Evidence of systematic astronomical observation and the impact of celestial knowledge on culture is plentiful in the Bronze Age societies of Egypt, Mesopotamia and Europe. An interest in astral phenomena is also reflected in Hittite documents, architecture and art. The rock-cut reliefs of 64 deities in the main chamber of Yazilikaya, a Hittite rock sanctuary associated with Hattusa, the Hittite capital in central Anatolia, can be broken into groups marking days, synodic months and solar years. Here, we suggest that the sanctuary in its entirety represents a symbolic image of the cosmos, including its static levels (earth, sky, underworld) and the cyclical processes of renewal and rebirth (day/night, lunar phases, summer/winter). Static levels and celestial cyclicities are emphasised throughout the sanctuary – every single relief relates to this system. We interpret the central panel with the supreme deities, at the far north end of Chamber A, as a reference to the northern stars, the circumpolar realm and the world axis. Chamber B seems to symbolise the netherworld.

AbstractAttention is drawn to an unpublished oil sketch belonging to Mr. Guy Folkner of Brussels (Fig. 11), which is a modello for the signed painting by Thomas Willeboirts Bosschaert (1613/14-54) of Venus Lamenting Over Adonis in Jagdschloss Grunewald near Berlin (Fig. 2, Note 1). Another version, not signed and formerly attributed to Anthony van Dyck, is in the National Gallery of Canada, Ottawa (Fig. 3, Note 2). The pose of Adonis is derived from the figure of Christ in the central panel of Rubens' Descent from the Gross (1611-12) in Antwerp Cathedral (Fig. 4, Note 3) it should be noticed that the left arm of Adonis is a reverse rendering of the right arm of Christ (Fig. 5). However, the figures are treated by Willeboirts in the more elegant style of Van Dyck, the predominant influence on Flemish history painting shorty after 1640 or thereabouts. Two paintings by Willeboirts, ectch representing a different episode in the story of Venus and Adonis, are known to have belonged to the collections of the House of Orange: the Venus Lamenting Over Adonis now at Jagdschloss Crunewald and an Adonis Leaving Venus, formerly in the Mauritshuis in The Hague, which was destroyed by fire in 1940 in Middelburg, where it was on loan (Fig. 6). It is not easy to determine which of the two corresponds with the picture that Willeboirts painted for the Stadholder Frederick Henry in 1642 and which thus belonged to the first, commission received from him (Note 7), since in the documents concerned this is referred to only as Venus and Adonis. However, some characteristics of the painting formerly in the Mauritshuis are to be found in other works by Willeboits dating from 1646 and 1647 (Notes 20- 22) , so that it must have been done at about the same time as these. The painting at Grunewald may represent a somewhat early tage in his artistic evolution and might thus correspond with the one made for Frederick Henry in 1642. The discovery of this modello brings the number of known oil sketches by Willeboirts up to four, of which it is the earliest. The others are: a bozzetto in the Louvre for the large painting of The Princes Maurice and Frederick Henry on Horseback, commissioned by Amalia van Solms in 1649-50 for the Oranjezaal in the Huis ten Bosch (Note 24), a sketch for the large altarpiece of The Immaculata painted for the high altar of the church at Fuensaldana in 1652-4 and now in the Museo Nacional at Valladolid (Note 25), and an oil sketch in the Musée de Picardie at Amiens for The Assumption of the Virgin in the Church of Our Lady at Duffel (Note 26). A fifth sketch, a Venus and Adonis on paper belonging to the Earl of Wemyss (Note 27), proves to be the model for another Adonis Leaving Venus (Fig. 9), attributed to Willeboirts by Ludwig Burchard, which was on the art market in Berlin in 1930 (present whereabouts unknown). Here we see the same type of Venus as in, for example, The Toilet of Venus signed and dated 1644, which probably belonged to the House of Orange (Fig. 10, Note 29) and which came up at an auction in Stockholm in 1981. It seems likely that the paintings which Willeboirts and other Flemish painters made for the court in The Hague exerted some influence on Dutch painters active at the same period. Mythological pieces by Ferdinand Bol (Fig. 12, Note 45), Jacob Backer (Note 50), Caesar van Everdingen (Note 51) and others, in which a 'elassistic' tendency appears after about, 1650, do indeed show a rather similar elegant style and are characterized by the same idyllic mood. However, this is a matter which still requires further study.

AbstractIn the Musée des Beaux-Arts at Lille there are two shutters from a North-Netherlandish commemorative painting (fig. 2/3) which on comparison with two others in the museums at Valenciennes (fig. i) and La Fère may be attributed to the painter Aertgen van Leyden. The coats of arms painted on the outsides of the shutters (fig-4/5) identify the sitters as Claes Alewijn Claeszz., burgomaster of Leiden (d. 1561), and his wife Anna Cornelisdr. van der Hooch (d.1558) with their children. The whereabouts of the central panel are unknown, but the work must have been painted for the Pieterskerk in Leiden, where the same couple's tombstone, made by the Frisian carver Pieter Dircksz., still is (fig. 6).

