Reference excerpt

The Église Saint-Leu-Saint-Gilles de Paris is a Roman Catholic parish church in the 1st arrondissement of Paris. It has housed the relics of the Empress Saint Helena, mother of Constantine, since 1819, for which it remains a site of veneration in the Roman Catholic and Eastern Orthodox churches. In 1915 the French Ministry of Culture listed it as a monument of historical value.

History

In the 12th century, a small chapel dedicated to Saint Gilles, a hermit or monk in the Rhone Valley in the 6th century, occupied the site, within the Monastery of Saint-Maggiore, and close to the royal road that led from Paris to the Basilica of Saint-Denis. In 1235 construction began of a new church independent of the monastery, dedicated to Saint Gilles and later also to Saint Lupus of Troyes, or Saint Leu, who was credited at the time with saving Troyes from an attack by Atilla the Hun. As the population of the neighborhood grew, the church was rebuilt in 1319, and underwent several major renovations and modifications, notably in 1611, 1727, and 1780, when an underground chapel was added. It was closed and badly damaged during the French Revolution, when it was turned into a storehouse for food. It was returned to the church in 1802 under Napoleon Bonaparte. The Boulevard de Sébastopol was constructed behind the church by then-President and future Emperor Napoleon III, resulting in the demolition of three chapels and the apse. A renovation was carried out by architects Étienne-Hippolyte Godde and Victor Baltard. The church was closed and damaged again during the Paris Commune in 1871, but was restored.

The Knights of the Holy Sepulchre and the reliquary of Saint Helena In 1780 the Knights of the Order of the Holy Sepulchre, a religious order which had originally been created in 1099 during the Crusades to protect early Christian sites in the Holy Land, established their headquarters in the church. They particularly venerated Saint Helena, the mother of the Emperor Constantine and an important figure in the early history of Christianity. In 1819 the relics of Saint Helena had been transferred to the church from the Abbaye Saint-Pierre d’Hautvillers by the Knights. In 1875, the reliquary of Saint Lupus of Sens was opened in order to carry out an anatomical analysis of the remains of Saint Helena. Based on the medical findings, Monsignor Richard, Archbishop of Paris, announced that the “reliquary contained the almost-complete torso of Saint Helena”, that “the head was missing and the limbs compressed”, and that “the state of the body conserved in the reliquary of the Église Saint-Leu-Saint-Gilles corresponded to the descriptions known to the Bollandistes in the 18th century”. The reliquary was subsequently placed on open display above and behind the high altar, at the feet of the large crucifix, suspended between two pillars of the apse. The Knights of the Holy Sepulchre moved their headquarters from the church in 1830, but on 16 October 1928, Cardinal Dubois, Archbishop of Paris, held a ceremony in the church for the “Reintegration of the Knights of the Holy Sepulchre”. The building was subsequently made chapter house of that order. The order undertook a new mission to assist the Christian community in the Holy Land. On 17 March 2000 the relics of Saint Helena were transferred to the crypt of the order's knights, making them more easily accessible for veneration. The first Eastern Orthodox liturgy was celebrated before the relics of Saint Helena on 22 February 2003. The church is now managed by the Trinitarian Order. It pays particular attention to the homeless of its neighborhood, Les Halles.

Exterior

The facade on Rue Saint-Denis is distinguished by two high towers, but the rest of the exterior is difficult to see because of the narrow streets. The outer aisles of the nave and choir were added later, and probably replaced earlier external buttresses. The apse of the church was considerably shortened in the 19th century and three chapels were removed to make space for the new boulevard built by Napoleon III.

Interior

The church is built in the Gothic style of the 14th century. This was a period of economic hardship, political conflict, and an outbreak of the black death, or plague in Paris. As a consequence the interior of the church was more austere than earlier or later Gothic churches in Paris.The church's single nave counts numerous stained-glass windows. It is flanked by aisles, but the church has no transept. pl The church did not originally have collateral aisles and chapels, which were added in the 16th century. It most likely had external buttresses placed where the collateral aisles are today. The four-part Gothic rib vaults over the nave transfer the weight of the roof downward and outwards to rows of columns, which form arcades with pointed arches. The present choir, the area of the church where the clergy worship, was constructed in 1611 after a large crypt was built underneath the church. The choir in the Renaissance style, blended with rib vaults and other Gothic elements.

Worked examples

Example 1 — a first encounter with Saint-Leu-Saint-Gilles de Paris

Start with the simplest possible case. Write down what Saint-Leu-Saint-Gilles de Paris 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 Saint-Leu-Saint-Gilles de Paris 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 Saint-Leu-Saint-Gilles de Paris 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 Saint-Leu-Saint-Gilles de Paris

In research: Saint-Leu-Saint-Gilles de Paris 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 Saint-Leu-Saint-Gilles de Paris 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: Saint-Leu-Saint-Gilles de Paris is common in secondary-school and first-year university syllabi. It links to neighbouring topics 13th-century Roman Catholic church buildings in France, Buildings and structures completed in 1235, Churches completed in the 1230s, so understanding it makes those chapters shorter.
In everyday life: Look for Saint-Leu-Saint-Gilles de Paris 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.
