John (2) Field, son of Richard and Elizabeth Felde, was born about 1535, at East Ardsley, and married, in 1560, Jane, daughter of John Amyas. She died August 30, 1609, and he died May, 1587. He was an eminent astronomer, and introduced into England in 1557 the Copernican system,against the opposition of the scientist of his day, and in recognitionof this service to astronomy a sphere was later added to and surmounted the family coat-of-arms.

The proto-Copernican Astronomer of England, inasmuch as he was the first to make known in that country by his writings the discoveries of this remarkable man, who delayed for a long time the publication of hisfamous work. on accountof the opposition and persecution to be feared from persons who considered its teachings opposed to those of the Bible. Although completed in 1530, it was not printed till 1543, when its author was on his death-bed. Works based on the new system (which revolutionized the science of astronomy) by Rheticus and Reinhold had appeared in Germany a few years earlier, but the "Ephemeris" of John Field for 1557 which was published in that year, was the first opportunity afforded the people o England of becoming acquainted with the true motions of the heavenly bodies. In the following year he issued a similar work, calculated for1 558, 1559, 1560. Probably these were not his only publications, but no others have come down to us, and only two copies of these are known to exist, the British Museum and Bodleian Library, at Oxford, each possessing both works.
