The Charter of Liberties

A copy of the Coronation Charter of Henry I/Charter of Liberties

When William Rufus died, his younger brother Henry assumed the throne. It should have gone to the oldest brother, Robert Curthose, who was away on the First Crusade, because of an agreement between William and Robert. After all, when their father died, Henry was given a chunk of money; he wasn't even given a plot of land to rule the way Robert was given the dukedom of Normandy and William got England. The nobles didn't want to accept Henry at first. It was probably the Charter of Liberties that changed their minds.

The Charter of Liberties is also known as the Coronation Charter. It is the earliest extant coronation charter from England. In it, the new king makes promises to uphold laws. The statements made in this particular Charter were popular because they undid many of the acts of William that were unpopular.

For instance, statement 1 promises that Henry "shall not take or sell any property from a Church upon the death of a bishop or abbot, until a successor has been named to that Church property." (William had left the position of Archbishop of Canterbury lie vacant after the death of Lanfranc, so that he could appropriate the revenue from the archbishop's lands.)

Statement 6 forgives "all debts and pleas which were owing to my brother, except those which were lawfully made through an inheritance."

Statement 8 reverses the practice of being forced to bribe the king: "If any of my barons commit a crime, he shall not bind himself to the crown with a payment as was done in the time of my father and brother, but shall stand for the crime as was custom and law before the time of my father, and make amends as are appropriate."

Other statements put more control in the hands of the barons, and promise that the Crown shall not act rashly. When Robert Curthose went on the First Crusade, William gave him 10,000 marks—the equivalent of 25% of the annual royal budget. William got this money from a very heavy tax levied on the whole of England.

Even though in the normal course of events Henry would not have been part of the succession, the Charter of Liberties presented at his coronation helped to "sell" him to the noble class.

Ralph Flambard, Robert, and Henry

The Battle of Tinchebray

When Ralph Flambard escaped from the Tower of London, he fled to Normandy to the court of its duke, Robert Curthose. Robert was the eldest son of William the Conqueror who failed to inherit the throne—twice. The first time was when he rebelled against his father, later seeing the throne going to the second eldest, William Rufus. The second time was when, despite an agreement with William Rufus to be his heir, Robert was on Crusade when William died, giving younger brother Henry the opportunity to take the throne.

Flambard convinced Duke Robert that he should assert his claim to the throne (despite Robert's agreement to not pursue it in exchange for 3000 marks/year). With Flambard organizing the fleet, Robert's army landed in England in July 1101. It didn't go well. Henry's army was larger, and England didn't really want another change on the throne, so the local support was all for Henry.

Within a couple weeks of landing, on 2 August, Robert and Henry agreed to the Treaty of Alton—Alton was where Henry's army met and stopped the advance of Robert's—in which Robert (again) agreed to renounce any claim to the throne of England in exchange for an annual payment. Flambard, no doubt part of the negotiating force, actually got reinstated as Bishop of Durham! But he chose to stay in Normandy for five years: Robert had thanked him for his help by granting him the see of Lisieux

In 1105, however, Henry broke the agreement. Despite the Treaty of Alton, Henry invaded Normandy and fought against his brother in the Battle of Tinchebray. Robert was captured and imprisoned (he died in 1134, in Cardiff Castle). After the battle, Flambard made his peace with Henry, returned to England, and took up responsibility for Durham again.

Back in England, Flambard continued major building projects: a cathedral, a defensive wall around Durham Castle, Norham Castle, and more. He died on 5 September 1128.

The First Prisoner

Ralph Flambard was born in Bayeux, Normandy six years before William the Conqueror crossed the English Channel and became King of England. When he grew up, however, he became intertwined with the affairs of William and his sons.

He must have been a clever lad, because he was one of the people put in charge of the Domesday Book in 1086, to make an account of all the lands and towns in England. He also became the keeper of the king's seal; documents had to pass through him to be stamped as official. When William died, Ralph chose to serve the new king, William Rufus.

Under Rufus, Flambard showed notable talent at raising funds for the king—and himself. He took control of empty parishes (up to 16 at one point), so that rent from their tenants flowed to him. With the money he was raising for the Crown, he built the first stone bridge in London (but not London Bridge itself). It was at this time that the king's hall was built in Westminster, the walls of which are still standing.

