This edition of Books IV to VII of Diophantus' Arithmetica, which are extant only in a recently discovered Arabic translation, is the outgrowth of a doctoral dissertation submitted to the Brown University Department of the History of Mathematics in May 1975. Early in 1973, my thesis adviser, Gerald Toomer, learned of the existence of this manuscript in A. Gulchln-i Macanl's just-published catalogue of the mathematical manuscripts in the Mashhad Shrine Library, and secured a photographic copy of it. In Sep tember 1973, he proposed that the study of it be the subject of my dissertation. Since limitations of time compelled us to decide on priorities, the first objective was to establish a critical text and to translate it. For this reason, the Arabic text and the English translation appear here virtually as they did in my thesis. Major changes, however, are found in the mathematical com mentary and, even more so, in the Arabic index. The discussion of Greek and Arabic interpolations is entirely new, as is the reconstruction of the history of the Arithmetica from Diophantine to Arabic times. It is with the deepest gratitude that I acknowledge my great debt to Gerald Toomer for his constant encouragement and invaluable assistance.

Herodotus, the great Greek historian, wrote this famous history of warfare between the Greeks and the Persians in a delightful style. Herodotus portrays the dispute as one between the forces of slavery on the one hand and freedom on the other. This work covers the rise of the Persian influence and a history of the Persian empire, a description and history of Egypt, and a long digression on the landscape and traditions of Scythia. Because of the comprehensiveness of this work, it was considered the founding work of history in Western literature. A must-have for history enthusiasts.

Sebastiano Serlio was the most important architectural writer and theorist of the sixteenth century. The author of the first wide-ranging illustrated book on architecture, he produced a complete set of model designs as well as practical solutions for everyday design problems. This volume, the second in a two-volume series of Serlio's entire works, presents the previously unpublished sixth book, the seventh book, and, as well as The Extraordinary Book of Doors, his little-known Castrametation of the Romans, each of which demonstrates Serlio's sophisticated design theories. This is the first translation of Serlio's later works and the first time that the long lost sixth volume has been united with its companion works and restored to its intended position. The book also includes an introduction and notes by translators Vaughan Hart and Peter Hicks that demonstrate Serlio's significance within the history of architecture and the importance of these neglected texts to our understanding of Serlio's work.

Book VII in the "King of the Trees" series. Who creates the clouds and brings the rain? Ravaging the drought-stricken world of Lucambra, camouflaged dragons have trapped Prince Elwyn and the royal family inside their tower. Hope is dwindling when Elwyn unearths an ancient urn containing a cloud-riddle and a three-pronged staff, the keys to a long-lost treasure and clues to Lucambra’s plight. Fending off foggy foes bent on stealing the staff, Elwyn joins forces with a princess scarred by her dark past. Together, they set out to find the treasure and its rightful owner, Cumulon the Cloud King. In the end, they discover both peril and bliss beneath the Birthing Tree. The Birthing Tree portrays Gaelathane’s perfect love as He molds the lives of a prince and princess into one.

These ardent, even obsessed, poems about erotic passion are among the brightest jewels in the crown of Latin literature. Written by Propertius, Rome's greatest poet of love, who was born around 50 b.c., a contemporary of Ovid, these elegies tell of Propertius' tormented relationship with a woman he calls "Cynthia." Their connection was sometimes blissful, more often agonizing, but as the poet came to recognize, it went beyond pride or shame to become the defining event of his life. Whether or not it was Propertius' explicit intention, these elegies extend our ideas of desire, and of the human condition itself.

Oresme's commentary is one of the most relevant documents of the discussions at Paris University in the midst of the 14th Century. Original solutions concerning the main philosophical issues are associated with sharp criticism of the realist and nominalist positions.

With the publication of this book I discharge a debt which our era has long owed to the memory of a great mathematician of antiquity: to pub lish the /llost books" of the Conics of Apollonius in the form which is the closest we have to the original, the Arabic version of the Banu Musil. Un til now this has been accessible only in Halley's Latin translation of 1710 (and translations into other languages entirely dependent on that). While I yield to none in my admiration for Halley's edition of the Conics, it is far from satisfying the requirements of modern scholarship. In particular, it does not contain the Arabic text. I hope that the present edition will not only remedy those deficiencies, but will also serve as a foundation for the study of the influence of the Conics in the medieval Islamic world. I acknowledge with gratitude the help of a number of institutions and people. The John Simon Guggenheim Memorial Foundation, by the award of one of its Fellowships for 1985-86, enabled me to devote an unbroken year to this project, and to consult essential material in the Bodleian Li brary, Oxford, and the Bibliotheque Nationale, Paris. Corpus Christi Col lege, Cambridge, appointed me to a Visiting Fellowship in Trinity Term, 1988, which allowed me to make good use of the rich resources of both the University Library, Cambridge, and the Bodleian Library.
