A series of late Victorian astronomical diagrams on one plate, from Bartholomew's Pocket Atlas of the World. The illustrations, chromolithographically printed, represent the phases of the moon, the actions of the moon on the spring and neap tides, the seasons of the northern hemisphere and their dates, a comparative size chart of the sun and planets (excluding Pluto, which was not discovered until 1930), a description of solar and lunar eclipses, and an illustration of the orbits of the planets and their distances from the Sun in millions of miles. On the left hand side of the verso, a supplementary diagram shows the periods of revolution of the planets closest to the Sun: Mercury, Venus, Earth (with the Moon's orbit shown), and Mars.
John Bartholomew & Son was founded by John Bartholomew Senior (1805 - 1861) in 1826. Initially the firm printed maps for external companies, though under John Bartholomew Junior and his son John George Bartholomew, the company achieved much greater success after making the decision to commission and print their own map series. In particular, the firm was responsible for the Times Survey Atlas of the World (1922) and successive Times Atlases.
