Happy Birthday, Earth

9 a.m. October 23, 4004 B.C. as calculated by Bishop James Ussher in 1650.

When Clarence Darrow prepared his famous examination of William Jennings Bryan in the Scopes trial, he chose to focus primarily on a chronology of Biblical events prepared by a seventeenth-century Irish bishop, James Ussher. American fundamentalists in 1925 found—and generally accepted as accurate—Ussher’s careful calculation of dates, going all the way back to Creation, in the margins of their family Bibles. (In fact, until the 1970s, the Bibles placed in nearly every hotel room by the Gideon Society carried his chronology.) The King James Version of the Bible introduced into evidence by the prosecution in Dayton contained Ussher’s famous chronology, and Bryan more than once would be forced to resort to the bishop’s dates as he tried to respond to Darrow’s questions.

The chronology first appeared in The Annals of the Old Testament, a monumental work first published in London in the summer of 1650. In 1654, Ussher added a part two which took his history through Rome’s destruction of the Temple in Jerusalem in 70 A.D. The project, which produced 2,000 pages in Latin, occupied twenty years of Ussher’s life.

Ussher lived through momentous times, having been born during the reign of Elizabeth and dying, in 1656, under Cromwell. He was a talented fast-track scholar who entered Trinity College in Dublin at the early age of thirteen, became an ordained priest by the age of twenty, and a professor at Trinity by twenty-seven. In 1625, Ussher became the head of the Anglo-Irish Church in Ireland.

As a Protestant bishop in a Catholic land, Ussher’s obsession with providing an accurate Biblical history stemmed from a desire to establish the superiority of the scholarship practiced by the clergy of his reformed faith over that of the Jesuits, the resolutely intellectual Roman Catholic order. (Ussher had absolutely nothing good to say about “papists” and their “superstitious” faith and “erroneous” doctrine.) Ussher committed himself to establishing a date for Creation that could withstand any challenge. He located and studied thousands of ancient books and manuscripts, written in many different languages. By the time of his death, he had amassed a library of over 10,000 volumes.

The date forever tied to Bishop Ussher appears in the first paragraph of the first page of The Annals. Ussher wrote: “In the beginning, God created heaven and earth, which beginning of time, according to this chronology, occurred at the beginning of the night which preceded the 23rd of October in the year 710 of the Julian period.” In the right margin of the page, Ussher computes the date in “Christian” time as 4004 B.C
