The fourth edition of the collected poems of William Mason (1725- 1797), including his first widely praised composition, 'Musaeus: a Monody to the Memory of Mr Pope' (1774). Mason later achieved recognition for a biography of his friend, poet Thomas Gray, which inspired James Boswell to undertake a similar approach in his Life of Samuel Johnson (1791).

This copy belonged to John Trevenen Penrose (1853-1926), vicar of St Mary's, Barnard Castle.
