James Ussher - Chronology

Chronology

Ussher now concentrated on his research and writing and returned to the study of chronology and the church fathers. After a 1647 work on the origin of the Creeds, Ussher published a treatise on the calendar in 1648. This was a warm-up for his most famous work, the Annales veteris testamenti, a prima mundi origine deducti ("Annals of the Old Testament, deduced from the first origins of the world"), which appeared in 1650, and its continuation, Annalium pars postierior, published in 1654. In this work, he calculated the date of the Creation to have been nightfall preceding 23 October 4004 BC. (Other scholars, such as Cambridge academic, John Lightfoot, calculated their own dates for the Creation.) The time of the Ussher chronology is frequently misquoted as being 9 a.m., noon or 9 p.m. on 23 October. See the related article on the chronology for a discussion of its claims and methodology.

Ussher's work is sometimes associated with Young Earth Creationism, which holds that the universe was created, not billions of years ago, but thousands. But while calculating the date of the Creation is today considered a controversial activity, in Ussher's time such a calculation was still regarded as an important task, one previously attempted by many Post-Reformation scholars, such as Joseph Justus Scaliger and physicist Isaac Newton.

Ussher's chronology represented a considerable feat of scholarship: it demanded great depth of learning in what was then known of ancient history, including the rise of the Persians, Greeks and Romans, as well as expertise in the Bible, biblical languages, astronomy, ancient calendars and chronology, Ussher's account of historical events for which he had multiple sources other than the Bible is usually in close agreement with modern accounts – for example, he placed the death of Alexander in 323 BC and that of Julius Caesar in 44 BC.

But Ussher's last extra-biblical coordinate was the Babylonian king Nebuchadnezzar, and beyond this point he had to rely on other considerations. Faced with inconsistent texts of the Torah, each with a different number of years between Flood and Creation, Ussher chose the Masoretic version. Partly his reasons were sound scholarly ones — the Masoretic text claims an unbroken history of careful transcription stretching back centuries — but his choice was confirmed for him, because it placed Creation exactly four thousand years before 4 BC, the generally accepted date for the birth of Christ; moreover, he calculated, Solomon's temple was completed in the year 3000 from creation, so that there were exactly 1000 years from the temple to Christ, who was the fulfilment of the Temple.
