Thomas Vaughan, the twin brother of the poet Henry, was a disciple of Cornelius Agrippa and a noted Rosicrucian and alchemist. He attended Jesus College Oxford (B.A. 1642) and was rector of St. Bridget's, Brecon. An associate of the reformer Samuel Hartlib, he engaged in a bitter controversy with Henry More of Cambridge. Vaughan published under the pseudonym "Eugenius Philalethes."