When William Rufus died in 1100, Ralph Flambard, now Bishop of Durham, was made a scapegoat for the financial hardships put on the citizens of England. King Henry I made Flambard the first person to be imprisoned in the Tower of London.

He also became the first man to escape the Tower of London.

The story goes that his friends sent to him a large jug of wine. (Prisoners in the Tower were not fed well, and food and drink from family and friends were allowed in order to sustain them.) Inside the jug was a rope. Flambard offered his captors wine, and when they were drunk and sleeping, he extracted the rope, tied it to the middle strut of the window, and climbed down to where his friends were waiting with horses to take him and his elderly mother to a boat that would whisk him to safety in Normandy.

Archbishop Anselm of Canterbury arranged a papal trial for the crime of simony. Henry officially confiscated his lands. Archbishop Gerard of York took away his title of bishop. Flambard didn't care: he had had dealings with every important member of William the Conqueror's family except one—the out-of-favor eldest son, Robert Curthose. He made his way to Robert, the Duke of Normandy; he had a plan.

Sibling Rivalry

When William the Conqueror died in 1087, he decided to leave the throne of England to his second eldest, William Rufus. To his eldest, Robert Curthose, who had once rebelled against him, he left the Duchy of Normandy. (Robert hadn't even come to his father's deathbed, staying on the continent because of the bad blood between him and his family.) The youngest son, Henry, got £5000 silver (and two smaller provinces in France: Maine and the Cotentin Peninsula). William and Robert, as the two major landholders, agreed to make each other their heir.

That didn't last.

Months later, several barons decided to revolt against William Rufus in the Rebellion of 1088. Robert joined them. Verbally. He never actually traveled to England to take part in the rebellion with any troops; had he done so, the rebellion might have succeeded. As it happened, William invaded Normandy a few years later, capturing large parts of the Duchy from Robert.

They managed to reconcile, however, when they decided to team up and expand both their property holdings by taking Maine and Cotentin away from their younger brother, Henry. Henry lost the Cotentin (an important coastline on the English Channel) after a two-week siege, retaining only the smaller and now land-locked Maine.

William died in a hunting accident on 2 August 1100. At the time, Robert was returning from the 1st Crusade. He hurried back to England to claim the throne because of the agreement he had with William since 1087. Unfortunately for him, Henry was in a position to claim the throne before Robert returned.

Robert's troops landed at Portsmouth in 1101 to fight for the throne. Henry was awaiting him at Pevensey (coincidentally[?], near where their father had made his landing for the Norman Invasion of 1066), but caught up with Robert before he reached London, and defeated him. Henry convinced Robert to give up his claim to the throne for 3000 marks per year. That might have resolved their conflict—and it did, for a little while.

But then Ralph Flambard escaped from the Tower of London.

Robert Curthose

Yesterday's post mentioned Henry becoming king of England upon the death of his brother, William Rufus. Their father was William the Conqueror. William had more than two sons, however. In fact, neither Henry nor William Rufus was his eldest son.

His eldest was Robert Curthose (c.1051 - 3 February 1134). He might have eventually succeeded his father to the throne of England, but his own actions got in the way.

Robert had some admirable qualities, as noted by William of Malmesbury in his Gesta Regum Anglorum [Deeds of the Kings of England]:

...considered as a youth of excellent courage... of tried prowess, though of small stature and projecting belly... he was neither ill-made, nor deficient in eloquence, nor was he wanting in courage or resources of the mind. [Note the "small stature" line; the nickname, "curthose" likely derived from his legs being a little shorter than usual]

But he had a temper. In 1077—still a young man—his younger brothers were bored, and dumped the contents of a chamber pot on Robert from an upper gallery. The boys got into a fight, which their father had to break up. Enraged that his father did not punish the instigators, the very next day Robert tried to capture one of his father's castles, at Rouen. He failed, and fled ultimately to Flanders, where his mother secretly sent him money to support him. His mother, Matilda, arranged a reconciliation between father and son from that lasted from 1080 until her death in 1083, after which Robert left court and traveled Europe.

On William the Conqueror's death in 1087, he left England's throne to William Rufus, and £5000 silver to Henry. To his estranged and difficult eldest son, Robert, he left Normandy—a generous gift considering the troubles between them.

Robert continued to cause trouble for his siblings, however; a story for tomorrow.

