Selected from the vast output on the history of historiography produced by Arnaldo Momigliano (1908-1987), these nineteen essays, many translated into English for the first time, contain some of his most profound thoughts about history and historical method. More than a biographer, Momigliano approached his subjects as forces in intellectual history. What made great historians worthy of admiration, he felt, was their promotion of erudition and their commitment to research. While his subjects are as diverse a group as one could imagine, they are united by a shared commitment to searching for the truth about the past.
