Interesting regional map of Italy. Lower neatline trimmed, else a nice example. From an early edition of Magini's Geographia, based upon the work of Ptolemy.
Giovanni Antonio Magini was an accomplished Italian cartographer, astronomer, astrologer, and mathematician—in short, a Renaissance man. Born in Padua, he studied philosophy in Bologna. His first publication was Ephemerides coelestium motuum, an astronomical treatise published in 1582. In 1588 he was selected, over Galileo Galilei, to fill the chair of mathematics at the University of Bologna. He died in that city in 1617.
Magini operated under a geocentric understanding of the universe and created his own planetary theory consisting of eleven rotating spheres. He published this theory in Novæ cœlestium orbium theoricæ congruentes cum observationibus N. Copernici (Venice, 1589). In the 1590s he published works on surveying and trigonometry, as well as invented a calculator. In 1596, he published a commentary of Ptolemy’s Geographia, which was published in several editions and languages. He labored for years on an atlas of Italy, which was printed posthumously in 1620. To pay for this project, Magini served as the math tutor to the son of the Duke of Mantua, as well as being the court astrologer to the Duke.
