Fragments of architecture

Fragments of architecture

Far from being fixed in time and space, architecture combines several goals which go, as Vitruvius reminded us in his "De architectura" in the first century BC, from the search for solidity to convenience and beauty. Today, we could probably add to this the will to establish constructions capable of ensuring the conservation and transmission of past productions. This exhibition proposes to approach this vast subject through four sections:
The materials and tools of construction:
The techniques of decoration
The functionalities of the building
The funerary architecture and memory

BUILDING MATERIALS

BUILDING MATERIALS

In architecture, the choice of building materials is governed by many parameters. The economy of means in construction may motivate a supply of proximity, as well as the search for raw materials that are easy to obtain, such as earth, wood and plant fibers.

Inversely, a prestigious work may justify the use of noble materials, such as stone, metal or glass. In this case, their extraction, transportation or implementation costs are an integral part of the architectural project.

The archaeology of the built environment allows us to document the different phases of the construction site, as well as the materials and techniques used.

Revêtement de sol

2nd Iron Age [- 480/ - 50]

small molded bricks, Late 1st century BC - early 1st century AD

archaeological context

Earth, in both its raw and fired forms, is an almost inexhaustible raw material. It is easy to extract and economical to work with. It is an excellent thermal insulator and has good pressure resistance capabilities. Unlike stone paving - which is mostly used in high-traffic areas (roads, public spaces) - earthen floors allowed for both economical installation, decorative treatment, as well as effective surface sealing. However, due to greater wear and tear and fragility, paving bricks were more generally laid edge-on following a herringbone pattern to ensure proper wedging.

Tuiles plates

Modern period [1492 / 1789]

Vegetable Fiber (thatch or reed) was one of the earliest coverings used in gable roofing. The adoption of tiles in roofing was most likely motivated by the need to limit fires because of their fireproof properties. Archaeology has been able to document the use of clay, baked or glazed tiles, wood, slate, as well as stone or metal. The tiles are generally laid lengthwise and superimposed in the direction of the slope, although they can be matched to produce various geometric patterns. Most often nailed or hooked - as we can see in this example from the city of Nancy - in the case of steeply sloped roofs, they can also be fastened with screws.

Pic

Gallo-Roman [- 50 / 476]

Iron carrier peak

archaeological context

Stone is one of the most frequently used building materials since ancient times, and this is because of its structural role and ornamental use. The exploitation of the stone begins "in quarry". The blocks were cut as close as possible to their final shape in order to lighten their weight and thus reduce the cost of their transport. The tools of the stonemason show a strong continuity from the Roman period to the XXth century. Corners, picks and saws were used in the extraction. Once the block was squared, the compass, the ruler and the square were used to trace the contours of the cut. The finishing touches were then made with punches, chisels or gradines. All of these instruments leave characteristic imprints on the stone that guide the archaeologist in the identification of the tools.

Game or model piece

Game or model piece

Scale models representing typical buildings, especially dwellings, have been attested since the Neolithic period in the Mediterranean basin. Whether they are made of wood, wax, stone or clay, their use remains uncertain. Often discovered in a funerary context, other examples have been associated with liturgical uses (offerings), domestic uses (games), or with real construction projects. The use of architectural models - difficult to confirm from material evidence - is described in classical texts. They are mentioned in the organization of competitions for the construction of prestigious buildings, such as the one for the refurbishment of the council hall of Kymè of Aeolian in the 2nd century CE.

The setting

The setting

If the construction of a building is often associated with its decoration, very few examples reach us during archaeological excavations. The solidity of certain elements, from ancient mosaics to modern concrete, gives us an idea of the atmosphere that reigned in these structures, but the wall paintings are most often destroyed because of their fragility, while some elements are replaced and modified over time. Exceptional discoveries sometimes illustrate a past decorative program, but most often it is a matter for the archaeologist to reconstruct according to known models.

Mosaïque de Penthée

Early Imperial [27 / 235]

This mosaic, discovered during excavations carried out in Nîmes in 2007, adorned the floor of a sumptuous Roman house (domus). It was executed using the Roman technique of opus tesselatum. On a first layer of pebbles (statumen) is poured a layer of aggregate of lime, gravel and stone (rudus), then a mortar of lime and debris of terra cotta (nucleus). Finally, on a thin layer of mortar, the decoration made of tesserae of 3 to 5 mm on a side is laid and fixed with a milk of lime.

