Eugenius Philalethes

Pseudonym of alchemist Thomas Vaughan, brother of Henry Vaughan, the "Silurist" poet. Eugenius Philalethes has often been confused with Eirenaeus Philalethes (or Philaletha), another alchemist. The scholar Arthur E. Waite made this error in his book The Real History of the Rosicrucians (1887). He corrected it the following year, both in his new edition of the Lives of Alchemystical Philosophers (1888) and his edition of The Magical Writings of Thomas Vaughan (1888).