AbstractThe triptych which has hung above the main altar of Our Lady of the Immaculate Conception at Maria-ter-Heide (Brasschaat, near Antwerp) since the nineteenth century unfolds a highly unusual iconographical programme. The representation on the central panel is a 'Holy Kinship' with Saint Anne; the left and right shutters show a 'Tree of Jesse', and the 'Kinship of Effra and Ismeria' respectively. This unusual combination of themes, and the coat of arms of the abbey at Tongerlo on the staff of the kneeling donor on the left shutter, enable us to identify the triptych from an old description, predating 1615, of the art treasures in the abbey at Tongerlo. As early as 1888 canon Van Spilbeek was able to demonstrate on the basis of two entries in the abbey's ledgers that the retable was made around 1513-1515. It was commissioned by the then abbot of Tongerlo, Antonius Tsgrooten. The painter's name appears on both bills of payment of 1513-1515. He was called Johannes, and he was married to Marie Hoesacker. His apparent lack of a surname might intimate that he was a foundling. Hitherto, the triptych in Maria-ter-Heide was the only known work by 'Johannes'. The author suggests that he also painted the monumental triptych with scenes from the lives of Christ and Mary which has been on loan to the museum at Àvila since 1971 from the Provincial Council. In 1968 Karel G. Boon attributed this work to an anonymous North-Netherlandish painter. According to Boon the same artist painted two wings with John the Baptist and Saint Agnes (Paris, private collection) and a 'Baptism of Christ' (Madrid, private collection). 'Johannes' could be the maker of these three works. What is more, the painter of the triptych in Maria-ter-Heide could be credited with two retable wings which have been in the Museo de Santa Cruz in Toledo since the 19608. Their subjects are 'Saint Andrew with Saint Francis' and 'Saint James with Saint Antony of Padua'; on the back of these panels is a 'Visitation'. Judging by the numerous figures he borrowed from Rogier van der Weyden, 'Johannes' seems to have been fascinated by the great Brussels master. His interest in Van der Weyden's art and the fact that he worked for the abbot of Tongerlo suggest that he was active in Brabant. The Dutch elements which Boon claimed to recognise on the Àvila triptych are quite inconspicuous, proving how dangerous it is to determine an artist's provenance solely on the basis of aesthetic impressions. The iconographic programme on the triptychs in Maria-ter-Heide and Avila and the retable wings in Toledo is highly unusual. This indicates that they were not made for the open market on the painter's own initiative, but were ordered specially. Perhaps 'Johannes' ability to convert such iconographic programmes into pictures was one of the reasons for his success a success which, in view of the presence of two of his works in Castile, assumes an international dimension.

SummaryThe aim was to analyze the degree of agreement between the central review panel and the local PET interpretation within the HD15 trial and its impact on subsequent treatment and progression free survival. Patients, methods: The analysis set consisted of 739 patients with residues ≥ 2.5 cm after 6 or 8 cycles of BEACOPPesc from the HD15 trial performed by the German Hodgkin Study Group. The recommendation for or against further radiotherapy was based on the central [18F]FDG-PET interpretation. Central PET interpretation was compared to the local PET interpretation and concordance was measured using Cohen's Kappa coefficient. Prognostic impact of the analysis of concordance between local and central PET interpretations was evaluated using progression free survival (PFS); groups were compared with the log rank test. Results: The central panel rated 548 of 739 patients (74%) as PET negative. Of these, 513 were also rated as PET negative in the local PET interpretation. PET positivity was seen by central reviewers in the remaining 191 patients (26%), in concordance with local reviewers in 155 cases. Even though substantial agreement was found (Cohen's Kappa 0.81), the interpretation of the central PET review panel led to a different therapeutic recommendation in 71/739 (10%) patients. PFS was equally high in groups in which the therapeutic regime had been changed on the basis of the central panel decision. Conclusion: High concordance is found between local and central reviewers with regard to PET interpretation in residual tissue after intense chemotherapy. The existence of the central PET review panel allows the identification of additional patients as PET negative so that radiotherapy can be safely omitted (35 of 548 patients = 4.7%).

This chapter includes a section of plates in which ceremonial objects are illustrated and documented according to the communities in which they were used. It highlights the plates of textile that typically represent the ceremonial artistic concept of each community. It also describes the wrap from Rome that consists of fourteen pieces of undyed linen of various widths with linen strips that are embroidered with a pattern of vines. The chapter looks at a wrap from Rome that was stored in Museo Ebraico di Roma, which is made of seven pieces of rectangular fabric arranged symmetrically on each side of the central panel, which depicts the giving of the Torah on Mount Sinai. The chapter analyses the embroidery of two pieces of fabric to the right and left of the central panel of the wrap with the name of the donor, Joseph Samuel Sarina.
