The article attempts to analyze the socio-economic issues surrounding the development of the city of Novy Ostropil as one of the urban settlements on the territory of south-eastern Volyn in the middle of the 18th century. During this period, the city received confirmation of royal privilege for self-government and continued to use it in solving everyday problems of Magdeburg law. Novy Ostropil was owned by Franzyshko-Ferdinand Lubomyrskyi, who leased it for three years to Barbara-Ursula Sangushko in the middle of the 18th century. For this purpose, the rental inventory of the city was compiled in 1751 and has survived to our time. Therefore, the city first became the object of the profits of its owners and tenants. The agricultural sector played a critical role in the life of the city. Based on the inventory, a detailed architectural image and layout and a list of the buildings in the stockade were restored. The latter were made of pine and oak wood, some elements were made of linden, and the roofs were covered with straw, etc. Among the buildings in the Filvark complex was "Izba", which housed Governor S. Chernetsky. Vinnytsia was one of the city's Filvark structure's profitable objects. The city worked in the city "Entrance" on "Khmelnytskyi Black Way", where its exterior and interior were presented. On the river, Sluch’s two mills are arranged according to two and three millstones with steps and foils. 201 households in the city were recorded in the inventory (86.5% were Christians and 13.5% were Jews). Ukrainians dominated here, followed by Poles, and there were the fewest Jews. The Jewish communities of Novy Ostropil and Old Ostropil did not create a single kagal. It was divided into two separate parts, each of which was part of the Kagali of the two nearest cities, Lubar and New Polonny. The number of Jews in Novy Ostropil during 1751–1765 decreased significantly. Based on the analysis of the inventory, it was possible to obtain separate information about the Ostropil artisans and professional classes of residents of this city. The profession of a shoemaker was among the most sought-after and popular, followed by coopers. The occupation of crafts did not yet give a full opportunity to break with agriculture. 9.5 percent of the city's residents had liberation from general payments and work. In exchange for this, they were engaged to perform certain functions in the structure of the city's economy. Townspeople living in tenements made up 9.5% of all residents of Novy Ostropil. They were exempted from general city boards and individual duties, but not all. Craftsmen and those engaged in crafts (carriers, millers, winemakers), church ministers, etc., dominated among the peasants. As a whole, in the economic development of the city, primacy belonged to the agricultural sector; therefore, Novy Ostropil should be interpreted as an insignificant urban centre of the agrarian type.

The bracelets with zoomorphic terminals are analyzed in the paper. They were found in the West Baltic Ostriv burial ground in 2017—2020. The work shows types of jewelry, their style, and history of research.
The assemblage of 15 samples has dissimilar configuration. Furthermore, 10 of them were found in female burials, 2 — male burials, 1 — archaeological level and 2 are accidental finds. These bracelets have arcuate shape, terminals with stylized reptile heads. Their surface is decorated with a geometric ornament that emphasizes the overall zoomorphic motif and mimics the reptile in motion.
According to L. Vaitkunskene’s typology, the collection of Baltic zoomorphic bracelets from the Ostriv burial ground can have four types.
Because of this features, such as overall tendency developing shapes of products, specifics of application of geometric ornament (advantage of combination of lines and circles on the surface of bracelets from Curonian area; dominance of geometric figures in ornamentation of Daugava Livonians, Selonians and Latgalians), and their chronology, the collection of Baltic zoomorphic bracelets from the Ostriv burial ground are similar to the West Baltic tribe of Curonians, the antiquities of the end of X — first half of XI century.
The author assumes that some of bracelets from the Ostriv burial ground were made directly in Porossya. He examined the samples of ones in full detail and found out that different pieces of bracelets have similar features. Foremost, they are the design of the stylized eyes of animal-headed terminals and the similarity of geometric plots, which, in general, do not have a bright variety and could be made by a certain master.
Summing up, further systematic research of burial ground Ostriv and the open-air settlement in the tract of Stari Sukholisy allows to growth available sources. It will promote a deeper understanding of various facets of the material culture of the Baltic immigrant community.

