Autograph Letter Signed ‘Is. Williams’, about “the Proof Sheets of the Thoughts in Past Years”, with mention of The Mountain Home, one of the sections of the work. 1 page 7 x 4½ inches. Trinity College [Oxford], Tuesday, undated. Uncommon. Isaac Williams (1802–1865), poet and theologian, was a prominent member of the Oxford Movement, acquainted with John Keble and, like the other members of the movement, associated with Oxford University. He wrote religious poetry and one of the movement’s famous tracts: “Reserve in communicating Religious Knowledge”. From 1842 to 1848 Williams was curate to Thomas Keble (younger brother of John Keble) at Bisley, near Stroud. Keble set the pattern for Tractarian observance by his practice of daily services and gathered around him a group of clergy of sympathetic views who were later described as the ‘Bisley school’ of the Oxford Movement.
