A very valuable book. Gabrielsen offers a comprehensive and careful investigation of the trierarchy which goes beyond the reconstruction of fiscals and military realia to place the institution in its social context. Greece and Rome All will appreciate the significance of Gabrielsen's book, for he has demonstrated, more clearly than his predecessors in the study of the trierarchy, the delicate balance between the state and the 'private sector' in this supreme military installation. -- Mark Munn American Historical Review 1996
