This work illustrates the impact of Greek and Latin texts on the Middle Ages and Renaissance. It furnishes concrete evidence of when, where, andhow an ancient author was known and appreciated in monastic, university, and humanist circles. Each article presents a historical survey of the influence and circulation of a particular author down to the present, followed by a listing and brief description of Latin commentaries before 1600 on each of his works. In this edition, Volume III, six authors are treated in separate articles: Damianus; Geminus Rhodius; Hanno; Sallust; Themistius; and Thucydides. Thucydides and Sallust were major historians. Damianus and Geminus Rhodius influenced optics and astronomy. Themistius provided a useful service to later students of Aristotle by paraphrasing Aristotle's treatises on logic, psychology, and natural science. Hanno's account of a voyage around the coast of West Africa has been regarded as a motivating factor behind the explorations of Vasco da Gama and Pedro Alvares Cabral and was cited in controversies involving the Portuguese and Spanish claims to the coasts of Africa and America.
