Erasmus of Rotterdam came from an obscure background and through remarkable perseverance, skill, and vision became a powerful intellectual figure in Europe in the early sixteenth century. He was known for his vigorous opposition to war, intolerance and hypocrisy, and at the same time for an irony and subtlety that could confuse his friends as well as his opponents. His ideas influenced the rise of the Reformation and had a huge impact on the humanities, and that continues to today. This book shows how an independent textual scholar was able, by the power of the printing press and his own wits, to attain both fame and notoriety. Erasmus of Rotterdam is the first popular biography in English in twenty years and is based on the immense amount of recent scholarship devoted to Erasmus.

The fundamental idea of geometry is that of symmetry. With that principle as the starting point, Barker and Howe begin an insightful and rewarding study of Euclidean geometry. The primary focus of the book is on transformations of the plane. The transformational point of view provides both a path for deeper understanding of traditional synthetic geometry and tools for providing proofs that spring from a consistent point of view. As a result, proofs become more comprehensible, as techniques can be used and reused in similar settings. The approach to the material is very concrete, with complete explanations of all the important ideas, including foundational background. The discussions of the nine-point circle and wallpaper groups are particular examples of how the strength of the transformational point of view and the care of the authors' exposition combine to give a remarkable presentation of topics in geometry. This text is for a one-semester undergraduate course on geometry. It is richly illustrated and contains hundreds of exercises.

The history of seventeenth century England was tumultuous. During this period England underwent a civil war, a regicide, an experiment with republican government, a restoration of monarchy and constant upheavals in politics and religion. What a confusing period! As the century began Puritans were poised against Episcopalians, parliament against the forces of an absolutist monarchy and the question hung in the air - what kind of Christian expression would be the Church of England eventually reflect?
