by J. O. (James Oliver) Bevan
James Oliver Bevan (1843–1930) was a British author and clergyman whose surviving record shows a wide range of interests, from archaeology and ancient history to theology and philosophy. Catalog and library listings connect him with books including The Towns of Roman Britain, Egypt and the Egyptians, The Birth and Growth of Toleration, Handbook of the History & Development of Philosophy, and University Life in the Olden Time.
One of the clearest glimpses of his public profile comes from The Towns of Roman Britain (1917), where he is styled as the Rev. J. O. Bevan, M.A., F.G.S., Assoc. Inst. C.E., F.S.A., and as a former scholar of Emmanuel College, Cambridge. In that book he presents Roman Britain as a subject for curious general readers as well as serious students, which fits the practical, explanatory tone found across the works attributed to him.
A family-history record identifies him as born in 1843 and deceased in 1930. Reliable biographical detail beyond that is limited in the sources I could confirm, so it seems safest to remember him as a learned early-20th-century writer whose books aimed to make big historical and religious subjects approachable.
