^BFrench solar eclipses of 1724 and 1912.^b Historical artwork of people watching the total solar eclipse of 22 May 1724 (upper left) and the annular solar eclipse of 17 April 1912 (lower right). Both eclipses were visible from Paris, France. In both cases, the observers are using darkened glass with which to view the eclipse. A solar eclipse occurs when the Moon passes in front of the Sun, as seen from the Earth. When the Moon is slightly further from the Earth than normal, an annular eclipse takes place. Total solar eclipses usually occur less than once a year, and can only be seen from a small area of the Earth’s surface. Centuries can pass before another total solar eclipse is visible from the same location. Artwork published in 1912, in the Parisian daily newspaper ^ILe Petit Journal^i.
