German poet and theologian, founder of Rosicrucianism, 1586-1654, supposed author of Allgemeine und General-Reformation der ganzen weiten Welt and Fama Fraternitatis, wrote under pseudonyms of Christian Rosencrutz, Menippus and Florentinus de Valentia.
Fishburn and Hughes: "CF 29: A German poet, satirist and theologian who was converted to the Lutheran Church and composed a number of interpretative and didactic works on religion, in Latin and German. Andreä wrote also under the pseudonyms Christian Rosencrutz, Menippus and Florentinus de Valentia. De Quincey (Collected Writings, vol. 13, 405-10) alleged that Andreä was the anonymous author of the basic books of Rosicrucianism. According to him Andreä conceived this secret society in an attempt to reform the German people, whom he considered corrupt and evil. He envisaged a body of noble and learned men acting under the direction of a 'most enlightened one', bent on redressing public morality. To attract proselytes, he emphasised that the society was the repository of oriental mysteries and that it had already lasted for two centuries - one reason why he did not claim authorship of the texts. There are strong parallels between the story of Rosicrucianism and the imaginary society of 'Tlönistas': both can be seen as creating 'hrönir', ideal objects which are gradually embodied and become accepted and absorbed into our material world."
