Map of the world marked to show eclipse tracks during the Saros period, 1927-2164

Map of the world (Mercator Projection) by Edward Stanford, London marked to show eclipse tracks illustrating the Saros period between 1927 to 2164.

Map of the world by Edward Stanford Limited marked with the paths of totality for the Saros cycle of eclipses from 1927-2164. The time and location of solar and lunar eclipses repeats themselves over a period about 18 years. This series was discovered by Chaldeans over 2,500 years ago, and named by them the Saros. This map was modified by the drawing office of the Science Museum for an exhibition held in 1927. The display at the Science Museum in South Kensington was to celebrate the total solar eclipse that was going to pass over North Wales and North West England that year.
