...and wall-makers and masons,

to mend the damage in the house of the Lord.

12 Kings 12:XNUMX

stories by stories Middle Ages. We continue to acquaint you, dear readers of VO, with the history of the Middle Ages and, above all, with the crafts of that time, and not just with crafts, but with those that are reflected in the illustrations of the “Book of the Twelve Brothers”, now stored in the fund of the city library of the city of Nuremberg. Today our story will touch on the construction professions, which were engaged in by the brothers from the charity house of Mendel, created by him in the XNUMXth century, and Landauer - in the XNUMXth century.




Brother Conrad, stonemason. The illustration from the "Book of the Twelve Brothers" clearly shows what tools he works with. This is a pick, a square and a measuring bar with a plumb line. Conrad is hewing a stone block with a pickaxe. There are two finished blocks on the floor. 1425 (Amb. 317.2° Folio 4 recto. Mendel I)

The profession of a stonemason in the Middle Ages was not only an honorable occupation, but also very profitable. Although even in the XNUMXth and even in the XNUMXth centuries in Europe the main building material was wood, even then many buildings were built of stone, and already starting from the XNUMXth-XNUMXth centuries. stone became the main building material for knightly castles, royal palaces, and for religious backyards - monasteries and cathedrals. So the demand for masons who knew how to hew a stone was exceptionally high at that time.

Thus, the construction of the castle of Beaumaris (1278-1280), erected in just 18 months, employed 2 people. Moreover, the king must daily provide each person working there with grain in the amount of half a liter, which is 000 hectoliters in six months. Meanwhile, his possessions could hardly produce such a quantity of grain in a year. That is, it had to be bought somewhere!

No less expensive was the construction of the castle in Dover (the most beautiful of the English castles of Henry II) - the XII century, which Maurice the Engineer created for him. The parameters of the castle are impressive: the walls are 5 to 6 m thick. Water is supplied through a system of lead pipes. Living quarters are prudently equipped with wardrobes. Two chapels were provided for prayers and confession. Three gates led to the castle, locked with iron bolts.

The cost of the castle was colossal: £4 for the keep, and £000 for everything else. So it is not surprising that Henry and his son Richard (the future Lionheart) were forced to stretch the payment for its construction by as much as 3 years.
And also a stonemason could be hired to build another cathedral, a stone bridge across the river, monastery buildings or fortress walls that surrounded a particular city.

Interestingly, the walls of castles and fortresses at that time consisted of three components: two parallel walls - the front sides - made of smooth hewn stone, and "broken stone", that is, filling the space between them with rubble, and this same "broken stone" was applied not just like that, but filled with lime mortar, filling all the cracks. Over time, the lime mortar hardened and turned into stone, and thus the walls acquired amazing strength. In addition, their thickness sometimes reached 8-10 meters!


Brother Hans, bricklayer. He is busy laying out a wall of hewn stone. At that time, the simplest crane with an arrow and a gripper was already used in construction, which, as we can see, is located behind a battlement. 1425 (Amb. 317.2° folio 31 verso (Mendel I)

By this time, the simplest cranes were already used in the construction of stone structures, powered by a “squirrel wheel”, which was turned by the people in it. That is, they tried to “mechanize” the work, since in the Middle Ages construction was carried out constantly.

The fact is that Christianity, which spread in Europe, needed premises where believers would gather for prayer and rituals. At first, Roman basilicas were used, which had previously been court or trade buildings. The interior spaces - the naves - were usually covered with gable roofs on wooden rafters. The ceiling in the basilicas was also supported by beams of logs, which did not allow them to be built large and spacious.


Early Christian basilica that stood on the site of the Roman Cathedral of St. Peter in Rome (modern reconstruction). Wide naves - halls - could only be covered with wooden beams

Then the builders learned to build domed basilicas, the most famous of which is the Hagia Sophia in Constantinople. However, building them was very difficult.

It was much easier to block the naves with stone arches, which made it possible to create large and spacious buildings inside. Thus, the Romanesque style in architecture was born in Europe, the hallmark of which was the many semicircular arches in the windows, and in the doors, and inside the building. And here it was simply impossible to do without cranes!


