The main objective of this volume is highly innovative and stimulating... Hicks' essay is a very accurate study of Harmony in the Medieval Platonic Cosmos, and is going to become a must for future researchers in a field that includes a number of disciplines with different epistemological statutes. * Letterio Mauro, Universita di Genova, Greek and Roman Musical Studies * written from a multidisciplinary perspective that includes musicology, philosophy, and history of science ... the inspiration Hicks's book provides to reflect on the place of music in historical and contemporary ways of world-making. * Jacomien Prins, Isis * Composing the World is itself well-composed - its chapters flow, despite their many long citations from the works under discussion. As the book is very much about these texts, most readers will be glad of this florilegium ... Hicks has done a wonderful job of making a complex subject and its somewhat forbidding texts accessible and of drawing out their importance and relevance to manifold wider concerns. * Speculum * Andrew Hicks has been so bold as to add a new book about world harmony, the music of the spheres, and the medieval reception of the Pythagorean concept of a creation organised according to musical principles to the already existing wealth of scholarship ... Hicks has chosen an approach which is new and refreshing, and which goes far beyond the boundaries of what already exists on the subject. * Plainsong & Medieval Music * Andrew H's Composing the World is a well-written and informative work. It was undoubtedly a courageous and imaginative decision to embark on a study of the notion of cosmic harmony in twelfth-century Latin sources, since a successful outcome could only be achieved by someone who combines many skills including not only musicology but medieval Latin philology and paleography, not without some acquaintance with the histories of philosophy and science ... Andrew
H. is obviously a person of great intelligence and already of considerable learning. It seems to me that with his range of expertise he is adding greatly, and could presumably so add in the future, to medieval musicology and medieval studies more generally. * Mittellateinisches Jahrbuch * This ambitious book opens a new window onto twelfth-century philosophical thought, and successfully shows how deeply Platonic conceptions of harmony were embedded within it. As well as becoming essential reading for medievalists who want to develop their knowledge of speculative music theory, it is also worth the attention of early modernists and scholars who focus on present-day philosophical and scientific thought. * British Journal for the History of Science * Hicks writes towards the beginning of his book that, if we neglect the natural philosophers of the twelfth century, 'we have done ourselves and the discipline of musicology a grand disservice' (p. 8). By bringing a musicological perspective to his engagement with these natural philosophers, he enriches our understanding of the twelfth century's musical speculation and raises new questions that broaden musicology itself. * Music and Letters * There is no other work on this topic that can compare in terms of depth, scope, and complexity. This book is likely to become an indispensable point of reference for the study of both medieval musical theory and the school of Chartres. * Bryn Mawr Classical Review * fascinating insights into the way the medieval mind worked as it tried to develop the notion of "a cosmos animated and choreographed according to a specifically musical aesthetic". * Andrew Benson-Wilson, Early Music Reviews *
