"Barry O’Halloran has written an important book on the Athenian naval economy that deserves the attention of ancient historians. (...) this is the first to explore the Athenian navy from a political-economic perspective, making it a welcome addition to the recent flurry of work on ancient Greek economic history. (...) O’Halloran is equally comfortable navigating macroeconomic terminology as he is Thucydides’ text. He shows convincingly that the Athenians considered decisions about the navy to be economic decisions. (...) Overall, O’Halloran’s book is compellingly argued, nicely articulated, and well researched. (...) The original watercolors he commissioned to brighten his pages, especially those in Chapter 9 of triremes, shipsheds and Piraeus, are a unique treat and a beautiful touch. (...) O’Halloran’s book is, and will remain, an indispensable resource and reference for anyone interested in Athenian naval or economic history." - Tim Sorg, in: BMCR 2019.09.48
