An Act of Parliament passed in 1563, entitled "An Act for the Translating of the Bible and the Divine Service into the Welsh Tongue", ordered that both the Old and New Testament be translated into Welsh, alongside the "Book of Common Prayer". This translation – completed by the then bishop of St David's, Richard Davies, and the scholar William Salesbury – was published in 1567 as "Y Llyfr Gweddi Gyffredin". A further revision, based on the 1662 English revision, was published in 1664.