Father of His Country

The phrase "Father of His Country" is usually reserved for George Washington, first President of the United States, for his role in the beginning of the system that the USA has today. But Henry I of England (1068 - 1135) was the father of his country in more than a symbolic sense.

As a son of William the Conqueror, his role was to continue the evolution of England to become a mixture of Saxon and Norman culture. When his brother, William Rufus, was killed in a hunting accident, Henry took the throne. He took as his queen Matilda of Scotland, with whom he had at least two children. A daughter, Matilda, was born in 1102 and lived until 1167. William Adelin, born in 1103, died in 1120 in the White Ship tragedy.

Matilda really wanted to be a nun, which may explain why she did not help to fulfill her "duties" to provide many heirs. After her death in 1118, Henry married a young wife named Adeliza of Louvain, with whom he had no children.

Henry had alternatives, however. By several different mistresses (some of whose names we know), he sired several "heirs":

• Robert Fitzroy ["son of the king"] (c.1100 - 1147), became the first Earl of Gloucester.
• Richard of Lincoln was raised in the household of the Bishop of Lincoln, Robert Bloet.
• Reginald de Dunstanville (c.1110 - 1175) was Earl of Cornwall and High Sheriff of Devon.
• Robert
• Gilbert
• William de Tracy
• Henry Fitzroy
• Fulk Fitzroy
• William de Dunstanville

...and that was just the boys. He had, by best estimate from references in historical documents, at least 15 daughters, including:

• Matilda Fitzroy, Countess of Perche (by becoming 2nd wife of Rotrou III, Count of Perche)
• Matilda Fitzroy, Duchess of Brittany (by marrying Conan III, Duke of Brittany)
• Matilda Fitzroy, Abbess of Montvilliers

How is that for a tribute to a first wife?

Saluzzo and England and Griselda

Saluzzo, a town and principality in northern Italy, had some interesting connections to England. It was a simple tribal city-state in Roman times, but during the time of the Carolingians it became the hereditary property of the Marquesses of Saluzzo, who extended their control over a wider region in the north. It was frequently in conflict with its powerful neighbor, the Duchy of Savoy, which eventually assumed much of Saluzzo's territory. The Savoys were so powerful that the kings of England and France treated them very well.

Griselda's daughter is carried away [source]

One of the first strategic marriages between English and Italian noble families, however, was with Saluzzo. Alice of Saluzzo (d.1292) married Richard Fitzalan, the 8th Earl of Arundel. The marriage had been arranged by Eleanor of Provence, Queen to Henry III. Alice's father, Thomas I of Saluzzo, was an exemplary ruler under whom Saluzzo flourished like never before. This probably had a lot to do with choosing to form an alliance with Saluzzo by marriage.

Not all Marquesses of Saluzzo came off so well in history—or literature.

In Geoffrey Chaucer's Canterbury Tales, The Clerk's Tale tells of Griselda, whose hand in marriage is sought by Marquess Walter of Saluzzo. He marries her on the condition that she will always obey him, no matter what. She agrees. When she gives birth to a daughter, Walter decides to test her obedience: he has a soldier remove her daughter. Although Griselda has every reason to believe her daughter is being killed (actually, the girl is sent to be raised by Walter's sister), she remains obedient and kind to her husband.

Four years later, she gives birth to a son. Walter chooses a further test: he tells her son has to go as well, that he has permission from the pope to divorce her, and that she is to return to her father taking nothing but the smock she wears under her fine dress. She returns home, showing no signs of distress.

Years later, Walter summons Griselda to him. He tells her he is marrying again, a young wife this time, and wants Griselda to help prepare the house for a new young bride. Unbeknownst to Griselda, the new young bride is actually her now-grown daughter. Griselda patiently asks Walter to be kind to his new bride, who might not be able to endure his tests the way a woman raised in poverty could. Walter, much moved by her patience and faithfulness, confesses that they are still married, that her children are alive, and promises never to test her again. They live happily ever after.

Chaucer did not invent this story. He probably got it from Boccaccio's Decameron, and the folktale of patient Griselda was around for a long time. Why the "villain" is a Marquess of Saluzzo is the mystery. But then, not all Marquesses were as beloved as Thomas I.  In Boccaccio's lifetime, Saluzzo experienced some civil strife. Manfred V of Saluzzo was forced to give up a claim to the throne in 1334 after being caught in a sex scandal with his own mother, then usurped the throne in 1341, but was forced to give it up a year later. 

