Spanish philosopher. He taught at Toulouse. His Liber Naturae sive Creaturarum or Theologia Naturalis (first published in 1484) achieved fame through M. de Montaigne, who translated and defended it in 1569. Its prologue, maintaining that it is possible for human reason to discover the contents of the Christian Revelation in nature alone, was put on the Index in 1559. The book itself, however, was highly esteemed.
