibition has enabled more of our visitors to come face-to-face with this intriguing document. Maybe we will have inspired some of the astronomers and scientists of the future, who have been coming to see the exhibition in their thousands.

Harry Potter: A History of Magic is on show at the British Library in London until 28 February 2018. There has been a huge demand for tickets, so we strongly urge you to book in advance of your visit.

You cannot be Sirius

Fans of a certain boy wizard will be familiar with Sirius Black, Harry Potter’s beloved godfather. In the Harry Potter books, Sirius Black was an Animagus, with the ability to turn into a shaggy-haired black dog. This is no coincidence, as his name was inspired by Sirius, the brightest star in the night sky, which lies in the constellation known as Canis major (The Greater Dog). The British Library's exhibition Harry Potter: A History of Magic explores the history, mythology and folklore behind the Harry Potter stories, and we are delighted that it features a wonderful 12th-century astronomical treatise (Cotton MS Tiberius C I), containing an elaborate illustration and description of the constellation Sirius.

Image 1_cotton_ms_tiberius_c_i_f028r

The constellation of Sirius the Dog Star, from Cotton MS Tiberius C I, f. 28r

This manuscript was produced at the Benedictine abbey of St Peter, St Paul and St Andrew in Peterborough, sometime in the early decades of the 12th century. The astronomical treatise it contains is known as the Aratea, being a Latin translation (by Marcus Tullius Cicero) of the Phaenomena by Aratus of Soli. The description of each constellation is accompanied by a pen-drawing of either human or animal figures, with red dots representing the stars. In this instance, the constellation Sirius takes the shape of a dog, with the words written in black ink.

The body of Sirius (and the other figures in this manuscript) is infilled with an account of the origins and history of each constellation. They comprise quotations from the Astronomica written by Hyginus, an astronomical source-book. Sirius, from the Greek seirios aster, meaning ‘scorching star’, was thought to have been named by the Egyptian goddess Isis, because the star shone more brightly than any other. The dog days of summer were so-called because the hottest days of the year traditionally coincided when the Dog Star ascended to rise before the Sun, from late July until August.

Image 2_cotton_ms_tiberius_c_i_f027v

The constellation of Orion, from Cotton MS Tiberius C I, f. 27v

Sirius was also said to be the hunting dog of Orion. The constellation Orion is portrayed in the same manuscript as a man inside a house. According to the Astronomica of Hyginus, Orion was accidentally slain by the goddess Diana, as the result of a challenge that she could not hit him with one of her hunting arrows. To mourn his death, she placed him among the constellations. Bellatrix, meaning ‘female warrior’, is the third brightest star in the Orion constellation. Other figures in the night sky include the Hare, the Eagle, the Swan and the Centaur. The last-named was believed to be highly skilled in augury, that is, the interpretation of omens.

Image 3_cotton_ms_tiberius_c_i_f031v

Would you like to stargaze more? This illustrated Aratea has been digitised by the Polonsky Foundation England and France, 700-1200 project. It is now available to view online on our Digitised Manuscripts site. Two other copies of the Aratea can also be seen in full there, one made in 9th-century France and later taken to Canterbury (Harley MS 647) and the other made at Fleury around the year 1000 (Harley MS 2506).

Meanwhile, the wonderful manuscript illustrated above is currently on display in the Astronomy section of the British Library’s major exhibition, Harry Potter: A History of Magic. Tickets can be purchased online, but they are selling extremely fast. The show has to end on 28 February, so catch it while you can.

British Library manuscripts in Glass exhibition at the Musée de Cluny

Two British Library manuscripts are featured in the exhibition, Le Verre, un Moyen Âge inventif (‘Glass, the Inventive Middle Ages’), at the Musée de Cluny in Paris, which opened on 20 September and runs until 8 January 2018. A collection of miniatures from a treatise on the Vices and Virtues and a 13th-century copy of Roger Bacon’s Opus Maius are two of nearly 150 objects that include glassware, illuminated manuscripts, engravings and paintings as part of an examination of the use of glass throughout the Middle Ages.

