These speculations were reinforced by Brasseur de Bourboug's own references to Plato's descriptions of the culture and society of Atlantis, which Brasseur believed was continued by ancient Maya civilization, in his book "Quatre Lettres sur le Méxique" (1868). In this publication, Brasseur de Bourbourg made extensive parallels between Maya and Egyptian pantheons and cosmologies, implying that they all had a common source on the lost continent of Atlantis. He developed these ideas further in his publication "Quatre lettres sur le Mexique" (1868), which presents a history of Atlantis based on his interpretation of Maya myths. His writings inspired Augustus Le Plongeon and also Ignatius L. Donnelly, whose book "" contains numerous references to Brasseur de Bourbourg's scholarship. However, an academic wrote in 1875 that not a single contemporary scholar accepted Brasseur de Bourbourg's theories about Atlantis.
