About this sheet

Antique map titled 'Motus Comtarum in Hemispaerio Australi (..)'. This uncommon chart depicts the passage of comets in the southern sky between the years 1530-1704. Centered on the ecliptic poles and shows the constellation figures based on classical mythology, without showing the stars. The paths of dozens of comets are illustrated, eincluding those sighted by Tycho Brahe, John Flamsteed, Johannes Hevelius, and many others. The chart also identifies "newly discovered" stars between 1572-1686. Surrounding the hemisphere are various diagrams related to comets and a chart listing details regarding the comets and stars depicted on the charts. Published by the Homann Heirs, circa 1740.
