Donald Zeyl's translation of Timaeus meets the highest standard of clarity and naturalness in English while achieving fidelity to the Greek. This new edition introduces contemporary readers to Timaeus by combining in one volume Zeyl's masterful translation and his long introductory essay of circa one hundred pages which situates the dialogue in the development of Greek science, discusses long-standing and current issues of interpretation, and gives an assessment of the role of Timaeus in the history of Western thought. Notes are provided to elucidate difficult passages. Includes an analytic table of contents and a select bibliography.
