Isaac de La Peyrère

Born in Bordeaux and usually dated either 1594 or 1596, Isaac de La Peyrère was a French writer, theologian, and lawyer from a Protestant family often described as having Portuguese New Christian or Marrano background. He moved in learned circles and served the Prince of Condé, which placed him close to political life as well as the intellectual debates of his age.

He is best known for Praeadamitae (Pre-Adamites), a work that argued there were humans before Adam. That idea challenged traditional Christian readings of Genesis and helped make him a striking early voice in biblical criticism. He also wrote on the future restoration of the Jews, showing a wider interest in sacred history, prophecy, and the destiny of different peoples.

His books caused intense controversy, and after his arrest in the Spanish Netherlands he publicly recanted and converted to Catholicism. Even so, his writings continued to echo through later debates about scripture, history, and human origins, giving him a lasting place in the story of early modern religious thought.
