Heaven and Earth (originally published 1958) by Gabrielle Henriet is a 75-page book promoting a Flat Earth theory based on the belief in a literal, solid dome or firmament spanning over the Earth. The text argues that the earth is stationary and not rotating, challenging modern astronomical models of a solar system. Henriet argues that her interpretation is based on a re-examination of data that was misinterpreted by modern science, favoring ancient, traditional viewpoints. The work is primarily categorized as early flat-earth literature.
