Anno Lucis

Anno Lucis (in the Year of Light) was adopted by Freemasonry sometime in the 18th century. It was taken from the Anno Mundi or "In the Year of the World", which was first implemented in the 17th century by Bishop James Ussher. The masonic date is found by adding 4004 (or the rounded form 4000) onto the current year and this is seen on certificates. Other orders use their own dating system such as the RCC (Anno Ordinis -The Year of our Order (subtracting 312) or the KT (subtracting 1118) as both dates are AD). What was his background and should we still use this woefully in correct figure?

Bishop Ussher lived through momentous times, having been born during the reign ofElizabethand dying, in 1656, under Cromwell. He was a talented fast-track scholar who enteredTrinityCollegeinDublinat 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 theAngloIrishChurchinIreland.

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 himselfto 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.

Although Ussher brought stunning precision to his chronology, Christians for centuries had assumed a history roughly corresponding to his. The Bible itself provides all the information necessary to conclude that Creation occurred less than 5,000 years before the birth of Christ. Shakespeare, in As You Like It, has his character Rosalind say, “The poor world is almost six thousand years old.” Martin Luther, the great reformer, favoured (liking the round number) 4000 B.C. as a date for creation. Astronomer Johannes Kepler concluded that 3992 B.C. was the probable date.

As palaeontologist Stephen Jay Gould points out in an essay on Ussher, the bishop’s calculation of the date of Creation fuelled much ridicule from scientists who pointed to him as “a symbol of ancient and benighted authoritarianism.” Few geology textbook writers resisted taking a satirical swing at Ussher in their introductions. How foolish, the authors suggested, to believe that the earth’s geologic and fossil history could be crammed into 6,000 years. Gould, while not defending the bishop’s chronology, notes that judged by the research traditions and assumptions of his time, Ussher deserves not criticism, but praise for his meticulousness. The questionable premise underlying Ussher’s work, of course, is that the Bible is inerrant.

Ussher began his calculation by adding the ages of the twenty-one generations of people of the Hebrew-derived Old Testament, beginning with Adam and Eve. If the Bible is to be believed, they were an exceptionally longlived lot. Genesis, for example, tells us that “Adam lived 930 years and he died.” Adam’ s great-great-great-great-great-grandson, Methuselah, claimed the longevity record, coming in at 969 years. Healthier living conditions contributed, or so it was believed, to the

long life spans of the early generations of the Bible. Josephus, a Jewish theologian writing in the first century, explained it this way “Their food was fitter for the prolongation of life… and besides, God afforded them a longer lifespan on account of their virtue.”

To calculate the length of time since Creation, knowledge of more than the ages of death of the twenty-one generations was required; one also needed to know the ages of people of each generation at the time the next generation began. Fortunately, the Bible provided that information as well. For example, Genesis says that at the time Adam gave birth to his first son, Seth, he had “lived 130 years. ” Augustine (as might a lot of people) wondered how a 130-year-old man could sire a child. He concluded that “the earth then produced mightier men” and that they reached puberty much later than did people of his own generation.

The Old Testament’s genealogy took Ussher up to the first destruction of theTempleinJerusalemduring the reign of Persian king Nebuchadnezzar. Ussher’s key to precisely dating Creation came from pinning down, by references in non-Christian sources, the precise dates of Nebuchadnezzar ’s reign. He finally found the answer in a list of Babylonian kings produced by the Greek astronomer Ptolemy in the second century. By connecting Greek events to Roman history, Ussher tied the date of Nebuchanezzar ’s death (562 B.C.) to the modern Julian calendar. Once the date of 562 B.C. was calculated, there remained only the simple matter of adding 562 years to the 3,442 years represented by the generations of the Old Testament up to that time: 4004.

Ussher next turned his attention to identifying the precise date of Creation. Like many of his contemporary scholars, he assumed that God would choose to create the world on a date that corresponded with the sun being at one of its four cardinal points—either the winter or summer solstice or the vernal or autumnal equinox. This view sprang from the belief that God had a special interest in mathematical and astronomical harmony. The deciding factor for Ussher came from Genesis. When Adam and Eve found themselves in the Garden of Eden, the fruit was invitingly ripe. Ussher reasoned, therefore, that it must have been harvest time, which corresponded with the autumnal equinox: “I have observed that the Sunday, which in the year [4004 B.C.] aforesaid, came nearest the Autumnal Equinox, by Astronomical Tables, happened upon the 23rd day of the Julian October.”

It is now generally agreed that the earth is 4.54 billion years old which is significant different from Ussher’s estimate. Therefore, should the Craft continue to use this dating system which is wrong or keep it as part tradition?

The year of Light represents the symbolic moment that light came into the world at its creation. As found in Genesis 1:3 KJV, “And God Said,” Let there be light: and there was light.” In the early days of the Grand Lodge of England, when they started using Anno Lucis it was sometimes referred to as in the year of Masonry and so perhaps it makes sense from that point, but the error should be explained to any brother who enquires.
