Dr Arthur Kay or Kaye or Key (c.1631–1701) was educated at the University of St Andrews (M.A. 1664/65). He was vicar of Elmsted, Kent (1665–1673) and rector of St Andrew's, Canterbury (1673). He was admitted as Six Preacher at Canterbury Cathedral in 1670. It is recorded that he was given permission to be absent in France for four months in 1671.
Kay also worked as Library Keeper at the Cathedral. In the Treasurer's Book for 1679 he is recorded as receiving a half-yearly payment of £2–10–0 as Library Keeper; his colleague John Sargenson, the Precentor, received £2–0–0. In 1680 he also received 4 shillings for sweeping the Library at Midsummer, though this may simply be that he received the money to pay 'the woman' who previously received 4 shillings.