Tools of medieval builders. The carpenter worked the wood with an ax (a), a hacksaw (6), a bow saw (c), and used a rotary drill (d) to drill holes. The main tools of the mason were a double-sided hatchet and a chisel (e), on which he hit with a special construction hammer - a mallet (e)

However, arched ceilings tend to straighten up and destroy the walls on which they rest. To avoid this, the masters built the walls of the Romanesque cathedrals very thick, and the windows were made narrow, like loopholes. Additional strength was given to the walls by buttresses - triangular ledges made of brick or stone leaning against the walls. That is why the buildings of Romanesque architecture seemed squat and massive.

This is what the buildings of the abbey (a Catholic monastery headed by an abbot) in Cluny, founded in 910, looked like.

Now it is difficult to say what prompted the architects to change the semicircular shape of arches and vaults to lancet. Most likely, this was due to the campaigns of the Crusaders to the East, where arches were a common element of buildings. The Gothic style emerged in architecture.

The church of Saint-Denis near Paris (erected in 1137-1144) is considered the first Gothic building in France. Then Gothic cathedrals began to be built in other places. With the general architectural unity of Gothic structures: vaults and lancet window openings, towers stretching upwards and light graceful arches, each European country had its own Gothic style.


Brother Fritz is busy preparing mortar from a mixture of sand, lime and water. 1425 (Amb. 317.2° Folio 2 verso. Mendel I)

In order for the bricklayer’s work to go quickly, he needed assistants, both those who turned the wheels of cranes and those who prepared mortar for him, which required a cube more than cement is needed today, because it was also poured between the walls! After all, more than 15 thousand castles in Europe alone were built, not to mention the mass construction of Gothic cathedrals.

A characteristic feature of them in the same France was a spacious hall (nave) with side supports (buttresses) around the outer walls and chapels between them. According to this scheme, the following were built: Notre Dame Cathedral (1163–1330); cathedral at Chartres (1194–1260); Reims Cathedral (1225–1299), which became the site of the coronation of French kings; the cathedral in Amiens (1220–1269), etc. French cathedrals are easy to recognize by the presence of a large round window above each of the entrances - “roses” with lace binding.

From France, Gothic architecture spread to Spain, where cathedrals were built on the model of the French in Leon (from 1205), Burgos (from 1221) and Toledo (from 1226). Gothic cathedrals in Spain are squat and wide. The craftsmen who built them used artificial marble (gypsum), faience and turrets similar to Muslim minarets to decorate them.


Gothic in England. The development of Gothic architecture in England can be easily traced by the design of windows in cathedrals: each stage of English Gothic had its own style. In 1180-1280. there was an "early English" style (a). Then he was replaced by the "decorated" style (b) in 1280-1360, characteristic only of English Gothic. In 1350–1550 the actual English "perpendicular" style (c), not similar to European styles, spread. Its simplicity made it acceptable not only for cathedrals, but also for parish churches.

By the way, it was in Spain, in the relatively small city of Girona, that the Cathedral of St. Mary of Girona was built (completed in 1416) - the largest single-nave cathedral in Europe after St. Peter's Cathedral in Rome. So, the width of the nave of the Cathedral of Saint-Etienne-de-Saens is 15,25 meters, the Reims Cathedral is 14,65 m, the nave of the well-known Notre Dame de Paris has a width of only 15 meters, but the nave of the cathedral in Barcelona is as much as 22 m ! That is, it is only 2 m narrower than the nave in the main cathedral of the Catholic world.

In Portugal, the first Gothic building was founded in 1388. Due to the abundance of ornamentation, the local Gothic looks even more elegant than the Spanish.

The first Gothic building in Germany was the Church of St. Elizabeth in Marburg (from 1235). Majestic cathedrals were built in Freiburg (1260–1350) and Cologne (1248–1880). The latter was built by German craftsmen on the model of Amiens. These cathedrals do not have "roses", and the towers of the facade are very close to each other. In addition, Gothic cathedrals in northern Germany are built of brick.