Our Daily Bread

Bread has all the characteristics of a staple food: the plant is easy to grow, the product is relatively easy and cheap to produce, and it is adaptable to various shapes and uses. Human beings have been eating it for about 30,000 years, based on residue of starch found on tools used for pounding grain into meal.

The earliest breads were probably flatbreads, before rising or leavening agents were discovered. Some leavening would take place naturally, by airborne yeasts landing on dough left out. Pliny the Elder reported that Gauls and Iberians added the foam from beer to make bread that was lighter in texture.

The earliest known Arabic cookbook, The Book of Dishes, by Ibn Sayyar al-Warraq (10th century), explains:

Wheat bread agrees with almost everybody, particular varieties made with a generous amount of yeast and salt and allowed to fully ferment and bake well. Such breads are lighter and digest faster. Jizmazaj (thin bread with tamarisk seeds) and ruqaq (very thin bread) are by comparison less nourishing and digest much faster. Bread baked in malla (pit with hot ashes and stones), tabaq (large flat pan) and any other similar varieties that do not ferment or bake well are hard to digest and cause stomach aches. Only people used to strenuous labor can eat them more often.

Bread was considered so important to people and the economy that it was heavily regulated. The Assize of Bread and Ale during the reign of Henry III (1207 - 1272) determined "proper" weight and price and quality of bread.

Bread was such an important part of daily life that the name for someone with whom you spend a lot of time, companion, comes from the Old French compaignon, "one with whom one shares bread" (from Latin com="with" and panis="bread").

Outnumbered!

Memorial to Battle of Näfels

Military engagements between England and France were a large part of the 14th century in Europe, but those countries were far from the only two engaged in war. Much of the 14th century saw conflicts between Austria and the Swiss. The final engagement of that war was the Battle of Näfels in 1388.

The opponents were Glarus (one of the Cantons of Switzerland) and the Old Swiss Confederation against the Hapsburgs of Austria. In 1386, the Old Swiss Confederation besieged the Hapsburg village of Weesen. In 1387, Glarus rose up against its Austrian occupiers and declared itself free of Hapsburg control.

In retaliation, the Austrian army, in February 1388, drove the Swiss out of Weesen. In April, the Austrian army decided to attack Glarus; 5000 men marched toward Näfels, a municipality in Glarus; on the way, they were joined by a column of 1500.

Näfels had for its defense about 400 men. Outnumbered 16 to 1, after a brief resistance the men of Näfels scattered, disappearing off the fortifications and into the snow- and fog-filled night. The Austrians, emboldened, broke ranks and began to pillage the outlying farms.

But the Glarners had counted on that. They began appearing out of the fog and snow, picking off the Austrian soldiers in ones and twos. A quick attempt to pull together the ranks resulted in a brief battle, but the now disoriented and slightly demoralized Austrians decided to retreat, despite their overwhelming numbers. In crossing the Linth River, a collapsing bridge dropped many Austrians into the river to drown. Ultimate losses for the Austrians are difficult to estimate, but some say up to one-third of the army was killed over the course of a couple of days. A monument exists to honor the (only) 54 Swiss Confederation and Glarner men who were killed.

Aprille

It is the first of April, and while you might expect something about pulling pranks and acting the fool, instead we are going to talk about...April. Chaucer's most famous poem starts with a mention of April and its sweet showers, but did he know what "April" meant?

April lovers from the Margaret de Foix Book of Hours

We are not sure why it is called April, from the Latin Aprilis. The Greeks call this month άνοιξη [ánoixé], which means "opening." This is because April is traditionally when the earth starts to renew itself and flowers and buds begin to open. Based on this, April might come from Latin aperture, "to open," from which we get words like aperture.

On the other hand, since the Romans liked to name their months for practical reasons, either after gods (January) or Caesars (July and August) or simply numerically (September, October, etc.), maybe we should see if April fits the pattern. Perhaps Aprilis was actually Aphrilis, as in Aphrodite, the Greek name of Venus. After all, Venus had a festival, the Veneralia, held on 1 April, in honor of Venus Verticordia ["Venus the Changer of Hearts"].