Peinture murale d'un philosophe et d'une architecture

Gallo-Roman [- 50 / 476]

Discovered at the foot of Strasbourg's cathedral in 2012, during excavations of the Argentorate camp, this fresco adorned one of the houses of the six tribunes commanding the Roman legion. The fresco is a pictorial technique that assumes a certain skill and speed of the artist. After laying a wet plaster, composed of lime and sand, the painter must quickly apply the pigments before the surface dries, so that it absorbs the colors.

Peinture aux Cadeaux (xenia)

Early Imperial [27 / 235]

The painted decoration of a room in the Xenia house was reconstructed thanks to fragments of plaster collected during the demolition of the building. The restored panel shows a still life painted on a small board with flaps and suspended by ribbons. It depicts a rooster, with its legs tied, on a shelf with two fruits; a jug decorated with a ribbon, two fish and a hare (on the right) are in the foreground. These are gifts of hospitality (xenia) offered to one's host, suggesting that this room was a reception or dining room. A white bird, perched on the frame of the painting, gives the whole a striking relief effect.

Élément architectural en réemploi

Early Imperial [27 / 235]

Throughout history, the reuse of architectural elements is common in construction. It allows for the construction and decoration of architectural structures at a lower cost, by replacing elements from buildings that have lost their meaning and therefore their usefulness. This architectural element from a wall on the Roman quay in Marseille was thus originally a relief decorating an early Roman mausoleum, located near a city gate.

Bas relief du pavillon soviétique de 1937

Contemporary period [1789 / nowadays]

In 1937, France hosted the International Exhibition of the Arts and Techniques of Modern Life. Each country builds its own pavilion and the Soviet Union adorns its own with sculptures made by Joseph Tchaikov, a figure of Soviet realist art. In this architecture, which has become a work of propaganda, the eleven figures each represent an allegory of a Soviet republic and testify to the immensity of the country. Following the International Exhibition, the Soviet Union donated the sculptures to the Metalworkers' Union, which placed them on its property in Baillet-en-France. In 2009, excavations conducted in the park of the castle allow the rediscovery of these sculptures.

Architecture features

Architecture features

Initially conceived to provide a place to sleep, a place of rough protection or even a burial ground, the architecture was quickly developed for more specific functions. The ways in which these places were occupied sometimes provide material traces (artifacts and/or ecofacts) that allow archaeologists to specify the function(s) as well as the period of use of the places uncovered during excavation operations. This part will therefore focus on recontextualizing the objects in an architectural framework that has most often disappeared.

Mesolithic flint

Mesolithic flint

Before becoming one of the most important materials for building, stone was first of all a privileged source for the production of tools. The sometimes complex chain of operations in which they are used, from the preparatory work on the nucleus to the actual cutting, requires the creation of a dedicated space, the cutting workshop. Its study is made possible by the discovery of archaeological levels still in place that allow to account for concentrations or constraints (wall effects) that can then testify to an architecture in light frame of which we know some evidence from the Paleolithic.The study of waste cutting that litter the floor of the workshop allows archaeologists to restore the techniques used to arrive at the tools presented here. It is for example the reassembling of the waste of size associated with the experimentation which made it possible to highlight the use of indirect striker for these Mesolithic microliths.

Moulin à grain catillus et méta

Protohistory [- 2200 / - 50]

"Grain mill composed of 2 parts: the fixed lower part or ""meta"" and the mobile upper part or ""catillus"". The two parts are made of two different materials (sandstone and granite)".

archaeological context

After the Roman conquest, the Gallic farms known as aristocratic were abandoned in favor of the villae. The villa is above all a center of agricultural production which includes spaces of culture or breeding in its pars rustica but it is also a place of storage and habitat in its pars urbana. This habitat is very often associated with a bathhouse, reflecting Roman hygiene practices.

This evolution in the way of occupying space is also reflected in the techniques used since the local architecture goes from a wooden frame filled with cob the almost systematic use of stone for the building bases when it is not for the entire elevations.

This cultural shift is also reflected in the appropriation of production or processing techniques employed. The presence of bipartite mounds, one of which is fixed (the meta, often made of hard rock) and the other movable (the catillus, often made of sandstone) is one of the main markers of this cultural change. On the one hand, because this type of domestic instrument is widespread and reveals that the evolution of practices is widespread, and on the other hand, because the different origin of the rocks of each of the two millstone parts reflects an economy that has become extra-local.

