THE IMPACT OF THE CONSTRUCTIVE SOLUTION ON THE FORMATION OF THE PORTAL IN THE ARCHITECTURE OF ARMENIAN CHURCHES OF 4TH-7TH CENTURIES
The article refers to the issues of decorative elements in architecture. The aim of the paper was to reveal the interaction peculiarities of the constructive and artistic solutions of the formation of the portals of the Armenian churches of 4th-7h centuries. The analysis of the process offormation allowed for carrying out the typological classification of the portals from the point of view of the transformation and development of the lintel construction. The classification showed that the portal created as a decoration of the entrance, as a result of the evolution of compositional-structural components was transformed into a unified constructive-artistic element, which has become the main type used in the later periods of the Armenian medieval architecture. The revealed features of the interaction of decorative and structural elements can be useful in the field of heritage studies and in the development offurther works on the formation of decorative elements.
Keywords: portal, structural, decorative, element, architecture, development, formation, churches, Armenian, 4th-7h centuries.
Introduction
The development of medieval Armenian architecture according to the periodization accepted in the scientific circles is classified into three periods: 4th-7th - Early Middle Ages; 9th- 11th and 12th- 14th centuries -Developed Middle Ages and 17th- 19th centuries - Late Middle Ages [14]). The latter are conditioned by political, public and socio-economic events, which were important for the history of the country and have left a certain mark on the development of the architecture and the art.
The period of 4th-7th centuries takes a special place in this context. This period in the history of Armenia is characterized by significant changes in the life of the country. In the 3th-4th centuries, feudalism replaced the slave-owning system. Feudal-princely dynasties were strengthened, inheritance rights were defined. In parallel with the new socio-economic and political conditions, the pagan faith gave way to Christianity, which in 301 was recognized as the state religion of Armenia. Under these circumstances, in parallel with the civil structures the construction of worship buildings, which were designed to serve the requirements of the new religion, was in full swing. And it was during the 4th-7th centuries that the main types of churches were developed and brought to life, which are the basis of the entire medieval religious architecture of Armenia [35, 38, 13, 37, 26].
As it has been noted by Sh. Azatyan, the architecture of Armenian churches, among other qualities, stands out for its structural meaningfulness and logical moderation of decoration [3]. At the same time, the fact that the portal is one of the important symbolic components of medieval church structures is undeniable [9, 2, 5, 25]. In the general context of the mentioned, it can be noticed that the portal, which became the main element of decoration in the architecture of the churches of medieval Armenia, is of interest both in terms of structure and aesthetics. And although the constructive-artistic solutions throughout the entire Middle Ages generally stand out with the logic of indissoluble unity, that integrity passed its unique way of formation in the early medieval period. This paper is dedicated to the coverage of the interrelationships between structural and artistic solutions in this complex process.
The aim of the article is to analyze the process of formation and evolution of the architecture of the portal of the Armenian churches of 4th-7th centuries and to reveal the interaction peculiarities of the constructive and artistic solutions within the framework of its formation.
The work was carried out on the basis of field observations, as well as research of published and archival materials on the topic, by scientific methods of theoretical research, comparative analysis, classification and generalization.
The elaboration of the article was based on the separation of certain problems related to the topic and the study of scientific literature on them. The following issues have been examined: the essence, peculiarities and periodization of the Armenian medieval architecture [35, 40, 37, 26, 14]; the architecture of specific Armenian temples, historical information on them, measuring materials and restorations [31, 36, 21, 27, 17, 8, 34, 24, 16]; the architecture, decoration and artistic elaborations of the Armenian medieval portals, the restorations developed on the basis of the comparative analysis and the excavation results [13, 31, 41, 36, 27, 23, 33, 19]; the results of the field observations of the Armenian portals of the 4th-14th centuries, general analysis, systematization, chronological and typological classification [3]; graphic and analytical information on the monuments outside the Republic of Armenia [38, 37, 19, 10]; general issues on portals in the medieval architecture [9, 2, 1, 5, 25] and in particular, the structural and artistic issues of the lintel [28, 6, 4]; some features of the formation of the structural solutions for coverings [12, 20, 22]; structural issues and stone architecture [7, 18, 30, 32, 29, 11]; implementation principles of stone structures with small elements [39].
The photos used in the figures were taken by the authors, in some cases the materials from Sh. Azatyan's personal archive were used. The drawings of the portals were made by the authors on the basis of A. Sahinyan's, T. Marutyan's, S. Mnatsakanyan's, N. Tokarski's reconstruction materials, as well as their own measurements. In the case of the portals of Yereruik and Arutch temples, the original measurement drawings made by Sh. Azatyan were used.
The article has been elaborated based on a study of the 51 portals belonging to 20 early medieval Armenian churches. The geography of the study is mainly limited to the central and north-eastern borders of Ayrarat Province of Greater Armenia (Mets Hayk), which includes a significant part of the present-day Republic of Armenia and covers the 4th-8th centuries Dioceses Ayrarat, Arsharunik, Vanand, Bagrevand and the northern part of Basen (Fig. 1). This is due to the historically central importance of the province, as well as the problems of access to the monuments in the current geographical and political situation [10].