In 2017 the new burial ground on the right bank of Ros river between Puhachivka and Ostriv villages, in Rokytne district, Kyiv region was discovered. During 2017—2019 67 burials have been excavated there. Diverse and spectacular archaeological objects discovered during excavations — the spiral torques, cross-bow ladder fibulae of type Bliujiene V, penannular brooches with rolled terminals, poppy-head terminals, funnel-shaped terminals, star-shaped terminals and widening terminals, bracelets with zoomorphic terminals, chains, temporal-rings and rings — all these grave goods are typical to Western Baltic tribes (Old Prussians, Curonians, Skalvians). The burial assemblages with weapons compose the notable number. Buried men were equipped with axes, spears, pila. As M. Plavinsky stated using of the pillum was the feature of Baltic military-technic tradition. In generall the weapons discovered in the Ostriv burial ground points to the prevalence of infantry in that community. This allows suggest that people buried in the Ostriv burial ground were the warriors of Ros defensive line.
From historical point of view archaeological finds well illustrate and prove the chronicle evidences about activity of first Kyiv princes, first of all of Volodymyr the Great and Yaroslav the Wise, directed to the strengthening of the southern borders of Kyiv Rus. The lands of Ros basin historically were the border with steppe and the Ros river was a proper, natural defensive factor, the frontier between the world of settled farmers and steppe nomads. Kyiv princes traditionally placed here their military forces, defending the capital of Rus from nomadic charges. We believe that the Ostriv burial ground could be associated with the garrison of Stari Sukholisy hill-fort consisted of Western Baltic people.

The Ostreid herpesvirus 1 species affects shellfish, contributing significantly to high economic losses during production. To counteract the threat related to mortality, there is a need for the development of novel point-of-care testing (POCT) that can be implemented in aquaculture production to prevent disease outbreaks. In this study, a simple, rapid and specific colorimetric loop-mediated isothermal amplification (LAMP) assay has been developed for the detection of Ostreid herpesvirus1 (OsHV-1) and its variants infecting Crassostrea gigas (C. gigas). The LAMP assay has been optimized to use hydroxynaphthol blue (HNB) for visual colorimetric distinction of positive and negative templates. The effect of an additional Tte UvrD helicase enzyme used in the reaction was also evaluated with an improved reaction time of 10 min. Additionally, this study provides a robust workflow for optimization of primers for uncultured viruses using designed target plasmid when DNA availability is limited.

Ostreid herpesvirus-1 microvariant (OsHV-1) is a member of the family Malacoherpesviridae within the order Herpesvirales. OsHV-1 microvariants have been responsible for mass mortality events in commercially produced Pacific oysters (Crassostrea gigas) in Australia, New Zealand and Europe, since their first detection in France and Australasia in 2008 and 2010, respectively. OsHV-1 presents a significant threat to the Australian C. gigas industry (worth AU$53 million in 2007/08), with all age and size classes of C. gigas affected by the virus. Oysters <1 year of age are the most susceptible age class, with mortalities of 60% to 100% observed in France and Australia. Of great concern to the industry is the propensity of the virus to persist in a waterway after initial infection, resulting in recurrent, seasonal outbreaks of disease. The commercial production of C. gigas has ceased entirely in two key estuaries in NSW, Australia as a result of the recurrent disease caused by OsHV-1. The need to develop robust farm management strategies that will allow growers to produce C. gigas in the presence of OsHV-1 is apparent. In order to achieve this goal, a thorough understanding of the transmission and spread of OsHV-1, and the factors that lead to transmission and expression of the disease is required. One of the largest knowledge gaps concerns the transmission of the virus in the estuarine environment. This thesis was focused on addressing several of these gaps by assessing the transmission, detection and distribution of OsHV-1 in seawater, the occurrence of OsHV-1 disease outbreaks to identify periods of high and low risk, the persistence of OsHV-1 in farmed and wild oysters and the potential for them to act as sources of virus in subsequent outbreaks, and possible risk factors for OsHV-1 transmission and expression of clinical disease.

The high mortality and economic loss in farmed Pacific oysters (Crassostrea gigas) caused by the virulent microvariant genotypes of Ostreid herpesvirus - 1 (OsHV-1) has spurred research into strategies to mitigate the impact of the disease. The two aims of this thesis are i) to examine the effect of farm management and other risk factors on mortality caused by OsHV-1 during a natural outbreak and ii) to use a laboratory infection model for OsHV-1 that provides control of the environment to examine the specific risk factors and there interactions on mortality due to OsHV-1. Water temperature has a strong effect on OsHV-1 pathogenesis in Pacific oysters that could be leveraged to develop ways to reduce mortality due to OsHV-1 in commercial oyster aquaculture. Exposing oysters to OsHV-1 at a low water temperature (18°C) reduced mortality when oysters were subsequently exposed to OsHV-1 at a higher water temperature (22°C). The different pattern of expression of some immune genes at 18°C compared to at 22°C suggested that the response to OsHV-1 is influenced by different water temperatures and provided an insight into Pacific oyster immune function.

