Johann Georg Gichtel, a disciple of Jakob Böhme, and his book Theosophia Practica (1696), in which Gitchtel directly refers to inner force centers, a concept reminiscent of the chakras.[13]

Johann Georg Gichtel (March 14, 1638 – January 21, 1710) was a German mystic and religious leader who was a critic of Lutheranism. His followers ultimately separated from this faith.

He became an ardent disciple of Jakob Böhme, whose works he published in 1682 (Amsterdam, 2 vols); but before the time of his death, he had attracted to himself a small band of followers known as "Gichtelians" or "Brethren of the Angels," who propagated certain views at which he had arrived independently of Böhme.

Charles L\He is the author of the Relación de las cosas de Yucatán in which he catalogues the Maya religion, Maya language, culture and writing system. This manuscript was written around 1566 on his return to Spain; however, the original copies have long since been lost. The account is known to us only as an abridgement, which in turn had undergone several iterations by various copyists. The extant version was produced around 1660, and was discovered by the nineteenth century French cleric Charles Etienne Brasseur de Bourbourg in 1862. Brasseur de Bourbourg published the manuscript two years later in a bilingual French-Spanish edition, entitled Relation des choses de Yucatán de Diego de Landa.
