A crowded wall of Chumash cave paintings made with white, black, and red pigments. A black circle is positioned between three X marks. Two are enclosed in circles, and one of the circles has had stick figure legs added. The black circle has been defaced with graffiti

In 1677, the area of California that the Chumash historically live in experienced a total eclipse. This eclipse also happened to have Mars and Antares (a red supergiant) align in a visually distinctive way near it, and these pictographs are believed to be their record of the event. The painted crosses are believed to depict stars, with a black circle representing the eclipse itself. The star at the bottom right is interpreted as Mars, having been depicted with legs: a ‘wandering’ star due to its irregular path across the night sky through the year.