Le virus ostreid herpesvirus type 1 (OsHV-1), peut être considéré comme un des agents infectieux majeur affectant les élevages d’huîtres creuses, Crassostrea gigas, en France. Des différences de sensibilité à l’infection ont également été observées au sein de cette espèce. Des travaux précédents suggèrent un lien entre la base génétique et la survie des animaux face à l’infection. Dans ce contexte, l’objectif principal du travail de thèse était de mieux comprendre les interactions entre l’huître creuse et OsHV-1, et plus particulièrement, les bases moléculaires du cycle viral. Nos résultats montre que le virus est capable de se répliquer chez l’hôte quel que soit son stade de développement, et sa sensibilité. Cependant, la cinétique de multiplication est plus rapide chez des individus sensibles comparés aux moins sensibles. Il apparaît également que chez les individus survivants, le virus ne soit plus détectable après une phase de réplication active. Cette observation laisse suspecter (i) une rémission avec une élimination du virus ou (ii) une persistance du virus sans symptômes détectables. Ces résultats mettent en lumière la possibilité du virus de circuler au sein des individus survivants. Ces individus peuvent excréter des particules virales et intervenir ainsi dans le processus d’infection en milieu naturel. L’ensemble de ces résultats représentent une premier contribution à la compréhension du cycle d’ OsHV-1 chez l’huître creuse, plus particulièrement au niveau moléculaireIn France, Ostreid herpesvirus type 1 (OsHV-1), can be considered one of the major infectious agents in Pacific oysters, Crassostrea gigas. Susceptibility differences to infection were observed in this species. Previous work suggested that the genetic basis and the survival animals to infection were related. In this context, the main objective of this thesis was to understand the interactions between oysters and OsHV-1, in particular, the molecular basis of the viral cycle. Our results shows that the virus is able to replicate in the host regardless of its stage of development or its susceptible. However, multiplication kinetic is faster in susceptible individuals compared to less susceptible individuals. After a active replication, it would appear that the virus is no detectable in survival individuals. This observation suggests (i) a remission with elimination of the virus or (ii) a virus persistence without detectable symptoms. These results highlight the ability of the virus circulating in the host without causing mortality. These individuals can excrete viral particles and interfere with the infection process in field. All these results represent a first contribution to the understanding of OsHV-1 cycle in Pacific oysters, particularly at the molecular level

Crassostrea gigas est la principale espèce d’huître cultivée dans le monde. Depuis 2008, de sévères épisodes de mortalités affectent les huîtres âgées de moins d’un an en Europe et en Océanie et sont associées à l’émergence de l’Ostreid herpèsvirus μVar (OsHV-1 μVar). En Europe, ces mortalités sont saisonnières et surviennent lorsque la température de l’eau de mer est comprise entre 16°C et 24°C. Dans le cadre de ce travail, l’effet des hautes températures (21°C, 26°C et 29°C) est évalué sur la sensibilité des huîtres à OsHV-1 mais aussi sur la persistance et la virulence du virus. La survie des huîtres infectées maintenues à 29°C (86%) est supérieure à la survie des huîtres placées à 21°C (52%) et à 26°C (43%).Les températures élevées (29°C) diminuent la sensibilité des huîtres à OsHV-1 sans altérer l'infectivité du virus et sa virulence. L’exposition des huîtres infectées à 29°C pourrait réduire l’expression des gènes viraux et la synthèse de virions par la réduction de l’expression de gènes hôtes codant pour des protéines impliquées dans la transcription et la traduction, la réduction de l’expression de gènes impliqués dans le catabolisme, le transport des métabolites, et synthèse de macromolécules.Finalement, l’induction conjointe de l’apoptose, des processus d’ubiquitinylation et de la réponse immunitaire, pourrait permettre l’élimination d’OsHV-1Crassostrea gigas is the main species of oyster cultivated in the world. Since 2008, mass mortality events have been affecting oysters aged less than one year old in Europe and Oceania and have been associated with the emergence of the Ostreid herpes virus μVar (OsHV-1 μVar). In Europe, these events are seasonal and occur when the seawater temperature is between 16°C and 24°C. In this work, the effect of high temperatures (21°C, 26°C and 29°C) was evaluated on the susceptibility of oysters to OsHV- 1 but also on the virulence of virus.High temperatures (29°C) reduce the susceptibility of oysters to OsHV-1 without altering the infectivity of the virus and its virulence. High temperature could reduce viral infection and virus synthesis by reducing the expression of host genes that encode proteins involved in transcription and translation, catabolism, metabolites transport, and macromolecules biosynthesis. Finally, the induction of apoptosis, ubiquitinylation processes and immune response could lead to the elimination of OsHV-1

