'Traveller's Companion' (Road Maps)

John Cary’s Traveller’s Companion, published from 1789 to c.1835

The maps from the Traveller’s Companion, prepared at the request of the Postmaster General, were based on an entirely new survey of the Turnpike roads of England & Wales carried out by Cary from 1780 onwards. On publication, the maps proved to be immensely popular and had a considerable influence on the formative work of the Ordnance Survey Office, which was established in 1791.