Image 1_add_ms_27695_f014r

Miniature of a tavern scene with men drinking illustrating Gluttony, and below a cellarer passing up a drink, from a treatise on the Vices and Virtues (fragment), Genoa, c. 1330–1340: Add MS 27695, f. 14r

The scene above is an image originally bound with a 14th-century treatise on the Seven Vices (now Add MS 27695) by a member of the Cocharelli family of Genoa. Possibly used to instruct the children of the family on the seven deadly sins, the painting depicts four men representing Gluttony as they drink in an Italian tavern. The scene also features a variety of glassware: the moderate drinker on the left sips from a glass, the excessive drinkers beside him both drink from bottles and glass, and the drinker on the right has dropped his bottle as he vomits. The cellarer below is passing the drinkers a refilled glass, and his additional glasses are visible on a shelf beside him.

During the 14th century, northern Italy was a leading centre in the production of glass for domestic and scientific use. Venetian glassmakers specialised in making high quality, colourless glassware made from quartz pebbles from the Italian mainland and plant ash from Egypt and Syria. By the Renaissance, the glass industry of Venice was booming with spectacular glassware used to celebrate special occasions across Europe. As prized status symbols in events such as the marriage ceremonies of noblemen and women, Venetian glassware featured opulent glass imitating semiprecious stones, gilding and enamelling.

As well as domestic glass, medieval glass was used to create scientific apparatuses and invent life-changing tools. The 13th-century English friar and scholar Roger Bacon produced major works on natural philosophy and mathematics, including the Opus Maius, which he sent to the Pope in 1267 or 1268. In this treatise of over 800 pages, Bacon examined topics ranging from celestial bodies to gunpowder. The British Library holds what is thought to be the earliest manuscript copy of several of Bacon’s works (now Royal MS 7 F VIII). This copy features the text of Bacon’s work on optics known as the Perspectiva, in which he describes the properties of light, colour and vision. His study of mirrors and lenses greatly influenced the scientific community, leading to the invention of reading glasses and magnifying glasses. In 1289, the Florentine writer Sandro di Popozo commented in a treatise on the conduct of family that, ‘I am so debilitated by age that without the glasses known as spectacles, I would no longer be able to read and write.’

How to harvest a mandrake

As a general rule, we don't normally give gardening advice on the Medieval Manuscripts Blog. It's just possible, however, that you may have been contemplating the best way to harvest a mandrake. And so here we provide you with some handy tips on cultivating this most notorious of plants, based on manuscripts in the British Library's collections.

A cure for insanity

In the Middle Ages, it was believed that mandrakes (mandragora) could cure headaches, earache, gout and insanity. At the same time, it was supposed that this plant was particularly hazardous to harvest, because its roots resembled the human form; when pulled from the ground, its shrieks could cause madness.

MANDRAKE ROOT low-res

Identify your mandrake

You would think this was simple, but it was long believed that there were two different sexes of mandrake (which we have always been tempted to call the 'mandrake' and 'womandrake'). This beautiful 14th-century manuscript was on show in the British Library's Harry Potter: A History of Magic exhibition. It contains an Arabic version of De materia medica, originally written in Ancient Greek by Pedanius Dioscorides, who worked as a physician in the Roman army. Dioscorides was one of the first authors to distinguish (mistakenly) between the male and female mandrake, as depicted here. In fact, there is more than one species of mandrake native to the Mediterranean, rather than two sexes of the same plant.

Or 3366_0299

This mandrake, on the other hand, is quite clearly (ahem) the male of the species ...

C13579-82

Below are two mandrakes, one male, one female, drawn in the lower margin of the Queen Mary Psalter — hanging upside down, their blood is clearly rushing to their heads.

G70035-40

It's also advisable not to confuse your mandrake with a gonk, with an elephant (yes, they are elephants), or with a dragon.

Sloane_ms_278_f048v

Bring a dog

Medieval plant-collectors devised an elaborate method to harvest mandrakes. The best way to obtain one safely was to unearth its roots with an ivory stake, attaching the plant to a dog with a cord. A horn should then be sounded, drowning out the shrieking while at the same time startling the dog, causing it to drag out the mandrake. This medieval mandrake looks resigned to its fate.

Harley_ms_1585_f057r

While this mandrake is blushing with shame at the prospect of being pulled out of the ground ...

This Anglo-Saxon hound has yet to be tied to the mandrake (is that a ball that has distracted it attention?).