Pacific oyster mortality syndrome (POMS) is a high mortality disease which has negatively impacted oyster farming. Despite the causal relationship between OsHV-1 and oyster mortality, the incidence and severity of disease is determined by complex interactions between the physiology of oysters, the environmental conditions and secondary pathogens. Understanding the multifactorial nature of the disease is required to develop management strategies. Recently, changes in the microbiome of oysters were associated with POMS. It is important to identify if differences in the microbiome are an outcome of the pathogenesis of the disease or whether the features of the microbiome predispose or contribute to the severity of disease. This thesis focused on the influence of important environmental factors on the composition of the Pacific oyster microbiome and determined how this impacted the outcome of OsHV-1 infections in oysters. Research chapter 1 investigated how the microbiome of genetically related Pacific oysters with a common hatchery origin was different when they were grown in different estuaries. Using the 16S rRNA gene diversity, the different estuarine environments were shown to generate unique microbiomes which were also associated with a differential response to the OsHV-1 infection. The quantitative dynamics of total bacteria and Vibrio spp. during an OsHV-1 infection was assessed using qPCR assays. The microbiome changed with the environment and after an OsHV-1 challenge. A strong correlation was observed between the OsHV-1 and Vibrio quantities in OsHV-1 infected oysters. Different microbiomes responded differently with a differential outcome of OsHV-1 challenge. Optimizing the quality and quantity of bacterial DNA from oyster tissues to facilitate accurate identification of the microbiome proved critical for microbiome studies. Research chapter 2 focused on evaluating methods to sample tissues and extract nucleic acids from Pacific oysters to accurately determine the microbiome. These procedures substantially impacted the quantity and diversity of bacteria identified. The controlled environment of a laboratory experimental system has been utilized to understand infectious diseases of oysters including POMS. A period of acclimation to environment before an experimental study can induce changes to the microbiome that may confound findings attributed to the disease being studied. Research chapter 3 focused on assessing changes in the Pacific oyster microbiome during acclimation to a laboratory environment when oysters are maintained in constant immersion in water and in a simulated tide. The oyster microbiome changed during acclimation irrespective of the management strategy (constant immersion vs. simulated tide). Research chapter 4 discusses the impact of the environment on the microbiome of oysters subsequent to challenge with OsHV-1. Although the microbiome composition changed after viral infection, it was the same for constant and partial immersion and did not explain higher mortality in oysters in simulated tidal conditions. Knowledge of the role of environmental factors on disease expression can help direct advice on oyster farm management strategies. Seawater temperature plays a major role in triggering diseases in the marine environment. Research chapter 5 discusses the impact of temperature and temperature fluctuations in water on the oyster microbiome and how it affects the outcome of an OsHV-1 infection. Unlike with temperature fluctuations the microbiome behaved differently at higher temperatures (26 0C) but did not create any distinct impact on the cumulative survival.

