Elementa eclipsium quas patitur tellus, luna eam inter et solem versante, ab A. 1815 usque ad A. 1860, ex tabulis astronomicis recentissime conditis et calculo parallactico deducta, typo ecliptico et tabulis projectionis geographicis collustrata
Elementa eclipsium is an 1815 astronomical treatise by Franz Ignaz Cassian Hallaschka, printed by Typis Theophili Haase, predicting solar eclipses visible on Earth from 1815 to 1860 for a scholarly audience of astronomers and mapmakers. The plates show hemispherical world maps overlaid with curved eclipse-path bands and small inset diagrams of the Moon's shadow crossing the globe, rendered in fine black line engraving on pale paper, useful for designers wanting schematic cartographic linework and orbital diagram motifs.
