Artephius

Artephius (or Artefius) (c. 1150) is a writer to whom a number of alchemical texts are ascribed. Although the roots of the texts are unclear and the identity of their author obscure, at least some of them are Arabic in origin. He is named as the author of several books, the ''Ars sintrillia'', ''Clavis sapientiae'' or ''Clavis maioris sapientiae'', and ''Liber secretus''. Provided by Wikipedia
