Martin Luther posted his Ninety-five Theses on the church door at Wittenberg in 1517. In the three years that followed, Luther clarified and defended his position in numerous writings. Chief among these are the three treatises written in 1520. In these writings Luther tried to frame his ideas in terms that would be comprehensible not only to the clergy but to people from a wide range of backgrounds. To the Christian Nobility of the German Nation is an attack on the corruption of the church and the abuses of its authority, bringing to light many of the underlying reasons for the Reformation. The second treatise, The Babylonian Captivity of the Church, contains Luther's sharp criticism of the sacramental system of the Catholic church. The Freedom of a Christian gives a concise presentation of Luther's position on the doctrine of justification by faith. The translations of these treatises are all taken from the American edition of Luther's Works. This new edition of Three Treatises will continue to be a popular resource for individual study, church school classes, and college and seminary courses.

Includes "Commentariolus," Copernicus' hypotheses for heavenly motions; "Narratio Prima," popular introduction to Copernican theory; and "The Letter Against Werner," refutation of the views of a contemporary. Extensive editorial apparatus.

In AD 726, the Byzantine emperor ordered the destruction of all icons, or religious images, throughout the empire, and icons were subject to an imperial ban that was to last, with a brief remission, until AD 843. A defender of icons, St John of Damascus wrote three treatises against "those who attack the holy images." He differentiates between the veneration of icons, which is a matter of expressing honor, and idolatry, which is offering worship to something other than God.

Threatened on all sides by relentless enemies for a thousand years, the Byzantines needed ready armies and secure borders. To this end, experienced commanders compiled practical handbooks of military strategy. Three such manuals are presented here. The Anonymous Byzantine Treatise on Strategy was written by a retired combat engineer around the middle of the sixth century, while Skirmishing and Campaign Organization and Tactics date from the late tenth century and concern warfare in the mountains along the Syrian frontier and campaigns in the rugged terrain of the Balkans. These treatises provide information not only on tactics and weaponry but also on the motivations of the men who risked their lives to defend the empire.
