The Sacred Books of the East, a 50-volume series, encompasses the seven non-Christian religions of Asia: Hinduism, Buddhism, Taoism, Confucianism, Zoroastrianism, Jainism, and Islam. Translated into English by authorities in their respective fields, these sacred texts have been edited by F. Max Muller and have profoundly influenced civilization. The Zend-Avesta, Part 3 (1887) translated by L. H. Mills, is Volume XXXI of The Sacred Books of the East, a series available from Cosimo Classics. This book, in three parts, focuses on Zoroastrianism. Part 3 contains Yasna, the main liturgical text of Zoroastrianism, dating back to the religion's earliest period and is still used today. This is an excellent addition to the personal library of anyone interested in Zoroastrianism. L. H. MILLS (1837-1918) was born in New York City and attended NYU before becoming Professor of Zend Philology at Oxford University. An authority on the Avestan language, Mills translated The Zend-Avesta, Part 3 (1887). F. MAX MÜLLER (1823-1900) was a German author and orientalist who lived in England most of his life. As a professor at Oxford, he combined the studies of language, culture, and religion to create the discipline of comparative mythology. His body of work included The Sacred Books of the East, which he had edited.
