Wales in 44 historical maps: 1150-2018 (134 pages). The name Wales (and Welsh) derives from the Germanic root Walh (plural Walha). The name refers to the Celtic tribes known to the Romans as Volcae, being used to identify all Celtic inhabitants of the Roman Empire. The Welsh name for Wales is Cymry. The word is descended from the Brythonic word combrogi, meaning “fellow-countrymen”. The Latinised form is Cambria. It has survived in various geographical names; e.g. the Cambrian Mountains, which cover much of Wales. (They also gave their name to the Cambrian geological period.) The name Cambria was also used on the earliest printed maps of Wales, at the end of the 16th century. On later maps it would become Wallia (Latin) and Wales (modern English).

Switzerland in 44 historical maps: 1525-2018 (134 pages). The name Switzerland (Schweiz, Suisse) means Land of the Switzers (Swiss people). It refers to Schwyz, one of the founding cantons of the country. Its origin is uncertain: it may be derived from the Anglo-Saxon term swiþ- (meaning “strong”) or from the Germanic word swint- or Celtic word sveit- (“clearing”). The present name came into use on maps during the 17th century. On earlier maps the Latin name Helvetia was used. This name refers to the Celtic tribes which lived in the area, prior to the people who immigrated from Germany. The first separately printed maps of Helvetia appeared in the early 16th century.

Surinam in 35 historical maps: 1522-2018 (116 pages) The name Surinam comes from Surinen people, the earliest known native American inhabitants of the region. From 1667 till 1975 the country was a colony of The Netherlands. It had been governed by the WIC (West Indies Company), the counterpart of the VOC (Dutch East Indies Company). On some antique maps the name Dutch Guyana is used to identify the colony/country and distinguish it from the neighbouring areas British Guyana (to the West) and French Guyana (to the East). Maps of the south-American region Guyana already appeared at the end of the 16th century. Separate (printed) maps of Surinam, mostly made by Dutch cartographers in service of the WIC, appeared in the early 18th century.

Saudi Arabia in 42 historical maps: 1154-2018 (130 pages). Saudi Arabia means “Arabia of the Sauds”, referring to the ruling dynasty. The dynasty itself took its name from the patriarch Saud, whose name means ‘constellation’. Arabia itself is a Latin name, probably of Semitic origin, although as early as Ancient Egypt the region was known as Ar Rabi. The first separate map of the region was designed by Ptolemy (150AD). The map was worked out again by European cartographers at the end of the 15th century. The first separately printed maps of (Saudi) Arabia appeared in the late 16th century.
