Trinity Chapel

Trinity Chapel is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Trinity Chapel rather than just read about it. In short: Trinity Chapel at the east end of Canterbury Cathedral forms part of a UNESCO World Heritage Site. It was built under the supervision of the master-masons William of Sens and William the Englishman as a shrine for the relics of the martyred Archbishop of Canterbury Thomas Becket.

Reference excerpt

Trinity Chapel at the east end of Canterbury Cathedral forms part of a UNESCO World Heritage Site. It was built under the supervision of the master-masons William of Sens and William the Englishman as a shrine for the relics of the martyred Archbishop of Canterbury Thomas Becket. The shrine became one of the most popular pilgrimage sites in England.

Origin The chapel was constructed between 1179 and 1184, replacing a much smaller chapel of the same name destroyed by fire, along with much of the rest of the choir, in 1174. Its predecessor was where Becket celebrated his first mass following his installation as Archbishop of Canterbury.

Thomas Becket In 1220, Becket's remains were translated from his first tomb to the finished chapel. As a result of this event, the chapel became a major pilgrimage site, inspiring Geoffrey Chaucer to write The Canterbury Tales in 1387 and with routes (e.g. from Southwark (Chaucer's route) and the Pilgrim's Way to/from Winchester) converging on the cathedral. Becket's shrine stood until it was destroyed in 1540. This was done on orders from King Henry VIII as vengeance for his ancestor, Henry II. The king also destroyed Becket's bones and ordered that all mention of his name be obliterated. The pavement where the shrine stood in the chapel is today marked by a lighted candle. Modern day archbishops of Canterbury celebrate the Eucharist at this place to commemorate Becket's martyrdom and the translation of his body from his first burial place to this chapel.

The Black Prince Over time other significant burials took place in this area such as Edward Plantagenet (the Black Prince), who was interred on the south side of Becket's shrine. His tomb consists of a superb gilded copper effigy beneath a tester depicting the Holy Trinity, with his heraldic achievements hung over the tester. The achievements have now been replaced by replicas, though the originals can still be seen nearby, and the tester was restored in 2006.

King Henry IV Also buried in the chapel are King Henry IV and his second wife, Joan of Navarre, Queen of England. Henry's tomb is on the north side of Trinity Chapel, next to the shrine of St Thomas Becket. It was unusual for a King of England not to be buried at Westminster Abbey, but Becket's cult was then at its height, as evidenced in the Canterbury Tales, and Henry seemed particularly devoted to it, or at least keen to be associated with it. Reasons for his interment in Canterbury are debatable, but it is highly likely that Henry deliberately associated himself with the martyred saint for reasons of political expediency, namely, the legitimation of his dynasty after seizing the throne from his cousin, Richard II. Significantly, at his coronation, he was anointed with holy oil which was said to have been given to Becket by the Virgin Mary shortly before his death in 1170; this oil was placed inside a distinct eagle-shaped container of gold. According to one version of the legend, the oil had then passed to Henry's maternal grandfather, Henry of Grosmont, 1st Duke of Lancaster. Evidence of Henry's deliberate connexion to St Thomas lies in the structure of the tomb itself. The wooden panel at the western end of his tomb bears a painting of the martyrdom of Becket, and the tester, or wooden canopy, above the tomb is painted with Henry's personal motto, 'Soverayne', alternated by crowned golden eagles. Likewise, the three large coats of arms that dominate the tester painting are surrounded by collars of SS, a golden eagle enclosed in each tiret. The presence of such eagle motifs most likely points directly to Henry's coronation oil and his ideological association with St Thomas. Sometime after the King's death, an imposing tomb was built for him and his queen, probably commissioned and paid for by Queen Joan herself. On top of the tomb chest lie detailed alabaster effigies of the King and Queen, crowned and dressed in their ceremonial robes. Henry's body was evidently well-embalmed, as an exhumation in 1832 established, allowing historians to state with reasonable certainty that the effigies are accurate portrait.

The Corona Tower The Corona Tower (sometimes known as "Beckets's Crown"), a circular structure at the east end of the Trinity chapel, is widely thought to have received its name from having been built to contain the relic of the crown of St Thomas's head which was struck off during his murder. However, Robert Willis in his Architectural History of Canterbury Cathedral (1845) rejected this idea, saying that 'corona' was a word applied to the eastern apses of many churches in the medieval period. In his account of a visit to the cathedral, before the destruction of the shrine, Erasmus said that the saint's head was displayed in the crypt. Records of valuable gifts made there by pilgrims in the 13th century do, however, indicate that there were some relics of St Thomas Becket in the Corona. The shrines of St Odo and St Wilfred were also eventually placed there.

Worked examples

Example 1 — a first encounter with Trinity Chapel

Start with the simplest possible case. Write down what Trinity Chapel claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Trinity Chapel before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Trinity Chapel ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Trinity Chapel

In research: Trinity Chapel appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Trinity Chapel in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Trinity Chapel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 12th-century church buildings in England, Buildings and structures completed in 1184, Buildings and structures in Canterbury, so understanding it makes those chapters shorter.
In everyday life: Look for Trinity Chapel outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