The general chronological-typological classification of the portals of Armenian medieval monumental structures shows the formation patterns for the period of the 4th-7th centuries [3]. According to that classification, there are two main types of church portals in 4th-7th centuries (Fig. 2). The first type is the rectangular opening, on both sides of which are placed pylons protruding from the plane of the wall, connected by a horseshoe arch with a pediment covering. This simple but compositionally expressive form of the portal, as a result of the constant development of creative thought and constructive solutions, comes in its numerous varieties in 4th-7th centuries (Kasagh, Yereruik, Ptghni, Avan, Zvartnots, Talin (Cathedral) and other churches). And from the 6th century, another type is also used, which is created by removing the pediment from the portal covering. Such a solution can be seen in the Yeghvard, Mren, Talin (St. Astvatsatsin) and other churches.

Both of the above-mentioned types of portals of the 4th-7th centuries generally consist of the same two main compositional-structural components. The first is the decorative volume of the portal protruding from the plane of the wall. Having a variety of decoration of the details, it retains the basic compositional elements that make up the volume: bases, pylons, capitals and an arch (with or without a pediment). The second is the part of the wall between the decorative volume and the door opening, within which the covering of the door opening is carried out (Fig. 3).
The issue of the constructive relationship between these two components, as noted in the study dedicated to the Palazzo del Priori portal damages, as a problem of construction mechanics is of great importance from the point of view of the portal structure formation [4]. It is noteworthy that in the vast majority of the portals of this period, as the examination of the examples below shows, the decorative part is built independently and does not participate in the distribution of the load coming from the wall of the structure.
And in this sense, the constructive solution of the door opening covering is of special interest. It has had a significant role in the development of portals, their formation processes, as this is where the decorative and constructive problems of portals are mainly related [28].

The second element that forms the portal, the part of the wall, comes in a number of variants, which are the result of the gradual development and transformation of the lintel construction. Despite the development of stone arch and vault constructions in 4th-7th centuries [18], the door opening continues to maintain the rectangular solution. This leads to a peculiar development of the lintel construction. And the rectangular shape of the opening, which is necessary for the installation of the door and its convenient operation, is decisive both for the development of the lintel construction and for the whole portal formation.
The peculiarities of the development of the lintel constructive system can be revealed by observing typical examples.
Beam. The rectangular door opening in the portals of the earliest churches of 4th-5th centuries is covered with a full single-piece stone beam. In general, coverings with such constructive system have been implemented since ancient times, a vivid example of which is the widespread dolmens in the Eurasian continent - burial and cult structures [12, 20, 22]. This system has existed in Armenian architecture until the late Middle Ages. However, in parallel with the creation of the large spans cover systems with significant advantages from the constructive and technological point of view, the beam model continues to be applied, especially in the case of small spans, such as portals. In particular, such a constructive solution has the western portal of the Kasagh Basilica, where the decorative part (almost not preserved on the spot, but the excavated fragments were the basis for A. Sahinyan's restoration) has a completely independent solution from a constructive point of view (Fig. 4).
The beam covering the door opening consists of two parts: external (frontal) and internal beams, which together cover the entire thickness of the wall. The width of the door opening is 1500 mm. Beams with a height of 750 mm with the same 750 mm size rest on the side walls of the door opening. The front beam is decorated with ornaments typical of the time.
The northern portal of the Avan Temple, the portals of the Tekor Temple, of Tsiranavor Church in Ashtarak and of St. Astvatsatsin Church in Talin have such a solution (Fig. 5).
It should be noted, however, that in this system, from the point of view of the structure operation, the lintel stone is in a rather unfavorable condition. It bears all the load of that part of the structure wall, as a result of which cutting forces appear in the supporting parts of the beam, the impact of which increases sharply, especially under the influence of earthquakes or ground settlements [4, 30, 32, 29, 11]. The study of the portals of different churches shows that the mentioned defect is discovered by builder-architects quite early, and
attempts to solve the problem are already noticeable in the structures of almost the same period, which are expressed in other approaches to the implementation of the lintel.

