Joannes Lydus is a book written by Johannes Laurentius Lydus and first published in 1837. The book is a collection of works by the Byzantine historian, Joannes Lydus, who lived in the 6th century AD. It includes his most famous work, ""De Magistratibus"", which provides a detailed account of the Roman imperial bureaucracy and its functions. The book is divided into three parts, with the first part discussing the life and works of Joannes Lydus, the second part containing his writings on Roman bureaucracy, and the third part containing his other works on topics such as astronomy, mythology, and geography. The book is a valuable resource for historians and scholars interested in the history of the Roman Empire and Byzantine culture.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
