Eirenaeus Philalethes

Eirenaeus Philalethes (the peaceful lover of truth) was a 17th-century alchemist and the author of many influential works. These works were read by such luminaries as Isaac Newton, John Locke, Gottfried Wilhelm Leibniz, Robert Boyle, and Georg Stahl. Newton's extensive writings on alchemy are heavily indebted to Philalethes, although Newton incorporated significant modifications as well.

The real identity behind the nom de plume of Eireneaus Philalethes was long shrouded in mystery. Recent research, however, has shown that the author was George Starkey (1628-1665), an expatriate American living in London.

First printings of Philalethes' tracts were published between 1654 and 1683:

A number of these tracts, including the Three tracts and the Introitus were also included in the Musaeum Hermeticum of 1678.

All English works of Philalethes have been recently compiled in one volume.
