York Minster

York was founded in 71 CE as Eboracum, a Roman fortress overseeing the north of Britain. We know that York had a Christian community by 314, because a "bishop of York" was part of the Council of Arles that year. York's Christian history is not well-documented in the early centuries, however. The first church we have records of was built on the spur of the moment in 627 to baptize King Edwin of Northumbria; it was wooden, and didn't last, but Saint Wilfrid rebuilt it in stone, and by the 8th century the school and library were thriving.

That church was destroyed in a fire in 741. Bishop Egbert started the rebuilding, resulting in what Alcuin in his letters described as:

very tall, and held by solid columns which support curved arches; beautiful panels and numerous windows make it shine with brilliance. Its magnificence is increased by its gantries, terraces and thirty altars, decorated with a rare variety.

It was damaged by William the Conqueror in 1069, but then his Norman Archbishop Thomas of Bayeaux in 1070 started rebuilding. It was damaged again in 1075 by Danes, but in 1080 the repairs started. This new large (364 feet long) building was damaged by fire in 1137. The pattern of damage (by fire or attack) and repair has continued, right up to a fire in 1984 when 110 firefighters deliberately dumped enough water on the south transept to crash the roof completely, smothering the blaze and preserving the rest of the minster. Despite these events, York still has some of the oldest stained glass in England.

In 1215, a Gothic church was started, to replace the Norman architecture. Archbishop Walter de Gray also wanted its magnificence to rival Canterbury, since the Archbishops of York resented that the Archbishops of Canterbury were considered to have authority over all England's churches.

The term "minster" is from the Anglo-Saxon period, and denotes a church for teaching missionaries. That is no longer the purpose of York, but the honorific has stuck.

Despite the stone construction of many churches, they could still contain flammable material: carvings, roof beams, furniture, tapestries, etc. Churches in the Middle Ages could also contain flammable material that we never see or think of these days. Tomorrow I want to talk about the medieval event called "rushbearing."

York Library

York was an early center of Christianity in Britain, and had its own bishop from at least the 4th century. In 735, Ecgbert of York became its bishop; he is credited with beginning the school and library at the York Minster.

The collection of works there is estimated to be about 100 items—a remarkable number for the time. A poem by Alcuin mentions 40 different titles, including not only works by Bede and the Church Fathers but also by such classical authors as Aristotle, Cicero, and Pliny.

Alcuin's extant letters tell us that he made trips to procure books for the library, and that he brought some with him when he left York to take up his position at Charlemagne's court at Aachen. Despite his new patron's desire to promote learning, however, Alcuin makes clear that he never created a better library than the one in York.

Some of the books were given to Liudger the Frisian, called the "Apostle of Saxony," when he left studying at York to preach on the continent. Liudger founded a monastery at Werden. The monastery is gone, and some buildings are being used by a school, but it is possible that some fragments of York books still exist in southern Germany.

The Alcuin-era library is no more. Danes sacked the area in 866, and it suffered further at the Harrowing of the North by William the Conqueror.

The York Minster library was formally re-founded when John Neuton (c.1350 - 1414), a canon at York, left a bequest of about 70 books to the Minster. (The illustration above is an initial page of a law text that had been part of his collection.) Few of those original books survive, but York Minster has had a library for over 600 years, thanks to Neuton.

Next I'd like to talk about the Minster itself, and why it's called that instead of Cathedral. Stay tuned.

Glass and Recycling

In 1977-79, a shipwreck off the southern coast of Turkey was investigated. It was determined to have sunk about 1025. The ship's hold contained three tons of broken glass and chunks of glass. (This amount of glass would make about 12,000 Coke bottles.)

Glass requires extreme heat applied to a mixture of silica, soda, and lime. Silica was derived from sand; soda happens to reduce the temperature at which glass can form; lime makes the glass "chemically stable." Impurities—by accident or design—added color to the glass.

We know little about how glass-making came about; records do not explain the technique, but anecdotal mentions tell us a little. Pliny's Natural History tells us that the best sand for glass comes from the mouth of the Belus River near Akko, Israel. The shells in that sand provide the lime needed to make the glass stable. William of Tyre (1130-1186) and Jacques de Vitry (1170-1240) around 1200 both mention the same source. It is thought that the ancients did not understand why that source was the best, chemically, that they did not understand that the shells contained necessary lime.

In England, the Glastonbury Abbey Project has discovered evidence of a stone structure on the site of Glastonbury Abbey dating to c.700. They have also found evidence of early Roman and Saxon activity from before the Abbey's founding. Remains of glass-making furnaces have been uncovered, showing archaeologists that Saxons were recycling Roman glass brought from Europe. The Glastonbury site was possibly the first Saxon glass-making factory in England.

The remarkable thing about glass is that it is recyclable, like metals. Although it took a lot of energy to process, every bit of broken material (unlike wood or stone or pottery) could be re-smelted and re-cast. It is possible that the glass in windows like the example above was even older than our estimates, having been re-used from earlier glass objects that broke or had outlived their usefulness.
