Annales Veteris Testamenti, a prima mundi origine deducti, or more commonly known as Annals of the World in its shortened, English translation, is Ussher’s best-known book. Starting with the year 70 AD, Ussher attempted to work backward through the Old Testament to give an account of the world's history, including the date of its creation. A literary feat of dazzling proportions, Ussher’s classic work required extensive language, historical, and biblical knowledge, and a wide-ranging use of sources (which Ussher traveled extensively to find). Presented in its original Latin, Annales Veteris Testamenti is an exciting trove of historical and biblical content, a literary epic far surpassing any other work of its kind during that era.
