This is the third of four volumes of the correspondence of Wolfgang Capito (c.1478–1541), the distinguished humanist and Hebraist, and a leading figure in Strasbourg's Reformation (previous volumes appeared in 2005 and 2009). These volumes complement a website (http://www.itergateway.org/capito/) on which are provided the original texts – in Latin and German – from which the translations have been made. It is perhaps surprising that only passing reference to the website is made in a single footnote in this volume. One also has the impression that more might have been done to make the two media work together: not only does the printed volume not indicate which language individual letters had been written in, necessitating reference to the website, but, frustratingly, for those letters for which only a summary is provided in the printed edition (on the grounds that they are available in the published correspondences of other major figures, but presumably also for reasons of space and cost), no further material is provided on the website. Readers without easy access to those other collections, and students lacking the requisite linguistic skills to read the originals, are left with only a partial picture. None the less, this project as a whole is providing a major service to the scholarly community. Rummel's translations are elegant and idiomatic, while Kooistra's annotations are extensive and helpful: each letter is preceded by a – sometimes substantial – headnote, which places it in its historical context, and highlights significant themes, while in the footnotes there is an effort to identify as many individuals, details and textual allusions as possible. This volume covers only five years, but the two hundred or so letters that it contains shed light on a wide range of themes. At the personal level, we see the concern of his friends following the death of his wife, Agnes, in 1531, and his subsequent marriage to Johannes Oecolampadius’ widow, Wibrandis, in 1532. The letters also provide a fascinating running commentary on the Reformation as it developed both in Strasbourg specifically, and in the southern German and Swiss lands more generally, particularly in the wake of the second battle of Kappel, in which Zwingli had lost his life. We see, for instance, Capito and his Strasbourg colleagues providing advice to other cities such as Bern and Zurich on practical, theological and political matters, and receiving requests for personnel, to which they were not always willing or able to accede. Disagreements over the eucharist run through these letters with Capito's efforts to find agreement increasingly falling on deaf ears. Equally, the letters reveal the extent to which Capito sought to maintain respect for, and loyalty to, Luther, whom he described as ‘our commander’ in a letter of September 1535 to Johannes Brenz, while the hopes of compromise rapidly dwindled. Capito's efforts, often behind the scenes, at concord emerge very clearly from the letters gathered here. This volume is a real testimony to his important contribution to the Reformation cause.
