The first use of the Latin term anno aerae nostrae vulgaris^[e] discovered so far was in a 1615 book by Johannes Kepler.^[6] Kepler uses it again, as ab Anno vulgaris aerae, in a 1616 table of ephemerides,^[17] and again, as ab anno vulgaris aerae, in 1617.^[18] A 1635 English edition of that book has the title page in English – so far, the earliest-found use of Vulgar Era in English.^[19] A 1701 book edited by John LeClerc includes "Before Christ according to the Vulgar Æra, 6".^[20] A 1716 book in English by Dean Humphrey Prideaux says, "before the beginning of the vulgar æra, by which we now compute the years from his incarnation."^[21][22] A 1796 book uses the term "vulgar era of the nativity".^[23]
