Johann Gabriel Doppelmayr’s (c. 1677–1750) ﬁrst pair of globes appeared in 1728; they were followed by a second pair of 20 cm (almost 8 inches) in 1730 and a pair of 10 centimetres (4 inches) in 1736. His globes were engraved by Johann Georg Puschner (1680–1749), who was also known as an instrument-maker.
The terrestrial globe displays many of the recent discoveries of the early 18th century, but it also pays homage to several important explorers of the past. Many tracks are shown, including those of Magellan, Le Maire, Tasman and Dampier, as well as the very recent journey of the Dutchman Jacob Roggeveen (1659–1729), who discovered Easter Island in 1722 during an unsuccessful expedition to ﬁnd the mythical great southern continent.
An address to the reader is surrounded by 12 charming portraits of famous explorers with Martin Behaim, a fellow citizen of Nuremberg and globe-maker, in the most prominent position.
Doppelmayr, who was professor of mathematics in Nuremberg, had a wide-ranging interest in the Enlightenment concerns of natural philosophy (an 18th-century term for science), including electricity. He travelled extensively, spoke several languages, and was a member of several scientiﬁc societies, including the Royal Society in 1733.
