Davis was born in Chepstow, Monmouthshire, Wales, and, on 18 February 1723 at the age of sixteen, he matriculated at Jesus College, Oxford.
[1] His work Origines Divisianae, or, The antiquities of the Devizes in some familiar letters to a friend wrote in the years 1750 and 1751 was published in 1754.
It caricatured the antiquarian studies of William Stukeley (who pioneered the archeological investigation of Stonehenge) and his contemporaries, presenting various fancies as facts of local history.
[1] Davis showed his sense of humour with turns of phrase such as: An old woman, who shew'd Lord Bathurst's fine place by Cirencester, was ask'd by a Gentleman that came to see it—Pray what building is that?—Oh Sir, that is a ruin a thousand years old, which my Lord built last year; and he proposes to build one this year half as old again.and finished his book by writing: The foregoing papers were wrote by no man living,—for the Author dy'd some months ago.
He long entertain'd a disrelish for the modern sort of scholarship and was not unwilling for these papers to go to the press to prevent many larger from going there.
