Architrenius is a vivacious and influential Latin satirical poem dating from 1184. It describes the journey of a young man (the "Arch-Weeper") on the threshold of maturity, confronting the ills of the church, court, and schools of late twelfth-century Europe. The directness with which the poem engages social, psychological, and sexual problems anticipates the work of great vernacular writers such as Chaucer. Winthrop Wetherbee's prose translation is presented alongside the original Latin, and augmented by an introduction and extensive notes.

Protists represent an immensely diverse group of organisms comprised of algae, fungi and protozoa. The nature of protistan cell surface is as diverse as the terminology that has evolved to describe the various surface components. This terminology is defined and discussed in the opening of this book. The remaining contributions provide an up-to-date synopsis of structure, development and function of protistan cell surfaces, including their role in taxonomy and systematics.