Cotton_ms_vitellius_c_iii_f057v

Stuff your ears with earth

Another trick was to stuff your ears with clods of earth before attempting to pull the mandrake from the ground. The gentleman in the red cap below has done exactly this, and is blowing resoundingly upon his horn: perfect technique!

Science Museum loans in Harry Potter: A History of Magic

There are some stunning medieval manuscripts in the British Library's current exhibition, Harry Potter: A History of Magic. We have spent the last year searching our collections for items that relate in some way to the magical subjects studied at Hogwarts School of Witchcraft and Wizardry, and we've made some incredible discoveries along the way. But no exhibition of this magnitude is complete without the assistance and generosity of other institutions. Visitors to the show will recognise instantly that our books are complemented by a wealth of fascinating objects, many of which have kindly been loaned by our friends at the Science Museum in London. We would like to record here our gratitude to the assistance provided by both the Science Museum and the Wellcome Trust in enabling us to borrow these items, which have helped to make our exhibition such a magical experience. Which is your favourite? The mandrake root, perhaps, or the unicorn shop sign?

We are also delighted to announce that, on 12 December, Roger Highfield and Sophie Waring of the Science Museum will be delivering one of our Hogwarts Curriculum Lectures on the subject of Alchemy. You can book your tickets here. It promises to be a very special evening. Roger has also contributed a wonderful essay on Potions and Alchemy to the exhibition book, published by our friends at Bloomsbury. That's well worth a read, though we'd love you to be able to make it to the exhibition in London as well. It closes on 28 February, and tickets need to be purchased in advance.

MANDRAKE ROOT low-res

A mandrake root: this mandrake root dates from the 16th or 17th century, and it has been carved to resemble the figure of a human. The mandrake's resemblance to the human form has prompted many cultures over the centuries to attribute special powers to the plant. In reality, the mandrake’s root and leaves are poisonous and it can induce hallucinations.

L0058635

A real bezoar stone: a corruption of the Persian word pādzahar (pād, expelling; zahar, poison), bezoars were first introduced into medieval Europe by Arabic physicians and reputedly provided a powerful antidote to poison. Wealthy owners (including kings and popes) spent considerable sums on acquiring the stones (digested by goats and similar animals), and often kept them in elaborate cases.

L0036765

Apothecary jars: we love these apothecary jars, which were possibly made in Spain in the 17th century. The jar labelled ‘Vitriol Coerul’ contained copper sulphite, ‘Ocul. Cancr’ stored ‘crabs eyes’ — particles from the guts of putrefied crayfish, used to cure indigestion — while the jar named ‘Sang. Draco.V.’ contained ‘Dragon’s Blood’, a potent red resin that still has medical uses today.

Apothecary_Sign

An apothecary's sign: the blood, hair and horn of the unicorn have been traditionally believed to possess powerful medicinal properties. This sign would have stood outside an apothecary’s
shop in the 1700s. The horn is made from the tusk of a narwhal, otherwise known as the ‘unicorn of the sea’.

MiniatureOrrery_1924-0471_(0001)

A miniature orrery: an orrery is a mechanical model of the solar system, often used for teaching. This miniature orrery was made in London in the 18th century by the mathematical instrument maker, John Troughton. It displays the movement of Earth in relation to the Moon and two other planets.

Prepare to be spellbound

As a general rule, we don't like to start our blogposts with the words, 'We are delighted to announce'. But there's always an exception, and this is it! We are delighted to announce that the British Library's amazing new exhibition, Harry Potter: A History of Magic is now officially open to the public.

Our exhibition celebrates the 20th anniversary of the first publication in the United Kingdom of J.K. Rowling's Harry Potter and the Philosopher's Stone, originally released in 1997. But, in a new departure, the exhibition also examines the history, mythology and folklore that lie at the heart of the Harry Potter stories. As well as original drafts and drawings loaned by J.K. Rowling herself, alongside artwork by Jim Kay (who is illustrating the Harry Potter books for Bloomsbury), you'll find on display a range of glorious items from the British Library's own collections, including Chinese oracle bones, papyri and a host of medieval manuscripts.

