Ricardus Anglicus (Q952078)

has been identified with Richard of Wendover (by John Ferguson), with Robert of York (died c. 1348) (by Lynn Thorndike), and with Richard of Middleton (by Hermann Kopp). More recently, Joachim Telle disproved these attributions. José Rodriguez Guerrero attributes the Correctorium alchemiae to Bernard of Trier (not to be confused with the fictional Italian alchemist Bernard Trevisan), whom he identifies with Eberhard von der Marck-Aremberg (1305–1387), a law graduate and clergyman, who became chorbishop of Cologne before leaving the church to marry. He further argues that Bernard of Trier is also the author of the later version of the text entitled Corrector (fatuorum).