In Italy, Gothic architecture flourished in the northern cities, while in the south there are no Gothic monuments at all, and in Rome there is only one. But Italy is rich in non-cult Gothic monuments: city halls, palazzo palaces and fountains in city squares.


The plasterer, also named Fritz and also a member of the brotherhood, is busy standing in front of the side wall of the house and applying plaster with a spatula he holds in his right hand, a small supply of mortar is on his pallet. To the right on the floor is a box with prepared plaster. 1425 (Amb. 317.2° Folio 30 verso. Mendel I)

Interestingly, fresco painting was widely used in Italy in the Middle Ages. Moreover, frescoes decorated not only churches, but also residential buildings. That is why it was customary to plaster the walls of buildings there both from the inside and outside.

By the way, it was customary to whitewash the walls of the same knightly castles and fortresses. And all because the latrines on them were very often arranged quite high on the towers and walls, so that the "grace of the womb" constantly polluted them. It was not very pleasant to look at the stripes on the walls, besides, they attracted hordes of flies, so they had to be whitewashed quite often too!

    This theory was put forward in the XNUMXth century by the famous British architect Christopher Wren in his work Parentalia. But elements of Gothic architecture in Europe appeared before the Crusades. Today, many historians are inclined to the version that the Europeans borrowed them from the Moors.

          Quite possible. True, Vika says that the style got its name in honor of the Goths - the ancient Germanic tribes.

    Payment in installments, that is. A year or two of construction, and 10-15 years of payment! Well the credit system was developed for such troubled times.

    They didn’t fill it, but crushed stone and rubble were squelched into the semi-liquid solution. This is very well shown in the films on the reconstruction of Guédelon Castle.

    It can be assumed that this is indeed the case. That there were architects among the crusaders. And then what did they see in the East - as professionals?
    Special structures without support columns, distributing the entire mass of the building on frames of swept arches, which not only freed the interior of the religious building from columns, making it lighter, but also saved building materials by reducing their consumption on the walls.
    We saw and appreciated the role of the load-bearing ribs of the building frame - the ribs. Which, in addition, made it possible to create a mysterious, incomparable atmosphere inside the cathedrals due to the quirkiness of the interweaving of arches and the play of light and shadow.

    Probably, the impression was very strong. And then in Europe there was a shift in architectural solutions in favor of ribs.
    The arch of the interior, created by ribs, became the main distinguishing feature of Gothic architecture. The presence of G-d should not press on a person with a huge pile of stones, it should elevate his soul to the heights.

            Viktor Nikolaevich, well, yes, well, yes ...
            Leaving aside 1638, "Discourses and Mathematical Proofs Concerning Two New Branches of Science" by Galileo Galilei.
            But what about the simplest definition of sopromat, according to which
            strength of materials is the science of the strength and reliability of machine parts and structures. Its tasks include the generalization of engineering experience in the creation of machines and structures, etc.
            Generalization! A generalization of empirical experience, which is sometimes more significant than plots scientifically built on a drawing paper or on a monitor screen.
            And then, in your opinion, it turns out that they built it as G-d put it on their souls. Oh, did it fall apart? And let's do it differently, but the head has already rolled off the shoulders, the duke is stern ...
            It wasn't like that. For thousands of years, starting from small, building experience has been accumulated, the generalization of which, with the mathematical base summed up under it, gave strength of evidence. The merit of this science is only that it allowed a wide range of people who want to realize themselves to be touched, in particular, in construction, excluding the caste approach to it and immediately giving serious knowledge on the subject. Construction ceased to be "The X-Files".

              Imagine it was. Through a lot of trial and error. The most famous example is the destruction of the amphitheater at Fiden in 27 AD, when, according to various estimates, from 20 to 000 people died under a collapsed structure, built with errors by a certain Atilius.
              And the strength of materials was by no means born by summing up the mathematical base for construction experience and its generalization, do not mislead the audience. Neither Hooke nor Euler were builders.

