No one will dispute the brilliance of the author; few, if any, would have contemplated such a task, or done it better ... H.'s commentary is of enormous value, and will very likely last as long a Gomme's commentary, if not longer, as a primary point of reference for any serious endeavour to understand individual Thucydidean passages, as well as in this volume offering a valuable methodological approach that will give continuing impetus to further analysis ... for years to come, we will all turn to H. when we want to understand more about Thucydides, and much else besides.
Christopher Smith, The Classical Review
The commentary offers many valuable insights and observations... scholars and students will consult HJ. with profit.
Robin Seager. Journal of Hellenistic Studies 119 1999.
Few, if any, can be more knowledgeable or versatile: every page pollulates with original, apposite and enlightening comments and ideas. No teacher of Thucydides or Greek history can afford to be without this book to hand. H's productive capacity and up-to-date mastery of the field is phenomenal ... school teachers have every reason to be indebted to him.
