Pratt, or Prat, was born in either 1658 or 1659, probably in London. He died on 14 November 1723, also probably in London. He was educated at the Merchant Taylors’ School and then at Cambridge, although no record of his time there has survived and he does not appear to have taken a degree. Entering the clergy he became rector of Kenardington, Kent in 1682, vicar of All Hallows, Tottenham in 1693 and minister of the Savoy Chapel and canon of Windsor both in 1697. He served as chaplain to the Princess Anne, and as sub-preceptor to the Duke of Gloucestershire. In 1706 he was appointed dean of Rochester; he was also appointed vicar of Goudhurst, Kent and Twickenham, Surrey.
