The Corpus Iuris Civilis, a distillation of the entire body of Roman law, was directed by the Emperor Justinian and published in a.d. 533. The Institutes, the briefest of the four works that make up the Corpus, is considered to be the cradle of Roman law and remains the best and clearest introduction to the subject. A Companion to Justinian's "Institutes" will assist the modern-day reader of the Institutes, and is specifically intended to accompany the translation by Peter Birks and Grant McLeod, published by Cornell in 1987. The book offers an intelligent and lucid guide to the legal concepts in the Institutes. The essays follow its structure and take up its principal subjects--for example, slavery, marriage, property, and capital and noncapital crimes--and give a thorough account of the law relating to each of them. Throughout, the authors explain technical Latin vocabulary and legal terms.

The Institutes are a complete exposition of the elements of Roman law and are divided into four books—the first treating of persons and the differences of the status they may occupy in the eye of the law; the second-of things, and the modes in which rights over them may be acquired, including the law relating to wills; the third of intestate succession and of obligations; the fourth of actions and their forms. For many centuries they had been the familiar textbook of all students of Roman law.

The book explores the history of Justiniana Prima, a city built by Emperor Justinian I (527-565) in his birthplace near Niš in present-day Serbia. Previous studies focused on determining the city's location, underestimating the significance of analyzing written sources for the reconstruction of this city's genesis and importance. Using information from Emperor Justinian's Novels XI and CXXXI, as well as Book IV of Procopius of Caesarea's De aedificiis, Stanislaw Turlej endeavors to show that Justiniana Prima's historic significance resulted from granting its Church the status of an archbishopric with its own province in 535, which was independent of Rome. Justinian wanted to introduce profound changes to the ecclesiastical organization based on state law.

This book traces the history of Justinian's Institutes, Code, and Digest from late antiquity to the juristic revival of the late eleventh century. It includes extensive discussion of manuscripts and other evidence, and plates of many important manuscripts that have never before been reproduced.
