Saint-Sulpice (Paris)
Encyclopedia
Saint-Sulpice is a Roman Catholic church in Paris
, France
, on the east side of the Place Saint-Sulpice
, in the Luxembourg Quarter of the VIe arrondissement
. At 113 metres long, 58 metres in width and 34 metres tall, it is only slightly smaller than Notre-Dame
and thus the second largest church in the city. It is dedicated to Sulpitius the Pious
. During the 18th century, an elaborate gnomon
, the Gnomon of Saint-Sulpice
, was constructed in the church.
church originally constructed during the 13th century. Additions were made over the centuries, up to 1631. The new building was founded in 1646 by parish priest Jean-Jacques Olier
(1608–1657) who had established the Society of Saint-Sulpice
, a clerical congregation
, and a seminary attached to the church.
Work continued for about 140 years: The church was mostly completed in 1732; the chancel is the work of Christophe Gamard, Louis Le Vau
and Daniel Gittard, but the work was completed by Gilles-Marie Oppenord, a student of François Mansart
, in 1714-1745.
The façade is an unorthodox essay of 1732 by Giovanni Niccolò Servandoni
in which a double Ionic colonnade, Ionic order
over Roman Doric
with loggia
s behind them unify the bases of the corner towers with the façade; this fully classicising statement was made at the height of the Rococo
. Its revolutionary character was recognised two decades later by the architect and teacher Jacques-François Blondel
, who illustrated the elevation of the façade in his Architecture française, remarking, "The entire merit of this building lies in the architecture itself... and its greatness of scale, which opens a practically new road for our French architects." It has been modified by Jean Chalgrin
and others. Large arched windows fill the vast interior with natural light. The result is a simple two-storey west front with three tiers of elegant columns. The overall harmony of the building is, some say, only marred by the mismatched two towers; one, to the neoclassical
design of Jean François Chalgrin
, was added shortly before the French Revolution
but its matching tower was never begun, and the former tower remains.
At either side of the front door are two enormous shells given to King Francis I
by the Venetian Republic. The two shells rest on rock-like bases, sculpted by Jean-Baptiste Pigalle
.
Nineteenth-century redecorations to the interior, after some Revolutionary damage when Saint-Sulpice became a Temple of Victory, include the murals of Eugène Delacroix
, that adorn the walls of the side chapel. The most famous of these are Jacob Wrestling with the Angel
and Heliodorus Driven from the Temple. Jules Massenet
set an act of Manon
at fashionable Saint-Sulpice.
Another point of interest dating from the time of Saint-Sulpice serving as a Temple of Victory is a printed sign over the center door of the main entrance. One can still barely make out the printed words ‘’Le Peuple Francais Reconnoit L’Etre Suprême Et L’Immortalité de L’Âme’’, The people of France recognize the supreme being and the immortality of the soul. Further questions of interest are the fate of the frieze that this must have replaced, the persons responsible for placing this manifesto and the reasons that it has been left in place.
The Marquis de Sade
and Charles Baudelaire
were baptized in Saint-Sulpice (1740 and 1821, respectively), and the church also saw the marriage of Victor Hugo
to Adèle Foucher (1822). Louise Élisabeth de Bourbon and Louise Élisabeth d'Orléans, grand daughters of Louis XIV and Madame de Montespan are buried in the church. Louise de Lorraine
, duchesse de Bouillon was buried here in 1788, wife of Charles Godefroy de La Tour d'Auvergne
.
reconstructed and improved the existing organ
built by François-Henri Clicquot
. The case was designed by Jean-François-Thérèse Chalgrin and built by Monsieur Joudot.
Though using many materials from Clicquot's French Classical organ, it is considered to be Cavaillé-Coll's magnum opus, featuring 102 speaking stops, and is perhaps the most impressive instrument of the romantic French symphonic-organ era.
Its organists have also been renowned, starting with Nicolas Séjan in the 18th century, and continuing with Charles-Marie Widor
(organist 1870-1933) and Marcel Dupré
(organist 1934-1971), both great organists and composers of organ music. Thus for over a century (1870–1971), Saint-Sulpice employed only two organists, and much credit is due to these two individuals for preserving the instrument and protecting it from the ravages of changes in taste and fashion which resulted in the destruction of many of Cavaillé-Coll's other masterpieces. The current organists are titulaire Daniel Roth
(since 1985) and assistant titulaire Sophie-Véronique Cauchefer-Choplin.
This impressive instrument is perhaps the summit of Cavaillé-Coll's craftmanship and genius. The sound and musical effects achieved in this instrument are almost unparalleled. Widor's compositional efforts for the organ were intended to produce orchestral and symphonic timbres, reaching the limits of the instrument's range. Albert Schweitzer, his student and collaborator-- despite initiating an "Orgelbewegung," or organ reform movement, which deplored many nineteenth-century developments-- called this organ the most beautiful in the world. More recently, Stephen Bicknell concurred, pointing out that the full ensemble of many large organs is dominated by a few powerful stops; but at S. Sulpice many ranks, each of moderate power, contribute to a sound of dazzling complexity. With five manuals— keyboards— and boasting two 32-foot stops, organists at St. Sulpice have an incredibly rich palette of sounds at their disposal.
Aside from a re-arrangement of the manual keyboards c. 1900, the installation of an electric blower and the addition of two Pedal stops upon Widor's retirement in 1934 (Principal 16' and Principal 8' donated by Societe Cavaille-Coll), the organ is maintained today almost exactly as Cavaillé-Coll left it.
In Saint-Sulpice sunday organ recitals are held on a regular basis (Auditions du Dimanche, following the High Mass, usually from 11:30 till 12:05 clock, during the subsequent mas, a visit of the organ loft possible).
"Built by Daublaine and Callinet in 1844, the Choir organ of St. Sulpice was restored and enlarged by Cavaillé-Coll in 1857 to provide the church with a strong instrument capable of accompanying the large ceremonies of the Seminary. It was again restored in 1903 by Mutin and has been preserved in that condition to the present day." - JAV Recordings
This organ allowed C.M. Widor to compose his Mass for two organs and two choirs. Combining the Great Organ with the Choir Organ, he created a beautiful example of antiphony.
, then priest of Saint-Sulpice, requested the construction of a gnomon
in the church as part of its new construction, to help him determine the time of the equinoxes and hence of Easter
. A meridian line of brass was inlaid across the floor and ascending a white marble obelisk, nearly eleven metres high, at the top of which is a sphere surmounted by a cross. The obelisk is dated 1743.
In the south transept window a small opening with a lens was set up, so that a ray of sunlight shines onto the brass line. At noon on the winter solstice (21 December), the ray of light touches the brass line on the obelisk. At noon on the equinoxes (21 March and 21 September), the ray touches an oval plate of copper in the floor near the altar.
Constructed by the English clock-maker and astronomer Henry Sully
, the gnomon was also used for various scientific measurements: This rational use may have protected Saint-Sulpice from being destroyed during the French Revolution