Slot. In the 4th-5th centuries, in parallel with the widespread beam covering, another type of door opening covering was created. It is expressed in the system of lintels with unloading slots. The slots are implemented
between the stones of the first and second rows of the lintel, on the stone of the second row. Due to the slots, the lintel stone is released from the directly affecting load, and all the weight coming from the wall is transferred directly from the stone of the second row to the lateral parts of the opening. Here the lintel turns into a self-bearing constructive element that ensures the rectangular opening of the door. Interesting examples from the point of view of the construction and artistic design of this type of covering on the church entrance are the southern and western portals of the Yereruik Temple (Fig. 6).
Fig. 6. The right side portal on the southern facade of the Yereruik Basilica (5th century, Anipemza, Shirak Province, Republic of Armenia): A) facade (according to Azatyan Sh.R., Portals in the Monumental Architecture of Armenia in 4th -14th centuries, Yerevan, Sovetakan Grogh, 1987, p.58, plate 1, the original drawing used); B) general view
The opening of the western portal door with a 1560 mm span is covered with two large lintel stone blocks - external and internal. The unloading slot is implemented on the second row of blocks, within the whole depth of the wall and has 35 mm height. The artistic development of the lintels on the temple portals is closely connected with its construction. In all three portals, the stone of the first row of the lintel, which is separated from the other rows by an unloading slot, is developed in detail. Such a design of developing the lintels ensured the originality of the artistic expression of the portals [21, 8].
However, it should be noted that the unloading slots, while improving the construction of the lintel, do not give a complete solution to it. Covering the doorway with large stone blocks is of technological and construction difficulties and lags behind the development of construction techniques of the time, where the principle of implementation of structures (walls, arches, vaults) by relatively small elements is already widely used [39]. And such an approach to covering the door opening as in Yereruik Temple was later left out of the portal implementation practice and was found in the structural solutions of smaller internal doors of the buildings, as in the case of the 4 internal doors of Avan Temple (Fig. 7). It should also be noted that the decorative part in the portals of Yereruik Temple is also independent and does not take part in the general operation of the wall structure.

Lunette. The logical continuation of the unloading slot is the lunette applied in the practice of construction of the portals of already 6th-7th centuries. From the engineering point of view, lunette plays the role of the slot. In this case, the constructive principle of releasing the lintel stone from direct load remains unchanged, only the stones of the second row of lintel complicated from the point of view of technology and construction, are replaced with an arch, which also has an advantage in terms of reliability [6]. In particular, an example of the lunette use is the western portal of the Avan Temple (Fig. 8). This example, however, manifests that the lunette solves a partial problem in the construction of the lintel. Although the lunette arch bears the load of the wall, the self-supporting stone of the lintel required for the installation of the rectangular door, which is preserved in this type as well, is in a rather unfavorable condition from the constructive point of view. The span part of the beam is free from bottom and top parts, and at the edges - in the supporting parts, it takes the forces coming from the arch. In the case of large spans and large dimensions of structural elements, a vivid example of which is the western portal of the Avan Temple, damages occur under the influence of cutting forces during seismic tremors [7]. These become the reason for the implementation of an additional wall section in the doorway opening of this portal later (Fig. 8).
Examples of the application of lunette are also found in the portals of the Zvartnots Temple and the Jrvezh Church (Fig. 9). In Zvartnots Temple, which is one of the most important monuments in the field of Armenian church architecture, all 5 portals have similar solution: they all have lunette [17]. It should be noted that according to A. Yeremian's comparative analysis, there were portals with such a solution in St. Hripsime Church (618, Vagharshapat, Republic of Armenia). However, they were later substantially changed and complete facts on original solutions were not preserved [41].

