Protogaea
From Wikipedia, the free encyclopedia

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 Unpublished in his lifetime, but made known by Johann Georg von Eckhart in 1719,[2] it was conceived as a preface to his incomplete history of the House of Brunswick.[3]
Protogaea is a history of the Earth written in conjectural terms; it was composed by Leibniz in the period from 1691 to 1693.[4] A summary in Latin was published in 1693 in the Leipzig Acta Eruditorum.[5] The text was first published in full at Göttingen in 1749, shortly after Benoît de Maillet's more far-reaching ideas on the origin of the Earth, circulated in manuscript, had been printed.[6]