Le travail de thèse s’inscrit dans la problématique très actuelle des mortalités massives de naissain et de juvéniles d’huîtres creuses, C. gigas, et des questionnements autour de l’implication des pesticides dans ce phénomène. La première partie de la thèse a été consacrée à l’étude des effets de pesticides sur les capacités hémocytaires de l’huître creuse (in vitro et in vivo). L’effet immuno-modulateur des xénobiotiques sélectionnés (seul ou en mélange) a été exploré principalement au travers de la cytométrie en flux. La deuxième partie de la thèse a concerné l’étude des effets d’un mélange de pesticides sélectionnés sur le virus OsHV-1 et l’infection qu’il induit chez l’huître creuse. Les effets des pesticides sur le virus lui-même ont été évalués. Les expériences réalisées n'ont pas permis de mettre en évidence, dans les conditions testées, de dégradation des particules virales en présence des polluants. D’autre part, leurs effets sur les huîtres elles-mêmes ont été explorés après traitement des animaux avec un mélange de pesticides lors d’essais de pathologie expérimentale. Il a ainsi pu être montré que des huîtres préalablement contaminées par un mélange de pesticides à des concentrations retrouvées dans l’environnement semblaient être plus sensibles à l’infection virale. La troisième partie de la thèse a concerné l’étude de l’autophagie chez l’huître creuse, C. gigas. La publication du génome complet de cette espèce en 2012 a ouvert de nouvelles possibilités pour étudier l'immunité innée. L’étude de l’autophagie réalisée pour la première fois chez l’huître creuse a consisté lors d’une première étape en la recherche in silico de gènes impliqués dans cette voie et des protéines correspondantes par western blotting. Puis, le rôle de ce processus important dans l’immunité innée a été exploré au travers d’essais de reproduction d’infections en présence ou non de modulateurs de l’autophagie. Les résultats obtenus semblent montrer que l’autophagie soit un processus important pouvant être impliqué dans les capacités de défense de l’huître creuse vis-à-vis d’infections virales et bactériennesThe thesis work is part of the very current issue on mass mortality outbreaks affecting Pacific oyster, C. gigas, spat and juveniles and questions about the involvement of pesticides in this phenomenon. The first part of this thesis was devoted to study the effects of pesticides on hemocyte parameters in the Pacific oyster (in vitro and in vivo). The immunomodulator effect of selected pesticides (alone or in mixture) has been explored principally through flow cytometry. The second part concerned the study of the effects of a pesticides mixture on OsHV-1 itself. No direct effects have been reported on the viral particles in presence of the pollutants. Moreover, pesticide effects on Pacific oysters were also explored through experimental pathology assays after treatment of animals with a polluant mixture. Results showed that pesticide treated oysters appeared more susceptible to the viral infection in experimental conditions. The third part concerned the study of autophagy in the Pacific oyster, C. gigas. The publication of the complete genome in 2012 has opened up new possibilities for the study of innate immunity in this species. The study of autophagy for the first time in oysters consisted in a first step in the in silico search for genes involved in this pathway and the corresponding proteins by Western blotting. Then, the role of this important process in innate immunity has been explored through reproduction infections tests with or without modulators of autophagy. Results showed that autophagy appeared as involved in defence mechanisms against viral and bacterial infection in Pacific oysters

In a period of expansion of oysters farming in Italy, the present work aimed to contribute to this challenge approaching several important aspects connected with oyster health management. Firstly, we evidenced the presence of natural populations of C. gigas along the Italian coasts and showed differences in the distribution and density population between Adriatic and Tyrrhenian Sea. The presence of OsHV-1 infecting these wild populations was detected in all the Adriatic beds, demonstrating high diversity of genotypes, and showing that these individuals may play a role as reservoir of infection in farmed stocks allocated in the same sites. No other potential reservoir hosts have been evidenced during the investigation conducted in other mollusc species. The obtainment of the complete sequence of OsHV-1 µVar genome represents a significant goal reached during the present work. In particular, this result will permit the exploration of virulence factor in future, a better use of transcriptomics, and the development of new specific diagnostic tools.The complete comprehension of the mechanisms at the origin of the mortality events, observed during the two-year survey, is arduous but the study allowed to observe and obtain highly useful information on oyster mortalities and associated pathogens, specifically in the Italian context. In particular, the impact of V. aestuarianus seems to be relevant in some areas.A potential new pathogen for adult oysters, a Tenacibaculum strain, has been decribed.