facade of Jrvezh Church (7th century, Jrvezh, Kotayk Province, Republic of Armenia: according to Tokarsky NM, Jrvezh, Yerevan, Academy of Sciences of the Armenian SSR, 1959, p.57, Fig. 20)
Closed Lunette. The application of lunette creates a new type of portal with unique artistic expressiveness. However, this option of covering the door opening does not become widespread as well. It can be assumed that one of the reasons for the rejection of this covering method were the difficulties related to closing the opening in the lunette part.
The problem of closing the lunette opening is evidenced by the fact of implementation of stone masonry in those parts later, as well as the creation of closed lunettes, where the lunette is replaced by a stone block with a circular top part. An example of this is the western portal of the 7th century Mren Temple (Fig. 10).
Fig. 10. The covering structure of the western portal of the Mren Temple (640, Kars Province, Republic of Turkey)
This, being an example of a closed lunette, is at the same time quite one of a kind. Here the lintel stone is not rectangular but trapezium-shaped. The width of the stone closing the lunette is smaller than the door opening and is also smaller than the size of the upper zone of the trapeziform lintel. Both of these stones are carved with bas-reliefs with unique religious and secular motifs. The portal on the northern facade of the Temple has the same solution [19].
There are portals with closed lunette also in Lmbatavank. The application of such a solution can also be found in the inner doors of the churches, in particular, in the sacristy entrances of the Ptghni Temple (Fig. 11).

Beam and Arch. Another approach to the lintel unloading is the combination of different solutions in two layers of the wall masonry (external and internal). In this case, the beam carrying the load from the wall is preserved in the external part, and an arch of a size of the door opening is implemented in the internal part. Such a solution can be seen in the portals of the Arutch Temple (Fig. 12). These are implemented in a form of a niche-portico covered by span roof with the appearance of a pediment. This serves both the purpose of protecting from various weather conditions and, apparently, of forming appropriate psychological preparations before entering the temple [1]. In the lintel part, there is a masonry with a semicircular top consisting of three stones, of which the lower beam stone bears the load of the external layer masonry of the wall. The covering of the door opening implemented in a form of a semicircular arch from the inside, which is the direct support of the internal layer masonry of the wall.

It should be taken into account that the presence of a portico at the Arutch Temple portals, however, does not affect the solutions of the opening covering, and the decorative part of the portal does not bear the load of the external layer masonry of the wall in any way. And the mentioned, in fact, also refers to the portals of all the churches already discussed. Here, the components of the decorative part of the portal - arch, vault, pediment, pylol, base, capital are all inserted in the wall slightly or are placed in front of the wall [33]. They do not directly participate in the transfer of the load of the entire wall height to the ground, and the elements of the upper zone generally rest on the construction of the door opening lintel.
Unloaded Tympanum. A direct consequence of above-mentioned approaches to the closed lunette and the combination of beam and arch in two layers of the wall masonry can be considered the creation of a new type of door opening covering, where the stone of lintel beam as well as the stone closing the lunette are united in one block - the tympanum stone. Such a solution can be seen in the portals of the 7th century churches
Mankanots in Oshakan, Karmravor in Ashtarak, St. Astvatsatsin in Voskepar and Katoghike in Talin (Figures 14, 15).

