First is a delightful small double hemisphere celestial map based on the observations of Philippe de la Hire, a famous French astronomer. La Hire was one of the first to present the full celestial skies in a double hemisphere format. The twin hemispheres include the allegorical representations of the constellations. Above and below are small diagrams of the Sun, Saturn, Jupiter, Venus, Mars, Mercury and the Moon from the observations of Cassini, Kircher, and Galileo. The second has several diagrams showing the correlation between the earth and the sky.