Depuis 2008, la mortalité des naissains d'huîtres Pacifique Crassostrea gigas est principalement liée au virus de l’ostreid herpesvirus 1 µvariant (OsHV-1 µVar). Les paramètres environnementaux favorisant la persistance et la diffusion du virus pourraient jouer sur sa dynamique de propagation. Les objectifs de cette thèse étaient d’étudier in situ les interactions entre les naissains d’huîtres et leur environnement benthique lors d’un épisode de surmortalité. La photobiologie du microphytobenthos sous les tables semblait en meilleur état comparé à celle observée dans les allées pouvant favoriser la résilience virale. Les tables à huîtres atténuaient la lumière, la température et la dessication évitant ainsi une thermo et photoinhibition du microphytobenthos. Les indices de la qualité environnementale de l’habitat benthique basés sur la communauté macrozoobenthique ont traduit une dégradation du milieu suite aux apports de matière organique induits par les mortalités de naissains d’huîtres puis des échouages des macroalgues. Une quantité importante d’OsHV-1 était retrouvée à la surface du biofilm avant les mortalités. Sa remise en suspension était préférentiellement associée aux particules microphytobenthiques avec de faibles courantsSince 2008, the mortality of Pacific oyster spat Crassostrea gigas has mainly been linked to the Ostreid herpesvirus 1 μvariant (OsHV-1 μVar). Environmental parameters favoring the persistence and spread of the virus could affect its propagation dynamics. The objectives of this thesis were to study in situ the interactions between oyster spat and their benthic environment during an episode of mortality. The photobiology of the microphytobenthos beneath the tables seemed to be in a better state compared to that observed in aisles that could promote viral resilience. The oyster tables attenuated light, temperature and desiccation, thus avoiding thermo and photoinhibition of the microphytobenthos. The benthic habitat environmental quality indices based on the macrozoobenthic community showed a degradation of the environment following the influx of organic matter induced by oyster spat mortalities and strandings of the macroalgae. A significant amount of OsHV-1 was found on the surface of the biofilm before the mortalities. Resuspension was preferentially associated with microphytobenthic particles with small currents

Phylum Mollusca is a large and diverse group of invertebrate protostomes of over 85,000 species including gastropods, cephalopods and bivalves. Molluscs are the largest marine phylum. Marine molluscs are economically important as a high protein food source for humans and provide ecosystem services including nutrient recycling, carbon sequestration, sediment stabilisation and bioturbation. Molluscs are harvested by traditional fishing but are increasingly cultured in many coastal communities worldwide. Hence most information on pathogens and disease is known in molluscs of commercial significance. Bivalves (oysters, mussels, clams, scallops, cockles) are susceptible to a wide range of diseases caused by viruses (e.g. ostreid herpes virus-1 and variants) bacteria (e.g. Vibrio spp., Nocardia crassostreae, Roseovarius spp., rickettsia and Mycobacterium spp.), microsporidians (e.g. Steinhausia spp.), paramyxids (Marteilia refringens and M. pararefringens), haplosporidans (e.g. Haplosporidium nelsoni, Minchinia spp., and Bonamia ostreae) and macroparasites (e.g. trematodes, copepods and nematodes). The gastropod abalone are susceptible to viruses (e.g. Abalone Viral Ganglioneuritis) and bacteria (Rickettsiales-like organism). Of particular importance is Pacific oyster mortality syndrome (POMS) that is polymicrobial in nature with initial infection by ostreid herpesvirus with subsequent bacterial infections by a variety of vibrios, and marteiliosis. In North America, since the early 1950’s there have been episodes of diseases including Dermo disease, caused by Perkinsus marinus, and MSX disease caused by H. nelson in Crassostrea spp. Globally, it is recognised that marine diseases including those that impact molluscs are becoming more frequent and severe due to climate change, in particular increasing seawater temperature, and human activities.

The lyrical works of Czech composers from the end of the 19th century and the beginning of the 20th century are very little known, and not just to Romanian musicians. Even when it comes to composers who have gained notoriety, such as Bedřich Smetana, Antonín Dvořák or Leoš Janáček, without consulting a dictionary, we cannot name more than one of their titles: Smetana’s Prodaná nevěsta, Dvořák’s Rusalka and Janáček’s Jenůfa, even though each of them wrote countless other works dedicated to the opera. When we think of composers like Zdeněk Fibich and Otakar Ostrčil, obscurity is almost total. Beyond the fact that this study attempts to make a contribution to the knowledge in this field, other objectives include analyzing the compositional language that two composers embraced in homonymous operas and observing the manner in which they related to the mythology of their people. One of the major characters of the Czech national mythology is called Šárka, a title that both Leoš Janáček and Zdeněk Fibich have attributed to one of their operas. In studying the action of the two stage works, this research also turns to the Czech writers of that period and the manner in which they reflected the fundamental Czech myths in their literary works. Details related to the time of appearance of the operas and, in the case of Zdeněk Fibich, brief but welcome information on his biography and creation are also presented. The original contribution of this study consists in analyzing the overtures of the two homonymous operas in terms of compositional techniques, elements of construction and musical expression and, last but not least, observing the similarities and differences of vision between the two creators.