Maybe the Middle Ages knew of this origin, since illustrated calendars and books of hours often had pairs of lovers to represent April, as we see above. (To be honest, this was a later medieval trend; earlier, April just had someone holding a green branch to show life coming back to Nature.)

The Anglo-Saxons called it ēastre-monaþ; we don't know why. Bede tells us that it was named for a goddess, Eostre, and that this is why the Anglo-Saxons called the Resurrection "Easter." Einhard says the same, but he probably got it from Bede.

Hug a Medievalist

This is worth knowing.

A bear hunter hugging a bear?
Early 16th c. German "Geese Book"

Sarah Laseke, writer of a medieval blog here, in 2011 decided that if librarians get a "Hug a Librarian" Day, then medievalists should get a "Hug a Medievalist" Day. She started with a Facebook page, from which the idea gained widespread interest.

Folk in the Middle Ages knew about hugging, although it does not seem likely that it was a very public gesture. As one website puts it:

The nobility ... had plenty of space and did not press closely on each other. Gentlemen and ladies allowed a lot of personal space to each other. Hugging and hanging on each other was simply not done in public, especially not by ladies in a broad-spreading double-horned headdress, except with great care. Getting close enough for a kiss required a lady's co-operation... [link]

In the 21st century, however, we do not have the same taboos about personal space—or the clothing that prohibits closeness. Feel free to find and hug a Medievalist today, and we will return to more scholarly (and less self-serving) topics tomorrow.

The Seventh Crusade

King Louis IX of France could not convince any of the rulers of Europe to accompany him on a Crusade to free Jerusalem, which had been recaptured in 1240. He organized and funded (by taxing the church) the Seventh Crusade himself. It could have gone better.

Battle of Mansura

After wintering in Cyprus, he took the town of Damietta in Egypt to use as a base, then had to sit there for six months while the Nile flooded, which gave his enemies time to assemble their forces. Marching toward Cairo, he was stopped by a canal near Mansura, on the other side of which was an Egyptian army larger than his.

Louis tried building a causeway across the canal, but the Egyptians simply dug away at their side of the canal, widening it and putting their bank every farther out of his reach. After two fruitless months, he sent his cavalry to cross at a shallow ford 4 miles upstream. Louis' brother Robert was to hold the cavalry until a signal, but he charged into Mansura, probably seeking his own glory, and succeeded in wiping out most of the cavalry. The Crusaders were too weak to take and hold Mansura, and so Louis retreated to Damietta.

On 6 April, 1250, at the Battle of Fariskur, the Egyptian Mamluks defeated the Crusaders and captured Louis. His ransom was 800,000 gold livre and the return of Damietta to the Egyptians. Louis sailed to Acre in Syria, where he tried to get help to continue the Crusade. He negotiated with the Mongol Möngke Khan through his emissary, William of Rubruck, which infuriated the Mamluks, whose territory to the east had been invaded by the ever-spreading Mongols.

By 1254, Louis had run out of money and, word coming that his mother, Blanche of Castile, who had been running France in his absence, had died, he had to return to France. Louis would try another Crusade, the Eighth, in 1270, where he would die on 25 August in Africa from "a flux in the stomach." He should have simply stayed home.

The Crusade Nobody Wanted

In 1244, allies of the Egyptian Mamluks, retreating westward from the advancing Mongols, stopped at Jerusalem long enough to recapture it from European Christian control. Jerusalem had come under Christian control during the Sixth Crusade under Holy Roman Emperor Frederick II in 1228.

King/Saint Louis sailing on the Seventh Crusade

King Louis IX of France, whose devotion was so great that he became Saint Louis, immediately began planning an action to return Jerusalem to Christian control. He sent word throughout Europe to join him in a Seventh Crusade.

Europe's response to this calamity was not what one would expect. The truth is, Europe was pretty busy with its own problems. The Pope, Innocent IV, who under usual circumstances would have been the one to call a Crusade, was locked in a political struggle with Frederick II over the question of which of them controlled the Holy Roman Empire. Henry III of England was dealing with Simon de Montfort's rebellion. (Henry did agree not to attack France while Louis was away.)

Louis appealed to Hungary, but King Béla IV was rebuilding after a Mongol invasion. Louis even appealed to King Haakon IV of Norway. Haakon was interested in making deeper European ties, and had made a vow of Crusade once, but then converted it to a vow to fight against pagans in the north (Mongols had started coming north). Louis sent Matthew Paris to offer Haakon command of the French fleet, but Haakon refused.