Harry-potter-ripley-scroll

The Ripley Scroll, dating from around 1600, and explaining how to make your very own Philosopher's Stone. The entire manuscript, all 5.9 metres of it, is on display in the exhibition.

Tickets are selling fast — this Potter thing might just catch on one day — but we'd love you to visit London to see the show in person between now and its final day, 28 February. In the meantime, here is a sneak preview of some of the manuscripts you'll be able to see.

Harry-potter-abracadabra

How to protect yourself against malaria? Write out the word 'abracadabra' repeatedly on a piece of parchment (it's obvious when you think about it).

Harry Potter: A History of Magic is on at the British Library from 20 October 2017 to 28 February 2018. Tickets can be purchased here. The exhibition has been staged by the British Library in partnership with The Blair Partnership (representing J.K. Rowling) and Bloomsbury Publishing, with the kind assistance of Pottermore and Google Arts and Culture, and the generosity of numerous lenders.

The exhibition books Harry Potter: A History of Magic and a version designed especially for younger people, Harry Potter: A Journey Through the History of Magic, are available to buy through the British Library's online shop. (They're quite good, really: note to reader, I helped to write them.)

Fragmentarium and the burnt Anglo-Saxon fragments

Have you ever been intrigued by the survival of fragments of medieval manuscripts, used perhaps as waste in later bookbindings, or damaged in catastrophic events such as the Ashburnham House fire? The recent launch of Fragmentarium (the Digital Research Laboratory for Medieval Manuscript Fragments) will enable many of these fragments to be analysed in greater detail, and in some cases to be digitally reunited. The British Library is one partner in this project, alongside institutions and collections from Austria, France, Germany, Greece, Italy, Norway, Switzerland, the USA, the Vatican and the United Kingdom. As the project states, 'Fragmentarium enables libraries, collectors, researchers and students to publish images of medieval manuscript fragments, allowing them to catalogue, describe, transcribe, assemble and re-use them.'

Some of our readers may have come across the story of the Ashburnham House fire of 23 October 1731. This tragic event left a number of manuscripts in the famous collection of manuscripts assembled by Robert Cotton in an extra-crispy state. After a remarkable conservation effort undertaken in the 18th and 19th centuries, many of these volumes did not look so bad, all things considered, as you can see for yourself with Beowulf. But some of these manuscripts did not fare so well — to the naked eye they often resemble something approaching a burnt biscuit!

The burnt Cotton fragments are among the most evocative artefacts of medieval culture, both for the tragedy of their destruction and the mystery of their contents. Many of the surviving leaves remain critical to scholarship, often containing unique texts or their earliest known copies. Work on other fragments at the British Library has already shown that multispectral photography can make it possible to extract more information from what survives. The burnt leaves remain vulnerable, and so it is critical that digital techniques be used to document and preserve their present state.

Cotton MS Otho A X, f. 1v: a blend of photographs taken across light spectra

For several decades, technology has been applied to improve the readability of the Cotton fragments. In the early 1950s, ultraviolet photography was applied to Æthelweard’s Chronicle (in Cotton MS Otho A X and Cotton MS Otho A XII) in order to make new sense of a handful of pages. The same process was also used with Cotton MS Otho A I. At the time, however, these photographs did not achieve wide dissemination due to the limitations of publishing in print.

The recent application of multispectral photography has enabled us to recover more details of these fragments, and with reconstructed colour. At the same time, regrettably but inevitably, this technology has revealed that, in the course of half a century, the condition of these fragments has sometimes deteriorated. A few volumes that seemingly could be read without technological assistance only a few decades ago have details that today are difficult to read with the naked eye. In some cases, the volumes are so fragile that they can only be issued in the British Library's Manuscripts Reading Room with special curatorial permission.

We are currently publishing key remnants of some of the burnt Anglo-Saxon manuscripts in the Cotton collection on Fragmentarium. Dr Christina Duffy, the British Library's Imaging Scientist, has photographed over a hundred of these fragments and has skilfully processed them to make their reconstruction as legible as possible. The results will be available under a Creative Commons Public Domain Dedication. Fragmentarium has also built the capacity into their site to handle multiple images of a single folio — rare but critical functionality for dealing with multispectral imaging, since the images you will see are a scientific but also very much a human reconstruction.
