The influence of Theodor von Oppolzer’s Canon der Finsternisse (Canon of Solar Eclipses) continued well into the 20th century. Although Oppolzer’s maps were drawn as circular arcs from three calculated points, his tables continued eclipse elements that allowed his successors to create more accurate and detailed maps. In 1923, J. Fr. Schroeter published his Spezieller Kanon der Zentralen Sonnen- und Mondfinsternisse, welche innerhalb des Zeitraums von 600 bis 1800 n.Chr. in Europa sichtbar waren.

Schroeter’s eclipse canon is the most accurate mapping of historical European eclipses up to this date. Solar eclipses from the year 600 to 1800 are included in this volume. These maps were made for the purpose of analyzing past records of solar eclipses for the determination of the chronology of early Europe.

Below is a sampling of the maps from this volume.
