Cosmography of Claudius Ptolemy

The cosmography was the science of description of the Earth and outer space in the Middle Ages. Cosmographic works were devoted to geography, geology, and astrology and were concerned with historical, spiritual, and moral aspects of the medieval worldview. The first globes and cartographical depictions of our Earth are attributable to medieval cosmographic works. An especially beautiful version of these teachings is the Cosmography of Claudius Ptolemy. The work originates from the second century after Christ and was lost for over 1,000 years, until it reemerged during the early Italian Renaissance. It contains 44 maps, of which 29 fill a double page. Furthermore, there are numerous colorful and golden miniatures and depictions in bordures that decorate the margins of the pages.

The Polymath Claudius Ptolemy

Ptolemy was a Greek mathematician, geographer, astronomer, astrologer, music theorist, and philosopher. His works on astronomy, geography, and astrology were regarded in Europe as important, comprehensive collections of data and standard scientific texts until the early modern period. His earlier world atlas revolutionized the geographic perceptions of the Renaissance. Claudius Ptolemy created maps of the world he knew and followed mathematical principals, which founded modern cartography. He introduced the system of longitude and latitude. His cosmography was given new life by some of the most gifted Renaissance artists.

The Cosmography in a New Garment

The important didactic piece originally spanned eight scrolls. These were incorporated into a single codex during the refashioning. The new edition was commissioned in 1471 by Duke Federico da Montefelatro. This manuscript is divided into eight books, exceedingly talented masters inscribed and illustrated the pages. Applications of various colors and gold make treasures of the special miniatures. Scientific insights were made understandable through charming pictures. As such, these early cartographical achievements succeed in impressing their beholder up to today.
