A Raphael Madonna and Child Oil Painting:  A Forensic Analytical Evaluation

A Raphael Madonna and Child Oil Painting: A Forensic Analytical Evaluation

Howell G. M. Edwards

Springer International Publishing AG
2024
sidottu
This book presents a comprehensive forensic analysis of an oil painting depicting a Madonna and Child in a tondo format, previously thought to be a Victorian copy. Detailed historical and scientific studies confirm that this painting was, in fact, created by Raphael around 1512 as a study for his renowned Sistine Madonna, commissioned by Pope Julius II as an altarpiece for the monastic church of San Sisto in Piacenza. The painting underwent rigorous forensic examination, combining historical research with both invasive and non-invasive scientific imaging techniques. The analysis utilized advanced physical and chemical instrumentation to determine the painting's authenticity and accurate chronological placement. A comparative review of published chemical analyses of pigments, dyes, and substrates used in Raphael’s works from collections worldwide is included. Additionally, this study explores the innovative use of artificial intelligence (AI) for facial comparison between the figures in the tondo painting, the Sistine Madonna, and other Raphael artworks. These AI-generated insights provide novel information about the identities of Raphael’s models and shed light on his working techniques, as well as those of his associates.

Blue by Fire: A Marker of the Technical History of Glass and Ceramics

The use of natural mineral and synthetic blue pigments in antiquity for wall paintings and illuminated manuscript historiation evolved into the most suitable blue pigments for the decoration of glazed and enamelled wares (ceramics, glass and metal) which required a stability at the high temperatures of the kilns used for glazing and firing. Historic literature is often vague regarding the blue pigments used for this purpose. The generic term “cobalt blue” covers a wide range of pigments that were actually used for the decoration of faience, majolica, stonewares, earthenwares and porcelains. This book addresses the application of elemental and molecular spectroscopic analytical techniques to a range of diverse problems which arise for decorated ceramics, glass and enamels and related artefacts: a history of techniques, provenance and authentication. The text contains an introduction to the important analytical techniques that are used in destructive and nondestructive analytical measurements and highlights potential future applications based upon novel miniaturised instrumentation for in-situ studies. The book is co-authored by two international experts with many years’ experience in the application of analysis to artworks and archaeological artefacts and in the investigation of materials and sites for cultural heritage preservation. Among 19 chapters one is devoted to an evaluation of the analytical techniques that are used and the pitfalls which can arise in the interpretation of the data. The approach conveys the detailed information which has become available from the adoption of analytical techniques to diverse problems through the scientific interrogation of ceramic and related artefacts. Examples are given of how the pigment analysis and sourcing can provide unique information about ancient trade routes and pigment sourcing historically. A classic instance is provided by the transfer of European enamelling technologies carried out at the beginning of the 17th century in Japan (Arita) and at the turn of the 17th-18th centuries in China by the Jesuits established at the Court of, respectively, the Kyushu island of Daymios and the Chinese Qing Empero Kangxi. It has hence been demonstrated that some of the most beautiful porcelains emanating from Japan and China in this period incorporate blue decoration with pigments supplied from Europe. The interpretation of the analytical data can assist museum curators, archaeologists, art dealers/experts and cultural heritage historians in the preservation and conservation of ancient materials which have applied blue pigment decoration.

This book describes a holistic study of the porcelain manufactured at Nantgarw and Swansea in the first quarter of the 19th Century, using both scientific analytical data and historical provenancing. This porcelain is acclaimed as some of the finest and most translucent porcelain ever produced. These two porcelain factories are linked through the artistic and creative activities of the enigmatic William Billingsley and had a strictly limited production over only three or four years during the period 1812-1820. The earliest chemical analysis of these porcelains were undertaken almost 100 years ago and are compared with the results of more recent analyses The chemical composition of these porcelains, their artistic decoration and the struggle to maintain quality production is reviewed. Scientific explanations are proposed for the characteristic Swansea duck-egg porcelain translucency and for the Nantgarw iridescence. The book is well illustrated throughout and affords a good basis for the further in-depth study of Swansea and Nantgarw porcelains.

This book gives a detailed account of the holistic research carried out on the analytical data obtained historically on the products of the Nantgarw and Swansea porcelain manufactories which existed for a few years only during the second decade of the 19th Century. A background to the establishment of the two factories, which are linked through the persons of the enigmatic William Billingsley and his kiln manager, Samuel Walker, involves the sourcing of their raw materials and problems associated with the manufacture and distribution of the finished products. A description of the minerals and additives used in porcelain production is recounted to set the scene for the critical evaluation of the comprehensive analytical data which have been published on Nantgarw and Swansea porcelains. For the first time, the author has adopted a nondestructive technique, Raman spectroscopy, to interrogate perfect samples of Nantgarw and Swansea porcelain, as well as a selection of shardsfrom an archaeological excavation carried out at a waste dump at the Nantgarw China Works site. Following these experiments, several questions relating to the porcelain bodies of Swansea and Nantgarw china can be answered and a protocol established for the preliminary evaluation of items of suspect attribution to confirm or not the correctness of their assignment to these Welsh porcelain factories.

The State, France and the Sixteenth Century

The State, France and the Sixteenth Century

Howell A. Lloyd

TAYLOR FRANCIS LTD
2026
sidottu
Originally published in 1983, this book discusses an important ideological development: the emergence of a new concept of the state as a substantive entity and the source of the ruler’s authority over his subjects. It maintains that such a concept emerged in French political thought of the sixteenth century and was promptly assimilated into existing systems of ideas. The book re-interprets numerous aspects of the French kingdom’s social composition, means of government, economic condition and religious experience, both prior to and during the sixteenth century itself. Examining these aspects in the light of modern research, the book provides an original contribution towards understanding political consciousness in a past society: for it adopts a far broader contextual approach than is normally to be found in the works of specialist historians of ideas.
