Cassiodorus—famed throughout history as one of the great Christian exegetes of antiquity—spent most of his life as a high-ranking public official under the Ostrogothic King Theoderic and his heirs. He produced the Variae, a unique letter collection that gave witness to the sixth-century Mediterranean, as late antiquity gave way to the early middle ages. The Variae represents thirty years of Cassiodorus’s work in civil, legal, and financial administration, revealing his interactions with emperors and kings, bishops and military commanders, private citizens, and even criminals. Thus, the Variae remains among the most important sources for the history of this pivotal period and is an indispensable resource for understanding political and diplomatic culture, economic and legal structure, intellectual heritage, urban landscapes, religious worldview, and the evolution of social relations at all levels of society during the twilight of the late-Roman state. This is the first full translation of this masterwork into English.

A revealing study of the Variae of Cassiodorus and the insight that the epistolary collection can provide into sixth-century Italy.

This book was first published in 2007. Variable stars are those that change brightness. Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, flares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them. This book provides a concise overview of variable stars, including a historical perspective, an introduction to stars in general, the techniques for discovering and studying variable stars, and a description of the main types of variable stars. It ends with short reflections about the connection between the study of variable stars, and research, education, amateur astronomy, and public interest in astronomy. This book is intended for anyone with some background knowledge of astronomy, but is especially suitable for undergraduate students and experienced amateur astronomers who can contribute to our understanding of these important stars.

Periphyton, an algal assemblage which surrounds the submerged parts of higher plants and in some cases covers the bottom like a blanket, is one of the most conspicuous features of South Florida's shallow-water ecoystems--such as found within Everglades National Park. The authors conducted a study of the periphyton in Everglades National Park and the East Everglades 208 study area to: provide a quantitative description of the gross taxonomic composition of periphyton in various aquatic habitats; determine whether statistically significant differences in taxonomic composition between sites can be documented; relate variation in periphyton taxonomic composition to variation in environmental variables; and evaluate the relative potential value of various periphyton taxonomic compositions as a food source.
