Protogaea

Protogaea[1] is a work by Gottfried Leibniz on geology and natural history. Unpublished in his lifetime, but made known by Johann Georg von Eckhart in 1719,[2] it was conceived as a preface to his incomplete history of the House of Brunswick.[3]

Life

Protogaea is a history of the Earth written in conjectural terms; it was composed by Leibniz in the period 1691 to 1693.[4] The text was first published in full in 1749, shortly after Benoît de Maillet's more far-reaching ideas on the origin of the Earth, circulated in manuscript, had been printed.[5]

Views

Protogaea built on, and criticized, the natural philosophy of René Descartes, as expressed in his Principia Philosophiae.[6] Leibniz in the work adopted the Cartesian theory of the Earth as a sun crusted over with sunspots.[3] He relied on the authority of Agostino Scilla writing about fossils to discredit speculations of Athanasius Kircher and Johann Joachim Becher;[7] he had met Scilla in Rome a few years earlier.[8] He took up suggestions of Nicolaus Steno that argued for the forms of fossils being prior to their inclusion in rocks, for stratification, and for the gradual solidification of the Earth.[9]
