A critical and comparative study of Beroul's Tristran

This thesis is a study of Boreal's version of the Tristan legend. Its aim is a better understanding of the romance through an examination of the work itself and of those versions of the legend with which it is associated. Part One of the thesis begins with a survey of the manuscript and of the various editions and goes on to suggest the policy that might be adopted when a more reliable text is sought. (The three appendices are also concerned with textual problems.) There then follow - a review of Tristan scholarship and an appraisal of the relationship between the various representatives of the legend. Beroul's romance is seen as an independent derivative of a lost work and as an influence upon the Folie Tristan of Berne. In Part Two, each of the episodes in Beroul's work is examined. If an episode is also found in other versions, the parallel accounts are scrutinized and emphasis is laid upon those elements which are found to be quite peculiar to our romance. Those episodes in the romance which have no equivalent elsewhere are also examined and suggestions are made as to their possible provenance. At the same time, the structure of the romance is compared with that of other versions. Beroul emerges as a writer who has on occasion re-ordered inherited episodes, in order to present more clearly his own conception of the legend. In the Conclusion, the significance of the parallel versions is ascertained, before Beroul's own conception of the legend is determined. Beroul consistently presents Tristan and Iseut as guilty sinners, but who are yet never beyond redemption, and he draws on theological support in order to suggest that by the end of the romance they are set on the road to salvation

A low temperature X-ray single-crystal diffraction and polarised infra-red study of epidote

The effects of low-temperature on the crystal structure of a natural epidote [Ca1.925Fe0.745Al2.265Ti0.004 Si3.037O12(OH), a = 8.8924(7), b = 5.6214(3), c = 10.1547(6) angstrom and beta = 115.396(8)degrees at room conditions, Sp. Gr. P2(1)/m] have been investigated with a series of structure refinements down to 100 K on the basis of X-ray single-crystal diffraction data. The reflection conditions confirm that the space group is maintained within the T-range investigated. Structural refinements at all temperatures show the presence of Fe3+ at the octahedral M(3) site only [%Fe(M3) = 70.6(4)% at 295 K]. Only one independent proton site was located and two possible H-bonds occur, with O(10) as donor and O(4) and O(2) as acceptors. The H-bonding scheme is maintained down to 100 K and is supported by single crystal room-T polarised FTIR data. FTIR Spectra over the region 4,000-2,500 cm(-1) are dominated by the presence of a strongly pleochroic absorption feature which can be assigned to protonation of O(10)-O(4). Previously unobserved splitting of this absorption features is consistent with a NNN influence due to the presence of Al and Fe3+ on the nearby M(3) site. An additional relatively minor absorption feature in FTIR spectra can be tentatively assigned to protonation of O(10)-O(2). Low-T does not affect significantly the tetrahedral and octahedral bond distances and angles, even when distances are corrected for "rigid body motions". A more significant effect is observed for the bond distances of the distorted Ca(1)- and Ca(2)-polyhedra, especially when corrected for "non-correlated motion". The main low-T effect is observed on the vibrational regime of the atomic sites, and in particular for the two Ca-sites. A significant reduction of the magnitude of the thermal displacement ellipsoids, with a variation of U-eq (defined as one-third of the trace of the orthogonalised U-ij tensor) by similar to 40% is observed for the Ca-sites between 295 and 100 K. Within the same T-range, the U-eq of the octahedral and oxygen sites decrease similarly by similar to 35%, whereas those of the tetrahedral cations by similar to 22%