                But they were not even materials scientists!
                If by this we understand the study of the properties of various substances and their behavior under various loads and deformations.
                To the side:
                - And why did I get involved in this argument with the master? Now it's fading!

                  But they were not even materials scientists!

                  And materials science is completely out of place here. Materials science studies the structure of substances, electronic, thermal, chemical, magnetic, optical properties. But not mechanical - that is, the ability of a given object to resist external mechanical influences.
                  Hooke's law is the basic law of the theory of elasticity, expressing a linear relationship between stresses and small strains in an elastic medium.

    If we continue the assumptions, then in the commentary on the ribs that make it possible to form the high lancet vaults of the temple, I mentioned what an indelible impression such vaults could make on the Crusaders.
    Further, already in Europe, the impression was conveyed not only to the clergy (there is no doubt in their enthusiastic acceptance of the idea), but also to the really practicing architects. The latter doubted the ability of the ribs to sustainably bear the entire load of the building. It can be assumed that engineering calculations were made, which showed that lancet arches are not suitable for this - they will not stand it! The Crusaders didn't see everything.

    And then it was proposed to solve the problem of the stability of the building with ribs using buttresses.
    The buttress is the entire external support system that takes on a significant part of the weight of the Gothic building and relieves the load on the ribs, often completely. This is in contrast to the Romanesque style with its interior columns.
    The outer (outer!) supports that make up the buttress are called flying buttresses. This is a system of beautiful stone semi-arches connecting the walls of the building with external support pillars. Semi-arches transfer the load formed by the mass of the building to the pillars, as a result of which, theoretically, the building can stand forever. Moreover, the system of flying buttresses can be stepped, visually significantly increasing the size of the building for the outside viewer.
    Sometimes, to increase the stability of the entire building, such an architectural detail as a pinnacle was used - an elegant thin tower, as if made of lace with the addition of lead. There can be many such towers surrounding the cathedral and connected to it...
    It turns out that everything that we could, looking at a Gothic cathedral, consider architectural excesses, just details that create beauty - all this works for its strength and stability. And even terrible gargoyles are still working on this task - they are arranged in such a way that during the rains they divert water. In a word, they are included in the drainage system, therefore, in the life support system of the temple building.
    Such complex architectural decisions had to be made in order to preserve the sublime atmosphere inside the Gothic temple.

        Painted perfectly, only the painting has nothing to do with reality. A kind of architectural fantasy.
        The latter doubted the ability of the ribs to sustainably bear the entire load of the building.

        They rightly doubted, since the entire load from the building is carried by the foundation, and the ribs transfer the weight of the vault to the supports.
        The outer (outer!) supports that make up the buttress are called flying buttresses. This is a system of beautiful stone semi-arches connecting the walls of the building with external support pillars. Semi-arches transfer the load formed by the mass of the building to the pillars, as a result of which, theoretically, the building can stand forever.

        The flying buttresses are transferred to the buttresses by the lateral expansion of the vault. Such a design, unlike the dome, which transmits thrust directly to the ground, through the foundations, as in the Romanesque style, makes it possible to greatly lighten the walls and cut through them with large windows with stained-glass windows.
        Sometimes, to increase the stability of the entire building, such an architectural detail as a pinnacle was used - an elegant thin tower, as if made of lace with the addition of lead.

        Pinnacles are, first of all, an element of architectural design. And they gave stability to the building only when they were built as part of the flying buttresses, which served to increase the vertical forces on the buttresses. In these cases, they were sometimes weighted with lead.

      In the XII century - engineering calculations? Once Venya was here on the site, he liked to fill in about the ancient Slavic civilizations, but he didn’t think of that either.
      Can you briefly outline the methodology for calculating the lancet arch?

    Moreover, the king must daily provide each person working there with grain in the amount of half a liter, which is 1 hectoliters in six months.
    Why is grain measured in liters? Why not in pounds, bushels, etc.?
    Let's convert everything to moles. With proper skill, you can generally convert everything into joules or electron volts. Fortunately, the famous Einstein formula allows this even for a schoolboy (E=mc2).
