Barry Eric Odell Pain (28 September 1864 – 5 May 1928) was an English journalist, poet and writer.

De Omnibus has long been out of print but may be found at various on-line locations including at archive.org; a digitised (by Google) copy from New York Public Library. The book rather enigmatically names “The Conductor” as its author (the true author’s name appearing in parentheses) – evidently a pun on [omni]bus conductor.

Arthur Linfoot also read De Omnibus during his holiday in St. Andrews, recording it in his diary on the day after he started to read Omar Khayyám, 30 June 1915.
