Cotton Mather's synoptic commentary on Ezra through the Psalms contains the core of the massive theological and scholarly endeavor that he called Biblia Americana. Here, he links biblical to secular history, analyzes the problem of suffering and evil in creation, and considers the Psalms both as Hebrew poetry and as Christian prophecy. In his annotations on Ezra, Nehemiah, and Esther, Mather explores topics that range from the philosophical underpinnings of international law to court customs in the Persian Empire to the uneven progress of the reformations attempted by Ezra and Nehemiah. In Job, Mather turns to questions of theodicy and natural philosophy. The Psalms commentary shows his linguistic acumen and his formidable skill as a Christian Hebraist, as well as his sensitivity to difficult matters of hermeneutics. Throughout, he displays the lively wit, curious intellect, and compassionate nature that made him one of the most popular ministers of the colonial period.