Statue de Sainte Agnès

Modern period [1492 / 1789]

Circa 1520-1530 Avesnois limestone, traces of polychromy The identification of the statue was made possible by the presence of hooves on the left side of the figure's dress: they are the remains of a lamb, the attribute of Saint Agnes, a Roman martyr of the 4th century. The young woman is richly dressed in the fashion of the early 16th century. The sculptor has taken care to render the details of the garment such as the right sleeve or the jewelry. The work was originally enhanced with polychrome (paint applied to the surface). The flat back and forward leaning head indicate that it was placed against a wall or in a high niche. The orange-pink color visible on the garment is called a filler: it is a product that is applied to the statue as an undercoat, before the color is applied.

archaeological context

The building with a religious vocation must serve several functions. Most often communal, it must be able to accommodate the members of the religion that inspires it and, through its decorations, remind them of the theological framework of this spiritual space. The architecture should therefore be ordered not to the search for aesthetics but to a sacred function. Nevertheless, the Middle Ages hired its best engineers and artists to try to create a median space with the celestial Jerusalem until it provoked a reaction of rejection, the Reformation, at the end of this period. The statue of Saint Agnes is a fine example of this artistic finesse in the service of the divine. Originally enhanced with bright colors, it must have been part of a more extensive decoration.

Funerary and memorial architecture

Funerary and memorial architecture

Alongside commemorative monuments such as honorary arches, trophies and even certain city gates, funerary architecture is part of a larger whole called "architecture of memory". Often centered on one or more individuals, they may be dedicated to a magistrate, a family, a private individual or religious figures. These buildings took on a particular importance in the Gallo-Roman period and continued to evolve in the High Middle Ages in a society that was now fully Christianized. We present here four of these monuments discovered during preventive archaeology operations and which illustrate the memorial stakes and the monumental strategy in Roman Gaul and medieval France.

Family mausoleum for the Valerii Rufi

Family mausoleum for the Valerii Rufi

This funerary mausoleum in limestone was discovered in 1998 in numerous fragments during excavations in Strasbourg. It is characteristic of the monumental and luxurious tombs of the Gallo-Roman elites and takes the form of an architectural niche framed by pilasters topped with Corinthian capitals. Inside were statues of the deceased, whose names were given in an inscription at the base of the ensemble: they were members of the Valerii Rufi family who lived in Argentorate, the ancient name of Strasbourg, in the first half of the first century AD. Inspired by Italian models, comparable family mausoleums are found in Gaul very soon after the Roman conquest, for example at Glanum (mausoleum of the Julii) or at Beaucaire (mausoleum known as the Isle of the Count).

Ornement de toit

Early Imperial [27 / 235]

This architectural element was uncovered in the old city of Marseille, during the excavation of the former Alcazar theater. The remains found in this area range from the Greek period (5th century BC) to the contemporary period. This architectural element representing a tragic mask surrounded by acanthus leaves recalls the world of theater. It is one of a large series of monumental acroteria (corner elements of a roof) of the same type that adorned the tombs of the aristocracy of the Gallo-Roman province of Narbonne. Originally serving as a crowning decoration for a burial mausoleum of the 1st century CE, it was reused in a later construction. This tragic mask thus refers to the practice of reusing architectural elements from antiquity.

Memoria

Early Middle Ages [476 / 1000]

This monumental tomb, known as a memoria, was located in the chancel of a single-aisled early Christian church built around the 5th century CE. The tomb is lavishly decorated with marble chancel slabs with originally polychrome scale decoration. Inside were two sarcophagi which in turn housed two lead coffins. Around the memoria, ostensibly placed in elevation next to the altar, were accumulated about fifty sarcophagi. This funerary practice is reminiscent of the medieval tradition of burial ad sanctos, i.e., near the saints who were supposed to grant the deceased protection after death. The local saints (not identified) are probably the two men buried in the memoria. Placed near an important communication route, this funerary church must have attracted pilgrims from all over early medieval Provence.

Stèle funéraire d'Ursacius

Early Middle Ages [476 / 1000]

Ancient and medieval burials could take much simpler forms than the monumental tomb or the grave placed inside the church. The vast majority of the population was buried in simple cemeteries, sometimes in sarcophagi. Erecting a funerary stele already required financial means since it was necessary to pay for the stone and the engraving. Very often, the stele alone constitutes the monument in memory of the deceased. This is the case with this early Christian epitaph from the first Christian cemetery in Laon. It is the funerary stele of a certain Ursacius. The Latin inscription, which surmounts a Chrism accompanied by the Greek letters alpha and omega recalling the beginning and end of the world, reads: VRSACIVS VIVAT IN DEO, "Ursacius lives in God."

archaeological context

This stele comes from the first known Christian cemetery in Laon.
