New archaeological and papyrological discoveries in the Egyptian desert are destined to impact the study of religion in late antiquity. This extended review of An Oasis City (2015) will highlight some of most important findings related to the religious diversity of the region. The tremendous wealth of the new discoveries offers insight into the development of religion during the later Roman Empire. Building on this archaeological overview of Amheida (ancient Trimithis in the Dakhleh Oasis), this paper discusses the local situation of Egyptian religion, Christianity, and Manichaeism in late antiquity, with a particular focus on religious diversity and interaction in everyday life.

This book examines the impact of the discovery of physical evidence for Roman Britain between the late sixteenth and the early twentieth centuries. My earlier work, Roman Officers and English Gentlemen, explored how the Roman past of Britain was articulated as an aspect of ‘imperial discourse’ in British late Victorian and Edwardian society, how the Roman history and monuments of Britain were used to construct an imperial ancestry for contemporary Britain. The Roman empire, and Roman Britain in particular, were drawn upon to provide powerful contrasts and comparisons between the superpowers of their respective ages, drawing out morals and lessons for the contemporary imperial age. This book seeks to address the value of ideas derived from Roman Britain in the construction of British nationhood and in the context of empire-building, but with a far longer chronological perspective. Before the later sixteenth century, people in Britain had thought and written about the Roman past, but conventional wisdom suggests that it is only from this time that a self-critical and conscious appreciation of the classical writings that addressed Britain emerged. It is also from this time that the value of past objects and sites started to be recognized. In studying the ways that objects and remains from the pre-Roman and Roman past were received, we shall see that the increasing comprehension of the significance of ancient objects was itself a result of the gradual acceptance of the authority of the classical texts that referred to pre-Roman and Roman Britain. Knowledge of the culture and history of ancient Britain prior to this time was communicated through a series of mythical tales that presented a heroic picture of the ancient past. For the English, this ‘old British history’ presented what Philip Schwyzer has called a ‘grand and sprawling narrative’, derived mainly from Geoffrey of Monmouth’s Historia Regum Britanniae (The History of the Kings of Britain, c.1136). These powerful ideas related the initial peopling of these islands to Brutus and his followers who had fled the sack of Troy. During medieval times, various associated stories had been elaborated around mythical and semi-mythical ancient rulers of Britain, including Cymbeline and Lear.

The history of ancient decorative wall-painting has yet to be written. The attention of the whole world was attracted by the wonderful discoveries made in Pompeii, and indeed for many years Pompeii stood for ancient decorative wall-painting in general.That Pompeii so completely overshadowed modern ideas on the evolution of this art is due in great measure to the fact that at Pompeii it had found a wonderful exponent and explorer in the late Professor August Mau. His book dealing with the Pompeian decorative mural painting at once became a classic and influenced profoundly text-books and popular works on the history of ancient art and customs.Two facts, however, should be borne in mind. First, that the decoration of Pompeian houses illustrates the art of one epoch. only—the Hellenistic and the earlier Roman Empire, except for a few examples from a still earlier age, and those not before the third century B.C. Also it should be remembered that this art at Pompeii can be taken as characteristic only of Italy and indeed only of Southern Italy; it does not follow that it developed on the same lines in other regions of the ancient world.

Ever since the introduction of glutaraldehyde as a fixative in electron microscopy of biological specimens, the identification of impurities and consequently their effects on biologic ultrastructure have been under investigation. Several reports postulate that the impurities of glutaraldehyde, used as a fixative, are glutaric acid, glutaraldehyde polymer, acrolein and glutaraldoxime.Analysis of commercially available biological or technical grade glutaraldehyde revealed two major impurity components, none of which has been reported. The first compound is a colorless, water-soluble liquid with a boiling point of 42°C at 16 mm. Utilizing Nuclear Magnetic Resonance (NMR) spectroscopic analysis, this compound has been identified to be — dihydro-2-ethoxy 2H-pyran. This impurity component of the glutaraldehyde biological or technical grades has an UV absorption peak at 235nm. The second compound is a white amorphous solid which is insoluble in water and has a melting point of 80-82°C. Initial chemical analysis indicates that this compound is an aldol condensation product(s) of glutaraldehyde.

The aim of this study is to compare methods of sample preparation for elemental analysis. The model system which is used is the human erythrocyte. Energy dispersive spectroscopic analysis has been previously reported for cryofixed and cryosectioned erythrocytes. Such work represents the reference point for this study. The use of plastic embedded samples for elemental analysis has also been documented. The work which is presented here is based on human erythrocytes which have been either chemically fixed and embedded or cryofixed and subsequently processed by a variety of techniques which culminated in plastic embedded samples.Heparinized and washed erythrocytes were prepared by the following methods for this study :(1). Chemical fixation in 4% paraformaldehyde/0.25% glutaraldehyde/0.2 M sucrose in 0.1 M Na cacodylate, pH 7.3 for 30 min, followed by ethanol dehydration, infiltration and embedding in Lowicryl K4M at -20° C.
