Description

An attractive example of Gerard Mercator's Ptolemaic map of Libya and Egypt, including a number of mythical and not-so-mythical creatures.

The map stretches from the Gulf of Sidra in the west to the Red Sea in the east. The Nile River charted in some detail, with dozens of cities and settlements noted.

While Mercator is perhaps most famous for his maps of the Modern World, one of his life ambitions was to write an improved and corrected edition of Ptolemy's Geographia.

Gerard Mercator Biography

Gerard Mercator is one of the most famous cartographers of all time. Mercator was born in Flanders and educated at the Catholic University in Leuven. After his graduation in 1532, Mercator worked with Gemma Frisius, a prominent mathematician, and Gaspar a Myrica, a goldsmith and engraver. Together, these men produced globes and scientific instruments, allowing Mercator to hone his skills.

With his wife, Barbara, Mercator had six children: Arnold, Emerentia, Dorothes, Bartholomeus, Rumold, and Catharina.  In 1552, Mercator moved to Duisburg from Leuven, where he lived for the rest of his life. In 1564, he was appointed the official cosmographer to the court of Duke Wilhelm of Cleve.

Mercator’s most important contribution was the creation and popularization of a projection which now bears his name. On Mercator projection maps, all parallels and meridians are drawn at right angles to each other, with the distance between the parallels extending towards the poles. This allowed for accurate latitude and longitude calculation and also allowed navigational routes to be drawn using straight lines, a huge advantage for sailors as this allowed them to plot courses without constant recourse to adjusting compass readings.

Mercator’s other enduring contribution to cartography is the term “atlas”, which was first used to describe his collection of maps gathered in one volume. The Mercator atlas was published in 1595, a year after Mercator’s death, thanks to the work of his sons, particularly Rumold, and his grandsons.
