The last, longest and most damaging of the wars fought between East Rome and Sasanian Persia (603-628) brought the classical phase of west Eurasian history to a dramatic close. Despite its evident significance, not least as the distant setting for Muhammad's prophetic mission, this last great war of antiquity attracted comparatively little scholarly attention until the last decades of the twentieth century. James Howard-Johnston's contributions to the subject, most of which were published in out-of-the-way places (one, that on al-Tabari, is printed for the first time), are brought together in convenient form in this volume. They strive to root history in close observation of landscape and monuments as well as careful analysis of texts. They explore the evolving balance of power between the two empires, look at events through Roman, Armenian and Arab eyes, and home in on the climax of the final conflict in the 620s.
