Calcareous nannofossils assemblages for provenance analysis of European paintings: From the sample preparation to the assemblage comparison
Jaques, Victory Armida Janine ; Holcová, Katarína (advisor) ; Caruso, Francesco (referee) ; Oszczypko-Ciowes, Marta (referee)
This PhD thesis is a commentary of four studies published and a fifth study submitted in peer reviewed and impacted scientific journals. Three studies are methodological work for the preparation of painted micro-samples to improve the measurements accuracy, the samples visualisation, and the combination of measurements methods. The two other papers focus on the fossil assemblages determination and comparison between reference historical areas and original paintings. This work is divided into three main parts, namely the introduction, the methods, and the calcareous nannofossils assemblages. In the introduction, detailed explanations are given about the paintings, historical materials, trade roads, what are nannofossils, how and why to use them. In the methods section, developed preparatory methodologies are summarised, and the most important results are explained. In the third part, the nannofossils assemblages, the differences between the assemblages from different areas in Europe compared to original paintings are explained and correlated to the literature. The impact of the preparatory methods on the results is discussed, and a conclusion is drawn from it in the context of painted artefacts in the Cultural Heritage field are unique, and so are the micro-samples from them. To extract most...

Chemical variability of garnets from the České středohoří Mountains and characterization of their mineral inclusions
Píšová, Barbora ; Skála, Roman (advisor) ; Kotková, Jana (referee)
The samples of garnets used in this study come from clastic sediments from the drillcores Tř-1 and T-31, selected localities of the České středohoří Mountains and garnet-bearing ultramafic rocks sampled by the drillcore T-7. The contents of the major and some minor elements were determined by an electron probe microanalyzer. The garnets from the sediments were divided into 3 groups according to the contents of the end-members: 1) pyrope-, 2) almandine - pyrope- and 3) grosular - almandine-rich. Garnets from the drillcore T-7 were classified according to individual rock types in which they occurred: lherzolite, hazburgite, pyroxenite, eclogite and granulite. Chemical analyzes of garnets displayed the presence of positive correlations Cr vs. Ca vs. Ti Mn in pyrope grains. The contents of trace elements in garnets were studied by an LA-ICP-MS. After normalization to the CI-reservoir, garnets most often show lherzolite profiles of rare earth elements. Garnets of intense red and purple colors show slightly sinusoidal REE profiles. Inclusions enclosed in garnets were studied by a scanning electron microscope. If their dimensions allowed, the major and minor elements were determined by electron microanalysis for inclusions. Inclusions of amphiboles in association with spinel group minerals, carbonates and...

Following old master drawings within the collections of selected Czech collectors
Babická, Lenka ; Zlatohlávek, Martin (advisor) ; Jarošová, Markéta (referee)
Following old master drawings within the collections of selected Czech collectors Abstract This thesis is a contribution to the history of collecting in Bohemia. It deals with the collecting of drawings and tracks them within the selected collections and collectors. It focuses primarily on the old master drawings, defined as works from the 16th to the 18th century. Within the issue of collecting the attention is, even when studying specific personalities, often paid to the picture galleries rather than the print collections. Due to its fragile nature, drawing tends to fit into the background and, if it does not form the main part of the collection, is not reflected. Many of the collections and collectors have come to attention lately, but many still await their appreciation and introduction into new contexts. Keywords Collecting, collector, drawing, Old Master Drawings, Bohemia, provenance, Prokop Toman, Rudolf Kuchynka, Vincenc Kramář, Jan Krčmář, Frits Lugt

Determination of geological provenance by cathodoluminescence spectroscopy of apatites and carbonates
Pánik, Róbert ; Matějka, Dobroslav (advisor) ; Ježek, Josef (referee) ; Skála, Roman (referee)
This work presents new method for determination of geological provenance based on the statistical analysis of cathodoluminescence spectra of marbles and carbonate rocks from various localities in the Bohemian Massif. Analysis is based on the combination of data from seven different measures of spectral similarity and provides results that are more robust than those obtained by approach based only on a single measure of similarity. These results may be further improved by employing meta-analysis that evaluates behaviour of spectra during the individual steps of analysis. Analysis was performed on the original cathodoluminescence spectra, as well as on the residual spectra in which relative variability was amplified by the subtraction of Gaussian trend present in all spectra of carbonates. By combining results from analysis and meta-analysis of both original and residual spectra it was possible to almost unambiguously determine provenance of samples from all studied localities. Agglomerative hierarchical clustering was employed as a supplementary method for classification of spectra. Out of 72 different methods for clustering, one was selected for both original and residual data based on the number of correctly classified spectra. Second part of this work presents analysis of cathodoluminescence...

Ravennate Marble Trade in the Late Antiquity: Material from the San Severo Complex
Tůmová, Helena ; Ondřejová, Iva (advisor) ; Bouzek, Jan (referee) ; Cantini, Federico (referee)
This thesis aims to study the commercial mechanism of Ravenna in the Late Antiquity from the point of view of the amount, type and provenance of the imported stone artefacts (fragments of architectural decoration, revetments slabs, opus sectile, sarcophagi), based on the study of archaeological material from the site of the basilica and the monastery of San Severo in Classe (Ravenna). Ravenna represented an important administrative and cultural center in the 5th and 6th century, connecting western and eastern artistic influences and focusing herself on trade and production. Determination of the stone artefacts from the San Severo locality was principally based on the archaeometric methods and on the combination of archaeologic and geologic approach as well. Specific archaeometric methods (macroscopic, geochemical and mineralogical-petrographic analyses) together with a quantitative evaluation were applied. Many scientific works, dedicated till this time to the art history of late antique Ravenna and dealing also the argument of ravennate "marbles" presumed the prevailing provenance from Proconnesos and usual commercial relations between Ravenna and Constantinople as well. Constantinople played a role of a mediator of oriental localities and Ravenna. The hypothesis concerning the provenance of the...

Use of an X - ray fluorescence analysis for the ceramics of the La Tene period
KREJČÍ, Radim
In my bachelor thesis I try to clarify aspects of the use of an x-ray fluorescence analysis method in the study of a composition of the ceramics and its provenance. I try to gather information about this method, as well as its pluses and minuses, by means of study of domestic and especially international publications and projects dealing with this topic. Knowledge acquired is then used in the research during which I analyse chemical composition of South Bohemian ceramic with graphite admixture from the La Tene period and I try to discover its differences and thanks to that determine potential imports.

The so-called Madonna from Bítov - the Matter of Dating and Stylistic Provenance
BINDER, Jan
The topic of my bachelor´s thesis "So-called Madonna of Bitov - the issue of subsidies and style provenance" is a comparison of the unique sculptural monument with a chosen types of similar Czech and foreign monuments and finding at least a few solutions. The thesis also deals with implanting Madonna into a period, local and even art-historical context. It brings a detailed formal and iconographic description of the work and the author also solves the issue of restoration here.
