Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. Early Religious Poetry of Persia by James Hope Moulton was first published in 1911. The text presents an engaging guide to Avestan literature, containing abundant textual quotation and historical information. All poetry is translated into English.
