On 3 July 1769, Gibson issued proposals for printing by a guinea subscription a commentary upon part of the fifth journey of Antoninus through Britain, but his death in 1772 interrupted the design. In 1795, the manuscript was offered to John Nichols by the possessor, Daniel Bayley, fellow of St. John's College, Cambridge. Nichols published it with considerable additions in ‘Miscellaneous Antiquities in continuation of the Bibliotheca Topographica Britannica’ as ‘A Comment upon part of the Fifth Journey of Antoninus through Britain, in which the situation of Durocobrivæ [Durobrivæ?], the seventh station there mentioned, is discussed; and Castor in Northamptonshire is shown, from the various Remains of Roman Antiquity, to have an undoubted Claim to that Situation. To which is added a Dissertation on an Image of Jupiter found there. By the Rev. Kennet Gibson. … Printed from the original MS. and enlarged with the Parochial History of Castor … to the present time. To which is subjoined an Account of Marham,’ &c. (by Richard Gough), 4to, London, 1800; 2nd edition, enlarged, 4to, London, 1819.[1]