The only person in Europe who was keen for this Crusade was Louis himself, but as a "one man show" he was very well organized. He commissioned ships to be built specifically for transporting his men and horses and supplies, and raised money by collecting a tithe (tenth) from churches. He sailed to Cyprus for the winter, negotiating with other forces (such as the Knights Templar) for mutual help. He then went to Egypt, where he took the town of Damietta to use as a base. Then the annual flooding of the Nile took place, and he was grounded for six months.

From there it went downhill.

The Saint Who Said "No"

Saint Isabella, at a
church in Paris

Isabella of France (1224 - 1270) was the daughter of King Louis VIII and Blanche of Castile. Her brothers became King Louis IX of France, Count Alfonso of Poitiers, and King Charles I of Sicily. Her royal upbringing included not only the typical feminine arts like embroidery, but also study of Latin and literature, such as romances and religious works.

She became attracted to the mission of the Franciscans, and by special dispensation of Pope Innocent IV, she was allowed to have Franciscans as her confessors, rather than regular priests. She was very devout, and took special interest in applying her embroidery skills on priestly vestments. Once, while making a nightcap, her brother the king asked for it. She said "No. This is the first of its kind and I must make it for my Savior Jesus Christ.” She finished the nightcap, gave it to a poor person, and made her brother another,

As devout as she was, however, she was still a royal princess, with obligations beyond what most daughters experience. She was betrothed to marry Hugh, the future Count of Angoulême and of La Marche. Isabella was determined to remain a virgin, and so said "No" and would not carry through on the wedding plans. Unable to secure an heir, Hugh looked elsewhere. (This did not cause harm to the relation between the two families: Hugh later joined Isabella's brother Alfonso on the Seventh Crusade, where he was killed in Egypt.)

Later, she was betrothed to Conrad IV of Germany, son of Holy Roman Emperor Frederick II. Politically, this match would have been more impressive than the one with Hugh, and everyone thought it a good idea, even Pope Innocent IV, who entreated her to agree to it. But Isabella said "No" again. She explained to the pope that she wished to live a religious life, though not entering a religious order, and part of that involved remaining a virgin.

Isabella asked to be able to found a monastery of Poor Clares (Clare was the sister of Francis of Assisi). Sanction from Pope Alexander IV dated 2 February 1259 shows that the Monastery of the Humility of the Blessed Virgin was completed by that date. Isabella lived in the monastery, but apart from the nuns' cells. Offered the position of abbess, she again said "No": if she were abbess, she would have to give up the riches available to a royal princess, and would not be able to support the monastery.

After her death and burial, her body was exhumed after nine days and observed to be uncorrupted. That, and the reports of miracles happening at her grave, caused her to be declared a saint. Her feast day is 23 February.

The Name Glastonbury

Glastonbury is a small town in Somerset, England, that has been inhabited since Neolithic times. A recent post discussed the discovery of early medieval glass-making furnaces at the site of the now ruined Glastonbury Abbey. This prompted some to point out to me that Glastonbury "must have been known" for glass production—it is "right there in the name." Let us address that.

Remains of the nave of Glastonbury Abbey

In his book The Flowering Hawthorn, Hugh Ross Williamson tells the story of St. Collen. Collen was a 7th century hermit who took up residence at what is now Glastonbury. Williamson relates how the saint encountered Gwyn, King of the Fairies, in a magical glass castle on Glastonbury Tor. Rejecting the fairies' offer of food and drink, he cast holy water on them, causing all to vanish. Numerous versions of this story exist, but Williamson's 1962 book is the only version that introduces glass as the material involved. As a source for the site's name, this is not reliable.

William of Malmesbury refers to its earliest name as Ynys Witrin, which some translate as "Isle of Glass" based on the fact that English "vitreous" comes from Latin "vitrum" meaning "glass." "Isle of Glass" would more properly be Ynys Gwydr, however. "Witrin" is a puzzle, but no serious scholar thinks it is from Latin for "glass." (The "Isle" makes sense because, in earlier times, higher sea levels turned some hilly areas into islands.) Malmesbury does suggest that the place was named for someone named Glast. Since the first recording of the name is Glestingaburg, the place of Glestinga. No one knows exactly to what Glestinga refers.

But it's not about glass.
