Geographic depiction of the globe comes in several forms but this one is still a little unusual.  The Modern  Geography… a treatise on the newly-invented Plane Globe  contains essentially two cardboard hemispheres mounted as volvelles with accompanying text description and detailed instructions for use.  The maps are beautifully engraved and hand coloured, centred on the North and South Poles fixed with brass measuring rules.  Curiously for the time the measure is marked in centimetres rather than inches.

This plane globe was issued at a time when geography was emerging as an academic discipline, indeed the Royal Geographical Society had been founded less than a decade previously.  The volume was printed in Manchester in around 1839 by Bancks and Co. which was responsible for the impressive large scale Plan of Manchester and Salford (1832).

The globe form was considered the ultimate in geographical aids so that students could fully understand spatial relationships and had a part to play in instructing astronomers and navigators, however they are bulky and unwieldy. To overcome the problem of portability, convenience and legibility ‘Inventor’ Joseph Bentley has devised what he describes as a ‘Plane Globe’ as a device for learning, as he says on the title page “… for the student, the man of business, and all classes who wish to know something of the world we live in; …”.  The Modern Geography was reviewed in The Spectator (vol.12, June 29, 1839) who were rather impressed

“…is clear and comprehensive; containing an immense amount of statistical and other useful information, packed into a close compass, and so well arranged that individual facts appertaining to any country are easily ascertained: for instance, the latitude and longitude, population, products, and manufactures of every chief town in the world. The topography of the British Isles is still more fully and minutely described: the boundaries and extent of each country – the population, constituencies, and parishes – the average rent of and per acre, the ratio of crime and instruction, and the average amount of productions – are stated. The general account of the different states and kingdoms, though concise, is lively and pregnant with matter. In a word, the publication is a complete multum in parvo of ‘Geography and the use of the Globe.”

The hemispheres are attached to the boards with beautifully illustrated figures in the corners including an orrery and a telescopic view of the moon. The Plane Globe is bound in square quarto, quarter red morocco with green cloth covered boards and black paper title label to upper board.  When the volume arrived in the library as part of the copyright intake it was one of the last books placed in the ‘Med.’[Medicina] classification which is one part of the Bodleian four-part classification. In the later years the distinction by faculty began to be disregarded, and books were added where there was space on the shelves, accounting for this rather anomalous shelfmark.

Not a lot is known about Joseph Bentley himself but there is mention of the availability a celestial plane globe but none seems to have survived. The Modern Geography was later issued without the globe element so the lack of further editions of this work and the high price it probably means it was not a commercial success.