A) The portal on the western facade of the St. Astvatsatsin Church (7th century, Voskepar, Tavush Province, Republic of Armenia); B) the portal on the western facade of the Mankanots Church (7th century, Oshakan, Aragatsotn Province, Republic of Armenia); C) the portal on the western facade of the Karmravor Church (7th century, Ashtarak, Aragatsotn Province, Republic of Armenia)
Both portals of St. Astvatsatsin Church in Voskepar have this solution. Here the decorative volume is completely independent of the tympanum. The tympanum of the western portal has cracked in its entire height under the weight of the upper part of the wall [16]. Both portals have an arch of a size of the door opening on the inside (Fig. 14a). The tympanum of the portal of the Mankanots Church in Oshakan has the same solution (Fig. 14b).
In the tympanum of the portal of the Karmravor Church in Ashtarak, the ratio of the tympanum and the decorative section is more obvious and clear, as the decorative part of the portal is missing, due to which the constructive solutions of the door opening part of the wall are visible. The tympanum has wings at the edges, on which the arched stones placed above the tympanum rest. There is an arch of a size of the doorway from the inside (Fig. 14c).
In the Talin Cathedral portals, which have a portico solution like the Arutch Temple ones, the door opening covering is externally implemented with the above-mentioned tympanum stone block, and internally, as in the Arutch Temple, with an arch. The tympanum stone, which has wings in the bottom part, is developed from two sides, externally for the facade and internally for the interior. Here the internal arch is semicircular, the height is less than the height of the tympanum and acts as a support for it (Fig. 15).
The tympanum created by the mechanical union of two constructive elements (the lintel beam and the stone closing the lunette) had partial defects. The first is that rectangular wings inertially left from the lintel are of no constructive significance. The second is that these wings hinder the complete implementation of the arch built above the tympanum, which in turn prevents the complete unloading of the tympanum. Tympanum stones of the Talin Cathedral typically have cracks along the entire height of the rectangular wings (Fig. 15).
It should be taken into account that the covering solution for the Talin Cathedral portals differs significantly from the versions of Mankanots in Oshakan, Karmravor in Ashtarak and St. Astvatsastin in Voskepar. Here, the stones of the arch built above the tympanum are exactly the stones of the decorative part, which are no longer inserted in the wall, but go deep inside, taking the load of the external layer of the wall (Fig. 15).
This allows us to prove that the creation of this type of door opening covering is a turning point in the formation of portals. If before that the decorative volume and the part of the wall that made up the covering of
the door opening were independent from the structural and constructive point of view, here the portal arch, while preserving the decorative function, at the same time bears the load of that part of the wall and becomes a constructive component, leaving to the tympanum stone only the functions of insulation and giving a rectangular form to the door opening.

It is noteworthy that this new type of tympanum which gives new opportunities of artistic design and is more reasonable from the constructive point of view, undergoing some improvements (the wings left from the lintel beam are removed, which allows the implementation of a complete load-bearing arch, in the supporting parts the tympanum corners intersect at 45 degrees, as a result of which the cutting forces at the edges are eliminated), becomes primary in the Armenian medieval monumental architecture and greatly widespread in later centuries [40, 13, 37, 3, 34, 24].
Summary and Conclusion
The analysis of the development of the portal architecture of the Armenian churches of the 4th-7th centuries based on the methods of theoretical research, comparison, classification and generalization allows revealing some regularities of the interaction of constructive and artistic solutions in the process of portal formation. In particular, from the point of view of the transformation and development of the lintel construction, it is possible to make a certain typological classification of the portals of 4th-7th centuries Armenian churches (Fig. 16).
The classification shows that although from the point of view of the lintel structure there is a certain evolution in the typological transformation process of the portals, it does not have a clear, definite direction. Originating from the ancient beam type, it has in parallel led formation of new types expressing the attempts to unload the lintel, which, however, did not exclude the use of the beam type. At the same time, as a result of this multilateral process, the preconditions for the structural-artistic unity of the architecture of the portals were formed, which became primary in the further Armenian medieval architecture.
In particular, the classification makes it obvious that significant changes and differences in the lintel construction appear in the second element that forms the portal - in the wall part and depend on the constructive solution of the lintel. While following the development of the forms in the tympanum part, the desire to find a more structurally stable, reliable system for covering keeping the rectangular form of the doorway becomes obvious. As a result, there are changes in the structural role of the two main compositional and structural components of the portal - the decorative and wall parts. The decorative part is included in the constructive
system of the structure wall, and the part of the portal wall covering the doorway becomes a self-supporting tympanum, free from the load of the structure wall.

Fig. 16. Typological classification of the portals of Armenian churches in 4th-7th centuries according to the transformation and development of the lintel construction
Thus, it can be stated that the portal, which was a form of a decorative design of the entrance in the architecture of the 4th-7th centuries Armenian churches, acquires a new artistic expression at each stage of the lintel construction evolution, and, taking the functions of bearing the covering as well as the applying hardness to a wall weakened by the doorway, becomes a unified constructive-artistic element.
