Thomas Vaughan, the twin brother of Henry Vaughan, used the term in his Anthroposophia Theomagica in the 17th century.
"The brothers were born at Newton in Breconshire in 1621. In his years in London Vaughan devoted himself to alchemical experiment and theory. He published a series of treatises, the first three of which appeared in 1650. These were Anthroposophia Theomagica: or a Discourse of the Nature of Man and his State after Death; Grounded on his Creator's Proto-Chemistry and verified by a practical Examination of Principles in the Great World, Anima Magica Abscondita: or a Discourse of the universal Spirit of Nature and Magia Adamica: or the Antiquitie of Magic.
All three were published under the name of Eugenius Philalethes, as were Lumen de Lumine: or a New Magical Light, which appeared in 1651, and Euphrates: or the Waters of the East, published in 1655. In 1652 there had been published Aula Lucis: or The House of Light, attributed to one S.N., but identified by Henry Vaughan as one of his brother's works (S and N being the final letters of Thomas Vaughan's Christian name and surname)."
