The Companion assembles a total of twenty chapters in English throughout, which – as explained in more detail in the Introduction by the two editors – are thematically divided into three sections (“parts”): “Isidore’s Contexts” (chapters 1-4, including the “Introduction”), “Themes in Isidore’s Works” (chapters 5-13), and “Transmission andReception of Isidore’s Work and Thought” (chapters 14-20); Isidore’s works and their reception are thus the two focal points of the volume, while the chapters in part 1 are more introductory in character. In what follows, I discuss in more detail a few selected contributions from all three parts, but not without occasionally pointing out cross-connections to other contributions in the volume. I then draw a synoptic conclusion.
