The article is devoted to the issues of mining and pretreatment of the column and the pedestal in the Piterlak quarry, loading the column on a barge and delivery to St. Petersburg. The basis for the article is an album of illustrations of the rise of the Alexander Column, made by A. Montferrand and a literary review. The admiration of many architectural structures of the 18th-19th centuries is caused by the question of how this could be done at that time, without the power of steam and electricity. There are no such questions about the constructions built after the middle of the 19th century -there were already many lifting mechanisms, photography documented the construction process, and the dug Suez Canal testified to the increased capabilities of humanity and strengthened engineering skills. No one doubts that the Eiffel Tower was built without the use of helicopters and the achievements of an antediluvian civilization, but in relation to the unique creation of A. Montferrand, i. e. the Alexander Column in St. Petersburg, there is a clear distrust in the reality of the achieved result — the column of more than 27 meters high, more than 3 meters in diameter and weighing more than 600 tons stands vertically on the end surface without additional supporting structures. This article, presented in three reports, is devoted to the attempt to mathematically justify the possibility of what was achieved at the level of knowledge, skills, mechanisms and technologies of the beginning of the 19th century.

The history of the engineering profession includes many events and achievements that raise doubts about their reality in modern people. These are the pyramids of Mexico and Egypt, megalithic structures in Peru, the Baalbek temple, etc. Aqueducts and viaducts, highways and bridges, fortifications and ships, the Greek fire and the Church of Hagia Sophia in Constantinople — all this gives an idea of the capabilities and skills of ancient engineers. The questions of who and how built these objects and why modern technologies cannot repeat it will always excite the inquisitive mind of the researcher. The admiration of many architectural structures of the 18th-19th centuries raises the question of how this was possible to be done at that time, in the absence of knowledge about the power of steam and electricity. The objects built after the middle of the 19th century do not cause such questions — there were already many lifting mechanisms, photography documented the construction process, and the dug Suez Canal testified to the increased capabilities of mankind and strengthened engineering skills. No one doubts that the Eiffel Tower was built without the use of helicopters and the achievements of an antediluvian civilization. However, in relation to the unique creation of O. Montferrand — the Alexander Column in St. Petersburg, there is a clear distrust in the reality of the achieved result: the column that is more than 27 meters high, more than 3 meters in diameter and weighs more than 600 tons stands vertically on the end surface without additional supporting structures. This article, presented in three reports, is devoted to the attempt to mathematically justify the possibility of what was achieved at the level of knowledge, skills, mechanisms and technologies of the beginning of the 19th century. The first report is devoted to the formulation of the initial data for each stage of production, transportation and installation of the Alexander Column from the standpoint of the possibility of performing rigging work. The basis for the answers is an album of illustrations of the rise of the Alexander Column, made by the great architect O. Montferrand, who is also reproached for the lack of engineering training.

The main goal of this study is to establish a relationship between the use of the portrait and the concept of celebrity, at the end of the 19th century, taking as a corpus of analysis a set of requests for photographs sent by letter to Zola, from correspondents located in different parts of the world. It is intended, through a qualitative analysis of this collection, to identify the functionalities and contexts within this set of correspondents requested these images, in order to understand the role that photography has taken in the symbolic construction process of this figure as a celebrity.

