John Geometres (10th century) is a key figure in the history of Byzantine poetry. His poems were first published in 1841 by J.A. Cramer, whose edition is based on a single manuscript and contains a large number of inaccuracies. Nonetheless, all the subsequent editors of John Geometres' poems have used this edition without consulting the manuscript(s) themselves. This book presents a new edition of his poems in hexameters and elegiacs, with critical apparatus, commentary and translation. It is a reference book not only for scholars of Byzantine literature, but also for historians and art historians of the Middle Byzantine period, enabling them to arrive at a better formed judgement of the poet and the cultural history of his time. à la mémoire de mon père, Scato, et à ma mère, Marijke

As an introduction to fundamental geometric concepts and tools needed for solving problems of a geometric nature using a computer, this book fills the gap between standard geometry books, which are primarily theoretical, and applied books on computer graphics, computer vision, or robotics that do not cover the underlying geometric concepts in detail. Gallier offers an introduction to affine, projective, computational, and Euclidean geometry, basics of differential geometry and Lie groups, and explores many of the practical applications of geometry. Some of these include computer vision, efficient communication, error correcting codes, cryptography, motion interpolation, and robot kinematics. This comprehensive text covers most of the geometric background needed for conducting research in computer graphics, geometric modeling, computer vision, and robotics and as such will be of interest to a wide audience including computer scientists, mathematicians, and engineers.

In twelfth-century Byzantium, poetry played a key part in various contexts of textual production and consumption. One of the leading poets of this period was Theodoros Prodromos, whose surviving corpus comprises approximately 17,000 verses. Even though most of his poetry has been presented in modern critical editions, a group of his works has been overlooked by modern philologists and literary scholars alike. The selected corpus--conventionally designated as Miscellaneous Poems--consists of texts on various themes and in a wide range of genres, ranging from cycles of religious and secular epigrams to riddles, ethopoiiai, and works of a self-referential and essayistic nature. This book includes the first critical edition and study of these poems, accompanied by English translations and commentaries. Their study contributes to a more nuanced picture of Prodromos' intellectual profile, expanding his image as the 'poet laureate' of the Komnenian court and providing entirely new insights into his activity in the different settings of Constantinopolitan intellectual life. The book also sheds new light on the complex relationship between patronage and other aspects of literary activity and the circulation of the same text in different performative contexts.

Volume I of this 2-volume textbook provides a lively and readable presentation of large parts of classical geometry. For each topic the author presents an esthetically pleasing and easily stated theorem - although the proof may be difficult and concealed. The mathematical text is illustrated with figures, open problems and references to modern literature, providing a unified reference to geometry in the full breadth of its subfields and ramifications.
