Manuel Antonio de Rivas
Manuel Antonio de Rivas was a Franciscan friar in Mérida, a Spanish colonial town on the Yucatán Peninsula. Details of his life are sketchy, though there are court documents that prove that in the 1770s he was accused of heresy. He is best known for an account of a journey of lunar discovery, Syzygies and Lunar Quadratures, which is credited as the first science fiction text written in the Americas.