The materials are devoted to the consideration of the issues of transportation, edging and installation of the pedestal and the column on the Palace Square in St. Petersburg. In addition to the album of illustrations by A. Montferrand, the drawings of Adamini Antonio, Montferrand's assistant, are considered, clarifying some aspects of the ascent. The questions about lifting the Alexander Column sometimes include doubts about the possibility of processing a large granite massif without the use of mechanical equipment. However, familiarity with the methods of manual stone processing presented in various works should convince the reader of the infinite possibilities of a person with a chisel and a hammer, especially if you add to them the perseverance, ingenuity and resourcefulness of the Russian person. In addition, we should remember a somewhat forgotten, but highly respected word -master. The most responsible and spectacular work was the lifting of the Alexander Column, which was the result of a lot of preparatory works. The construction of the platform and the inclined overpass was only part of them. A stone mass was built around the pedestal, which served as the basis for placing the capstans in two concentric circles. After the installation of the column, the finishing of the monument to the final dimensions, grinding and installation of the angel on the top were carried out for two years. Very little is known about these operations, but the presence of scaffolds made it possible to perform work at any height in any weather, and the possibility of processing granite and diabase, and their grinding has already been recalled. The installation of the angel sculpture without the use of hydraulic cranes and helicopters is hopefully no longer in doubt. The next day after the installation, they began to disassemble all the wooden structures. Stairs were built around the main vertical risers. After installation, the stonemasons continued to work with the column. For several months, more than 200 people worked simultaneously. They cut the belts left on the monolith for rolling and lifting, carried out the final finishing according to precise patterns and polished the stone. This article is devoted to the attempt to mathematically justify the possibility of what was achieved at the level of knowledge, skills, mechanisms and technologies of the beginning of the 19th century.

AbstractA thematic analysis of the manuscripts which were read, copied and written by the monks, the paper raises the issue of education and knowledge amongst the members of the Greek Catholic congregation of the Basilians of al-Šuwayr (Mount Lebanon) during the 18th century, a time in which the order constituted an intellectual centre in Syria, although its influence remained mainly restricted to the own communiy. Despite all efforts the level of knowledge remained—compared with European standards—low. But the monks nevertheless developed a basic attitude, which was important for the introduction of modernity to the Arab world in the 19th century. They had broad interests beyond the narrow limits of their own religion and did not assume from the start a disapproving attitude towards the knowledge and inventions of the West. These were decisive preconditions for a process of learning that had become imperative if the Orient wanted to close the quickly widening scientific gap between East and West.

Egypt has always attracted the attention of researchers as one of the oldest centers of civilization; many historical, geographical, cultural and religious studies have been devoted to its study. Taking into account the fact that the Arab Republic of Egypt occupies a leading position in the modern Arab East, more attention in historical and cultural studies is paid to the problems of the formation of Egypt, the history of its political, socioeconomic, cultural, literary and religious movements of modern and modern times. However, the processes of urbanization in Egypt today are on the periphery of sociocultural research, they are not given due attention. The beginning of the 19th century and the reforms of Muhammad Ali, as well as the construction of the Suez Canal, can be considered a conventional starting point for urbanization. The scientific article shows a direct relationship between the construction of the Suez Canal and the processes of Europeanization of the country launched by Muhammad Ali and his successors. The creation of large European cities, the impetus for the development of which was given by the construction of the Suez Canal, was subjected to a detailed analysis.

In this paper, we analyse features of the grammatical descriptions in Manchu grammar books from the Qing Dynasty. Manchu grammar books exemplify how Chinese scholars gave Chinese names to grammatical concepts in Manchu such as case, conjugation, and derivation which exist in agglutinating languages but not in isolating languages. A thorough examination reveals that Chinese scholarly understanding of Manchu grammar at the time had attained a high degree of sophistication. We conclude that the reason they did not apply modern grammatical concepts until the end of the 19th century was not a lack of ability but because the object of their grammatical descriptions was Chinese, a typical isolating language.

Levantine immigration to Chile started during the last quarter of the 19th century. This immigration, almost exclusively male at the outset, changed at the beginning of the 20th century when women started following their fathers, brothers, and husbands to the New World. Defining the role and status of the Arab woman within her community in Chile has never before been tackled in a detailed study. This article attempts to broach the subject by looking at Arabic newspapers published in Chile between 1912 and the end of the 1920s. A thematic analysis of articles dealing with the question of women or written by women, appearing in publications such as Al-Murshid, Asch-Schabibat, Al-Watan, and Oriente, will be discussed.
