This is the first English translation of Thomas Harriot’s seminal Artis Analyticae Praxis, first published in Latin in 1631. It has recently become clear that Harriot's editor substantially rearranged the work, and omitted sections beyond his comprehension. Commentary included with this translation relates to corresponding pages in the manuscript papers, enabling exploration of Harriot's novel and advanced mathematics. This publication provides the basis for a reassessment of the development of algebra.

The history and development of English, from the earliest known writings to its status today as a dominant world language, is a subject of major importance to linguists and historians. In this book, a team of international experts cover the entire recorded history of the English language, outlining its development over fifteen centuries. With an emphasis on more recent periods, every key stage in the history of the language is covered, with full accounts of standardisation, names, the distribution of English in Britain and North America, and its global spread. New historical surveys of the crucial aspects of the language are presented, and historical changes that have affected English are treated as a continuing process, helping to explain the shape of the language today. This complete and up-to-date history of English will be indispensable to all advanced students, scholars and teachers in this prominent field.
