Commencing with Adam and the geographical conditions of the first millennium BCE, the author passes to the legendary history of Rome and Babylon, to the accounts of Daniel, Zerubbabel (according to the Apocrypha), the Second Temple, and Cyrus the Great, and to the histories of Alexander the Great and his successors. He then gives the history of the Jews down to the destruction of the Temple. The last part contains, among other things, a brief history of Hannibal and an account of the coronation of an emperor, which, according to Basnage refers to that of Otto the Great (crowned 962); this would be the only and a most valuable source of information concerning this event. If Basnage's conjecture is correct, the date of the composition of the "Yosippon" may be placed at the end of the 10th century. "Yosippon" is written in comparatively pure Biblical Hebrew, shows a predilection for certain Biblical phrases and archaisms, and is rich in poetical passages and in maxims and philosophical speculations. "Yosippon" was much read and was highly respected as a historical source by the Jews of the Middle Ages. Joseph Justus Scaliger in his "Elenchus Trihæresii Nicolai Serarii" was the first to doubt its worth; Jan Drusius (d. 1609) held it to be historically valueless on account of its many chronological mistakes; Zunz and Delitzsch have branded the author as an impostor. In fact, both the manuscripts and printed editions are full of historical errors, misconceptions of its sources, and extravagant outbursts of vanity on the part of the author. But there is scarcely any book in Jewish literature that has undergone more changes at the hands of copyists and compilers; Judah ibn Moskoni knew of no less than four different compilations or abridgments. The later printed editions are one-third larger than the editio princeps of Mantua. It was perhaps due to Jerahmeel ben Solomon that the work received its traditional title "Yosippon." He supplemented his copy from Josephus, whom he designates as "the great Joseph." The original title of the work, according to Trieber, was probably "History of Jerusalem", or, as a manuscript suggests, "History and Wars of the Jews." It is quoted in the Hebrew-Persian dictionary of Solomon ben Samuel (14th century), under the title "History of the Second Temple."
