Question: Where is the treatise that influenced Godwin's astronomical theories published?
Sentence (from "The Man in the Moone"): Godwin's astronomical theories were greatly influenced by Galileo Galilei's "Sidereus Nuncius" (1610), but unlike Galileo, Godwin proposes that the dark spots on the Moon are seas, one of many parallels with Kepler's "Somnium sive opus posthumum de astronomia lunari" of 1634.
