This monograph deals with illuminated manuscripts created in French-speaking regions from the mid-thirteenth to the mid-fifteenth century, i.e., from the earliest narratives of Marian miracles written in <?page nr="542"?>Old French to the codices produced at the Burgundian court at the waning of the Middle Ages. Its focus, however, is very specific: it is a systematic analysis of the miniatures depicting both material representations of the Virgin (mainly sculptures, but also icons, panel paintings, altarpieces or reliquaries) and the miracles performed by them, usually as Mary’s reaction to a prayer (or an insult) to one of Her images.

AbstractInfrared (IR) reflectography has been used for many years for the detection of underdrawings on panel paintings. Advances in the fields of IR sensors and optics have impelled the wide spread use of IR reflectography by several recognized Art Museums and specialized laboratories around the World. The transparency or opacity of a painting is the result of a complex combination of the optical properties of the painting pigments and the underdrawing material, as well as the type of illumination source and the sensor characteristics. For this reason, recent researches have been directed towards the study of multispectral approaches that could provide simultaneous and complementary information of an artwork. The present work relies on non−simultaneous multispectral inspection using a set of detectors covering from the ultraviolet to the terahertz spectra. It is observed that underdrawings contrast increases with wavelength up to 1700 nm and, then, gradually decreases. In addition, it is shown that IR thermography, i.e., temperature maps or thermograms, could be used simultaneously as an alternative technique for the detection of underdrawings besides the detection of subsurface defects.

AbstractThe implementation of multidisciplinary research approaches is an essential prerequisite to obtain comprehensive insights into the life and works of the old masters and their timeline in the production of the arts. In this study, traditional art history, cultural heritage, and natural science methods were combined to shed light on an Adoration of the Shepherds painting by Jacques Jordaens (1593–1678), which until now had been considered as a copy. From dendrochronological analysis of the wooden support, it was concluded that the planks in the panel painting were made from Baltic oak trees felled after 1608. An independent dating based on the panel maker’s mark, and the guild’s quality control marks suggests a production period of the panel between 1617 and 1627. Furthermore, the size of the panel corresponds to the dimension known as salvator, which was commonly used for religious paintings during the period 1615 to 1621. Finally, the interpretation of the stylistic elements of the painting suggests that it was made by Jordaens between 1616 and 1618. To conclude, from the synthesis of: (i) dendrochronological analysis, (ii) panel makers’ punch mark and Antwerp Guild brand marks, (iii) re-examination of secondary sources, and (iv) stylistic comparisons to other Jordaens paintings, we suggest that the examined Adoration of the Shepherds should be considered as an original by Jordaens and likely painted in the period 1617–1618. The study is a striking example of the effectiveness of a multidisciplinary approach to investigate panel paintings.

ABSTRACTThe determination of the ambipolar diffusion length, L*, and the effective lifetime, τ*, in p/i and a-Si:H Schottky barriers (ITO/p/a-Si:H/Al-Si; Cr/a-Si:H/Cr/Ag) have been determined by Flying Spot Technique, FST. This technique consists in the transient analysis of the photocurrent/photopotential induced by a laser beam that moves perpendicularly to the structure with a constant motion ratio, at different velocities. Taking into account the competition between the diffusion/drift velocities of the excess carriers and the velocity of the flying spot, it is possible to solve the transport equations and to compute separately L* and τ*, from the asymmetrical distribution responses.
